If it is simply to produce ammonia, without considering the cost, in fact, the synthesis of ammonia has been successful, because in the process of reaction, a steady stream of ammonia has appeared.

The probability of industrial production is a big problem, and in the current state, knowing that iron can be used as a catalyst for ammonia synthesis, there is only one thing left to find a reasonable temperature and pressure.

This is not a small problem for the Dinghai Navy, the problem of heating is not big, as long as it is heated, it is fine, but it is a little difficult to control the temperature above 300 degrees.

The maximum temperature of the mercury thermometer is about 300 degrees, and above it, it is a metal thermometer, and this thermometer is not something that the Navy can make.

If it is a traditional steelmaking, you can also judge the temperature by observing the color of the flame, and some experienced masters can judge the approximate temperature by feeling, but synthetic ammonia is a completely closed system, and it is impossible to see it under the premise of pressurization.

In later generations, sensors and endoscopes could be made, but in this era, it was simply impossible, so it could only be done by feeling.

If heating is still an acceptable thing, then pressure is a difficult point, and under the premise that there is no power system, pressurization is a very difficult, coupled with control, under the premise that it cannot be accurately calculated, many of them rely on calculations.

Obviously, with the current technical strength of the navy, it should be somewhat difficult to meet the pressure required for synthetic ammonia, and it can only be used as much as possible.

So far, the maximum pressure is about 3 atmospheres, this pressure and the future dozens of pressure, or even hundreds of atmospheres can not be compared, but it is already the limit that the navy can reach, under high temperatures, the synthesis of ammonia will be carried out slowly, it will take more than a day and a night to complete less than 10% of the synthesis.

This synthesis speed is really very slow, and the cost of making fertilizer will be much higher than the cost of food that increases the yield brought by fertilizer, but when it is used as explosives, it is no problem.

At present, because the whole of China does not produce saltpeter, Zhao Xin only blends black powder, and even this black powder is not perfect black powder, and the difference between power and perfection is not small.

The emergence of ammonia, coupled with some chemical reactions, turns ammonia into nitride, and then makes all kinds of gunpowder, Zhao Xin does not know the formula of TNT, but it can be studied from the middle, at least, one is the simplest, nitroglycerin, and nitrocellulose, one is the reaction of nitric acid and glycerin, and the other is the reaction of cotton and nitric acid, which is not a problem.

Ethylene and synthetic ammonia, these two are entry-level synthetic reactions, the former is the simplest organic matter, and the latter, once in history, was considered to be an organic matter, but when it was later divided and defined, when the carbon-containing elements were defined as organic matter, this was classified as an inorganic matter.

However, it should be the most organic-like inorganic matter, through ammonia, urea can be easily produced, this is a standard organic matter, or the more complex kind of organic matter.

The emergence of the two products is considered to have opened the door to organic matter, but these are the most basic gets, and the applicability is not so strong.

Zhao Xin is not in a hurry, from the emergence of organic matter, to the development step by step, and finally to the extent of a wide variety of later generations, that is countless time, countless scientists, with many years of hard work to achieve, Dingjun, how long has it been now.

The two products have squeezed out Zhao Xin's understanding of organic matter, similar to the dehydration of ethanol, which is more in the organic reaction, but Zhao Xin can't personally devote himself to it, he just needs to point out.

Some of the main reaction methods in later generations, heating, cracking, condensation, dehydration, chemical combination, and even the final electrolysis, these reaction methods can be passed by, and some of the products that have been studied are decomposed, which requires a long time of trial and accumulation of experience, and then the process of development.

The research of compounds, especially the research of organic compounds, will continue at a certain time, but this research is no longer carried out by Zhao Xin, but by the following personnel.

The chemical industry is a very magical field, he can give birth to completely different performance, or even the opposite thing, of course, this industry, because of the use of acid and alkali and other corrosive solutions, or high temperature and high pressure process, in the production, there will also be toxic and harmful gases, or residues generated, even in the later generations, is also a strictly controlled industry.

Especially in the 21st century, under the premise that environmental issues are becoming more and more important, it is common to hear that some chemical companies that fail to pass the environmental assessment are either relocated or closed.

Even the science and technology of the 21st century have no way to avoid the pollution caused by the chemical industry, and under the current technical level of the Dinghai Navy, once the chemical plant is put into operation, it will inevitably carry huge pollution.

There is no way to do this, not to mention that polyethylene has not been made, and even if it is made, there is no way to solve the problem of pollution alone.

Pollution, this is the eternal problem of chemical enterprises, especially in the initial stage of production, there is no way to solve the pollution, or the cost will rise to the point of unbearable, for example, the cost of a dime, but because of the problem of solving pollution, it is increased to 1, or even 2, or it is unavoidable.

For example, in chemical enterprises, a small part of the toxic and harmful gases produced in the production process can be degraded by physical and chemical methods, but most of them are not.

The chemical industry of the Dinghai Navy is promoted by Zhao Xin, and under the forced promotion of the card system, it has reached the current level, and there are many missing parts, such a defective chemical industry, let alone in the Dinghai, such a densely populated place, even in a sparsely populated place, can not be easily opened.

The laboratory still continues, there is no need to study industrial production for the time being, and it is a little early to start the era of organic matter, continue to research, find ways to reduce pollutants, and by the way, reduce the cost.

The laboratory, in order to produce something, can be said to be cost-free, from expensive things to cheap things, which can only be done in the laboratory.

Things, first of all, must be produced first, only after production, can be studied, the characteristics of this thing, can be studied, what aspects of this thing, what aspects of the role, only extremely high value products, can have the basis for industrial production.

The experiment of any basic material is costly, it has formed a huge problem, a large amount of investment, but there is no transformation process, it is still the beginning, the whole laboratory is not much in parallel to open the project, but in the research process of ethylene and ammonia, various chemical reactions, various catalysts and additions, the cost has increased significantly.

Even if Zhao Xin has a large amount of funds to fill it and support the entire development, but for Dingjun, this is not a healthy development, and he must find a way to reduce it.

The laboratory has a fixed development model, and under the standards of the laboratory of later generations, the Dinghai Navy is actually constantly supplementing, especially for the in-depth study of the products of the two kinds, and a series of discoveries will appear almost in the foreseeable tomorrow.

For Zhao Xin, in terms of efficiency, the research in the laboratory is no longer more efficient, not to mention that now, the first detailed battle report on the Ryukyus has returned.

As expected, 2,000 troops were dispatched, and there was such a sail warship, which surpassed the battleships of this era, and after the crossbow weapon was equipped with explosives, it was upgraded to a quasi-cannon, under the trinity, not to mention that there was not much armament, and it was relatively backward in all aspects, even if it was a heavy cavalry of 20,000 Liao, it was also gray.

The generational difference in weapons is enormous, and when the army does not have weapons that threaten the battleships, this in itself is an imbalance, except when it is out of the shore, where crossbow arrows and longbows cannot be fired.

It's a pity that the natives didn't have these, and the final result, of course, was a big victory for the Dinghai.

Sun Ji and the others did not send back the battle report as soon as they defeated the natives, they sent back the war report a few days later, after cleaning up the natives of the Taipei Plain and bringing the Taipei Basin into their jurisdiction.

Everything was going smoothly, the settlements were constantly expanding, the seizures from the natives, and the goods transferred from Quanzhou, there was no problem of food for the time being, and with this letter came a huge fleet of ships sent over, who, after sending soldiers and supplies to the Ryukyus, quickly turned around and waited for another trip to the Ryukyus.

This time, of course, it can't be all the supplies, the capacity of the huge fleet, in this era, even a few hundred years back, is very huge, if all the food is transported, mainly compressed biscuits and canned food from the military, it may be that these people who are currently scheduled to be sent to the Ryukyus by the navy may not be able to eat it all in a year.

This is completely unnecessary, as long as there is a transport fleet, in the future, among a large number of docks, there will be many sail warships put into production, when the time comes, even if the monsoon season comes, the Navy will have enough capacity to ensure the transportation of this route, the capacity will be higher and higher, and there will be no problems.

Well, there are many combinations in this selection of things to be transported.

This is the first large-scale landing, or thousands of miles away, the navy is very careful, in fact, before the first wave of reinforcements set off, preparations have already begun.

At that time, three choices were made, if the war situation is not smooth, there may be problems, then military support is certain, it must be a copy of the previous army transportation, at most in the middle of the trade-off,

The second direction is mainly materiel, and if there is not enough food seized from the natives, and an additional 2,000 people, or even more prisoners, food must be transported to ensure that the settlement does not collapse.

Now, according to the battle report sent back by the Ryukyus, the battle situation is going well, the combat effectiveness of the natives is almost negligible, 2,000 people are enough to solve the problem of the natives, and the food has also been solved, and when occupying the natives' cottages, a large amount of food has been obtained, at least, there is no shortage in a short time.

Since the first and second do not need to be executed, it is clear that the third must be executed.

The third is simple to say, that is, to use one, or multiple transports, to lay the foundation for a large-scale landing of the Dinghai Navy.

Before the establishment of the navy, there was no experience of large-scale landing, but in the development of the navy itself, it was experience.

What does it take for a city, a city with a sufficient population, and an industrial base?

First of all, it is a variety of basic materials, the basic materials that the Dinghai Navy transports to the Ryukyus are mainly steel, cement, and bricks, and the former, the construction of a large-scale steelmaking plant takes time, and it takes enough manpower.

In this way, in the early stage of the development of the Ryukyus, the steel plant could be postponed first, and the cement plant and brick factory had to be mentioned earlier.

The materials used in cement, mainly lime, bricks are mainly made of clay, both of which exist in large quantities in the whole of China and even in the world, and there is no problem of whether there are mines or not, so it is necessary to send enough engineers and skilled workers, as long as they are sent to the Ryukyus, and various factories are initially established, the demand for building materials in the Ryukyus can be reduced by at least more than half.

Cement factories and brick factories must be guaranteed at the first time, and their existence represents the expansion of settlements, but it is not all that needs to be transported to the Ryukyus urgently.

The next choice, there are two main ones, one is a large number of industries including shipyards, Ryukyu is a huge land, some are not suitable for the Dinghai Navy, or in the Dinghai, there is no way to expand the factory, can be sent to the Ryukyus, the location of the Ryukyus, from the Yangtze River estuary, from Quanzhou is closer, this is an advantage in itself, as long as there is enough capacity, when the Ryukyu factory is put into operation, it will inevitably create high profits.

There were many that could be sent to the Ryukyus, but under the constant consideration of the staff, one after another was vetoed, and the peasants were finally chosen.

That's right, in the second batch of people, in addition to the skilled workers of the cement and brick factories, the largest number of people were farmers, including 12 agricultural experts, 100 old farmers, and 500 young people.

You must know that the second batch of transportation personnel, a total of more than 800 people, and the number of purely agricultural personnel, more than 600 people, which accounts for more than 70% of all personnel, such a tendency is quite obvious.
