At present, the threshold of early chemical technology is low, and it does not even require much knowledge, as long as the formula can be imitated.

The dynamic significance of the existence of basic chemistry came from military purposes and living economy in the early days, and the development of chemistry was largely driven by the military industry, and then came to the civilian field, such as a series of important chemical inventions in the early days, all of which came from explosives.

The physics course is mainly based on natural science and basic mechanical motion physics, and no matter how high it is, it is useless, and Bailiyan can't remember those high top physics.

In 644, it was convenient for teaching and research, and at the beginning of the year, the excitation principle model and motor prototype of direct current and AC motor were made, which provided technical and theoretical reserves for promoting the motor revolution in the future.

Due to the danger of some chemical tests, the first half of the course is mainly taught, and the standardization of operation is emphasized.

After that, the basic test utensils such as test tubes and beakers were put in place one after another, and only some simple experiments were done at the beginning to prepare three acids and two bases, and then other chemical reagents were prepared with three acids and two bases.

Since then, the content of the lecture has deepened, and the difficulty of testing has increased one after another, and dozens of elements such as pure nickel, chromium, cadmium, tungsten, manganese, iron, copper, zinc, lead, strontium, platinum, calcium, sodium, hydrogen, oxygen, and chlorine have been prepared one after another, which has made the Gongpai and Yuke realize another world under the microcosm for the first time.

As for pharmaceuticals, they are roughly divided into three categories, one is the extraction of existing plants and herbs, such as the extraction of Lexian fruit, which isolates two narcotic substances.

The second is the extraction of fungi and mold secretions, such as the white mold found in the early years, using the rich culture method and temperature difference sterilization method, using beef broth as the culture medium, through generation by generation to breed to purify the target strain, and finally through the strain secretion to prepare the active ingredients.

This process takes several years or even more than ten years to repeat the process to purify, so as early as 636 Shengyuan, under the guidance of Bailiyan, Yicaotang initially differentiated strains for research, and successively began to cultivate and purify strains.

After gradually purifying the strain population, use a syringe to inject into a wax container and seal it to avoid exposure to air infection with miscellaneous bacteria, and place it in a refrigerator at 0 to 5 degrees Celsius to ensure the activity of the strain for half a year to one year.

After that, the strains are extracted every six months to replace the sterilization nutrient solution to form a system, and maintain its activity, and the strains can be stored for a long time, and continue to multiply and expand until the order of industrial production is met.

The third is the chemical preparation of medicines.

In addition, due to the promotion of the development of black soil in Wuping, a large number of willow and poplar trees have been cut down, providing additional resources for the production of aspirin.

Willow and poplar bark can be used as medicine, and it is salicylic acid that works. Willow, poplar bark and kiwi trees contain a large amount of salicylic acid, which is extracted from a reddish-brown liquid after soaking and boiling in clean water, and then acetyl passivation treatment can obtain acetylsalicylic acid, which is aspirin.

Although modern aspirin has been chemically produced, the production of willow and poplar is still a relatively convenient and low-cost means.

Aspirin is good for colds, fever, toothache, joint pain, rheumatic pain to inhibit platelet aggregation, prevent ischemic heart disease, angina, cerebral thrombosis, and even can be used as an adjuvant treatment of diabetes. All in all, there is no harm in taking two pills for the elderly who are not sick.

After the production of aspirin, Bailiyan was re-branded as "Everything" and sold it to the outside world, and for a long time in the future, this Everything's medicine has been an important source of income. In addition, sulfonamides are also extracted from coal, and the emergence of sulfonamides solves a great problem of early anti-inflammatory.

At the same time, after more than ten years of development, Yongxing City has completed the original accumulation of basic industrial industries, and the relevant technical conditions have matured, while the space in the city is becoming increasingly narrow.

The food, textile, pharmaceutical, medical and health supplies, oil extraction, winemaking, sauce making, ceramics, primary woodworking, leather and other pollution-free textile food industries will be relocated to Ruitian, and Yongxing City will retain core technology industries such as metallurgical coking, mechanical processing, weapons production, optical glass, core education, design and manufacturing research and development, medical research, and measuring tool manufacturing.

At the same time, the development of the black soil forest east of Wuping will be increased to meet the demand for basic raw materials needed by Ruitian.

The site of the upcoming chemical workshop is set in Lincheng, the main city of Lincheng is 150 miles east of Guangxin, and there is a small port backed by the sea.

In view of the pollution of the chemical industry, and Lincheng is more suitable for industrial sewage discharge, and at the same time, Lincheng is the earliest place where Baili Yanhuang Village originated, potassium nitrate and kaolin are found in Lincheng, which is conducive to the local supply of saltpeter, miscanthus to make nitric acid and two alkalis, and other industrial products.

Lincheng is now controlled by Guangxin, and the population has increased from 30,000 or 40,000 to 120,000 today, but the economy has not improved, and it has become a financial black hole in Beihai County.

Of course, it is obviously impossible for Guangxin to hand over Lincheng easily.

Yongxing City was built in 636, and two Wanshi-class ships were completed at the beginning and end of 641, during which after technological adjustments, two more mature and more scientific sail warships were built halfway, and two sail warships were built in 643, and ten Wanshi merchant ships were built at the same time, and the construction period was greatly shortened.

In 644, the Wanshi ship became famous, and successively received orders from all over the country for dozens of ships, subject to the width and draft of the downstream river channel along the Yongxing River to Beihai County, it was difficult for the Wanshi ship to pass above, and it was imperative to move part of the shipbuilding industry to the harbor.

To this end, Bailiyan distributed part of Yongxing's economic industries such as shipbuilding, winemaking, sauce making, coconut oil, spice planting, tea, wood processing, spinning and textile, primary leather processing, and breeding to Guangxin, and allowed Beihai County to grow mulberry and silkworm spinning to expand the output of silk fabrics to meet the growing demand for commodities, and at the same time actively developed 20,000 stone-class sail warships on the basis of Wanshi ships to prepare for the formation of a navy.

The construction of Ruitian and Lincheng was carried out at the same time as the relocation of Yongxing industry, and it was originally intended to be presided over by Liu Dun and Zhao Ju father and son, but Liu Dun died in 642, Zhao Ju was very old, and his sons Zhao Le and Zhao Shengyuan served as county guards in Ganfu and Dekang, so they had to be led by Liu Zao, Liu Chuan and Sikong Nan, Zhao Anling, and Guan Longxiang.

The relocation work has affected Yongxing's income to some extent, so that the income has not increased but decreased in two years, and King Xian has summoned Bailiyan several times to discuss whether to move or not.

Bai Liyan was calm and clear about the stakes every time, and at the same time, in order to dispel King Xian's concerns, Bai Liyan had to make false accounts and fill in the accounts with part of the war reparations withheld that year.

Regarding this money, every money was invested in the Yongxing City industrial project, and every effort was more or less rewarded.

In 641, the Gang faction succeeded in copying two pumped steam engines captured by the Heavenly Ships, which were modified for mechanical transmission.

At the same time, there is also a non-variable speed pulley cutting lathe, which was greatly improved in the year of finalized mass production, and redesigned to make a high-power general-purpose industrial boiler steam engine, and the lathe is derived from a single model of varieties and derived from four types of mature products.

And successively produced milling, punching, drilling, planing, cylindrical grinding, surface grinding, spinning machine and other gearboxless metal cutting row processing machines, and solved the spring, ball, bearing, gear, measuring tool standard, syringe needle, etc., a series of supporting parts process production.

More detailed and strict mechanical standards were formulated, and trapezoidal threaded rods were made by hand in 643, laying the foundation for the production of threading machines, and the era of fasteners represented by threads arrived.

The smelting of platinum-based nickel-iron alloys was much more difficult than expected, and it took eight years from the beginning of 637 to 644, which consumed countless material and financial resources.

During the period, thanks to the development of the chemical industry, and considering that the technical span is too large, Bailiyan took the initiative to reduce some indicators and added some copper to the ingredients to reconcile the properties between the elements.

As a result, platinum-based copper-nickel-iron-based alloy steel was smelted by mistake, which was baked in 644, and after half a year of physical and mechanical testing, it was not until Shengyuan 645 that the formal finalization grade was put into production.

After getting the first batch of qualified alloys in 644, the domestic financial situation has been greatly eased, the newly occupied land began to collect taxes, and the people's livelihood has greatly improved, so in the same year, high-manganese steel and tool steel were smelted, and tungsten acid was used as the main raw material to refine high-speed steel to solve the problem of general cutting tools and tool materials.

Due to the poor machinability of industrial diamonds, they are only suitable for ordinary simple forming tools, which limits their use environment, and the development of chip steel alloyed with tungstic acid and manganese is imminent.

In the autumn of 644, the industrial adjustment of Yongxing was basically completed, and the relocation and resettlement cost more than 1.8 million new dollars, more than 200,000 yuan of silver, and more than 2.7 million stones of grain and grass, and the resettlement of technicians and population was carried out in an orderly manner.

In the spring of 645, Ruitian fully resumed production and put into operation the latest improved textile machines, and two other experimental steam textile machines were put into use, which greatly increased the production capacity, and the pharmaceutical factory began to produce iodinephor, aspirin, Lexian anesthetics and chemicals in batches for clinical treatment.

At the same time, the Lincheng Chemical Industry Workshop was put into use in the spring of 644, and the three generations of Liu Zao, Liu Chuan, and Liu Deming's ancestors and grandchildren were transferred to Lincheng Engineering and Manufacturing Officials, and the Governor Chemical Industry strictly kept secrets.

Lincheng Chemical Industry Workshop produces nearly 100 kinds of chemical agents and explosives, including sulfuric acid, hydrochloric acid, nitric acid, caustic soda, aqua regia, ether, acetyl, tungstic acid, iodide, chemicals, etc., including conventional chemicals.

In addition, papermaking, cement and other workshops that pollute water sources are moved from Yongxing to the seaside for sewage discharge, and a small oil refinery is built to refine kerosene, diesel, gasoline and chemicals to meet basic industrial needs, and at the same time accumulate experience for the establishment of large-scale oil refineries and petrochemical plants in the future.

The resulting heavy oil and bitumen can only be accumulated in wooden barrels for later extraction of by-products such as wax, petroleum jelly, industrial rubber, pharmaceuticals, etc.

Regarding oil, after the destruction of the Black Turban, its oil production area in Lingjiang County fell into the hands of the Gongliang clan, and King Zhi directly incorporated the oil fields into the jurisdiction of the national treasury, turning them into foreign trade goods that Zhiguo made money from, and the oil of Xianguo came from Zhiguo.

Bailiyan had ordered the Ligong to send a master to explore the whole country, of course, due to his lack of experience, this kind of exploration was at best a blind cat touching a dead mouse.

Therefore, it was not until four years later that a shallow oil field was identified in the Luhou site, which was the same as the oil field accidentally discovered during the blasting of Qiubigon Mountain, which was shallow oil, but at a deeper depth.

The discovery of this oil field was also a fluke and an accident, purely due to the construction of local water conservancy projects, and the excavation of river ponds to dig up oil.

In order to raise gold and silver, they searched for the tomb to dig up, and dug up the "black spring" when they robbed the tomb in Lingjiang, and found that it was combustible and inexhaustible, and soon put it into the war.
