"I discovered a brand new nitro dye. As Tom spoke, he pulled out a small glass beaker with some yellow powder lying in it.

"Ever since you asked me to study synthetic dyes, I've wanted to collect all the synthetic dyes that exist in the world. In addition to what you said, aniline violet for the British royal family, I just got a nitro yellow dye recently, which is trinitrophenol, which is not as famous as aniline violet, but in the field of silk dyeing, there has been a large-scale application.

After getting the trinitrophenol sample, I wanted to see how my preparation differed from the sample. I tried to synthesize trinitrophenol.

But......

The synthesis of trinitrophenol requires the product of coal chemical industry. In Europe, the coal chemical industry is very mature, but here, I can't buy coal chemical products in large quantities, so even if the test is successful, it will not be able to produce it on a large scale in the future.

So, I tried to replace it with petrochemicals.

I did it!

The yellow dye in my hand now is trinitrotoluene, and you see it looks very similar to this trinitrophenol trait!"

Doug looked at the two yellow powders of similar colors, and silently took another half step back, even though he knew that it was useless, and if either of these two things exploded, he would be affected if he took another ten steps back.

The trinitrophenol that Tom searched for had been chemically produced in the seventies of the last century, in 1771.

It is yellow crystals, bitter in taste, and soluble in water.

However, after the successful preparation, it has not been applied to the field of dyeing.

It was not until 1856 that aniline violet was accidentally mixed with potassium dichromate into aniline sulfate by a graduate student of the Royal College of Chemistry in the United Kingdom when he was trying to synthesize cinchona cream, a special antimalarial drug, quinine.

As a result, a charred black residue appeared in the flask.

By this point, the graduate student already knew that he had failed.

When washing the flask, he felt that the black substance was organic and should not be soluble in water, and it was difficult to wash it with water, so he poured alcohol into the flask to wash it.

However, when the alcohol was poured in, the asphalt-like black residue suddenly dissolved into a striking purple color by the alcohol.

After that, this purple synthetic dye was valued by the royal family and became the exclusive color of the royal family.

This graduate student also established an aniline violet synthetic dye factory and reaped a huge fortune.

Other businessmen, seeing the huge market of aniline purple, were also ready to move.

However, the patent of aniline violet is in the hands of graduate students, and it will take 20 years to wait for it to expire.

However, if they are allowed to develop synthetic dyes on their own, they feel that it is not worth paying so much cost, and it is not necessarily rewarding.

However, the clever businessmen still thought of a new way to take advantage of it.

If you find all the compounds that have been documented in the past and test them, there must be compounds that can be used as synthetic dyes.

In this way, trinitrophenol, which was tested in 1771, was turned out by merchants in 1856 after the success of aniline violet and became a yellow synthetic dye.

Now, three years have passed, and the number of compounds that have been excavated has been quite large.

However, these compounds are not suitable for large-scale staining applications due to various problems.

The azo dyes prepared by Tom under Doug's induction are already in the field of synthetic dyes, and they are relatively mature synthetic dyes in the later stage.

However, this is something that Doug knows. For Tom, it was with the contrast that he could understand the superiority of azo dyes.

However, no matter how he compared, Doug didn't expect that he would suddenly compare to nitro.

The term "trinitrophenol" sounds a bit unfamiliar, but its other name, "picric", is more well-known.

In the history of another world, picric acid was synthesized by humans in 1771, to entering the field of dyes in 1856, and then in 1871, a new worker in a French dye workshop could not open the barrel of picric acid, and smashed it with a hammer, causing an explosion and killing many people.

The owner of the dye workshop discovered that picric acid was actually an explosive.

Trinitrotoluene, which is very similar in structure to picric acid, is another explosive that is more well-known than picric acid - TNT.

The reason why Doug stepped back was because he was scared to see that these two explosives were in Tom's hands.

However, picric acid and TNT are safe explosives compared to nitroglycerin, which is also yellow.

Nitroglycerin is an explosive that will explode if the vibration received during transportation is slightly larger.

Picric acid was used as fuel for so many years, until the workers used a hammer to explode, compared to nitroglycerin, it is already very safe.

TNT is a good baby that won't explode even if a bullet passes through.

Even, TNT, which will only explode at the boiling point of 240 degrees Celsius, is directly heated in a boiling pot with water until it melts, and as a plastic explosive, it is poured into the cracks of the stone, and then detonated after solidification.

However, safety is safe, and Doug still has little confidence in Tom.

Tom was a little tired from all this, and his voice was a little hoarse, but even though his voice was hoarse, he said excitedly.

"Do you know that the trinitrotoluene I prepared can actually explode? It's just a small bit, and it explodes on fire, oh my God!" Tom didn't know when the tweezers appeared in his hand, and he used the tip of the tweezers to pick up a little bit of trinitrotoluene, and showed it to Doug.

Doug didn't know if Tom was going to die with a trinitrotoluene like he was now.

It would be a miracle that this was the case that he could survive and his arm intact.

Tom seemed to know Doug's thoughts, and he smiled and said, "How could I try it myself! I let my assistant try it......! He's already blown up an arm!

But what is an arm?

All he's lost is an arm!

What we got was a whole new kind of explosives!

Doug!

Doug!

Aren't you happy too?"

"I ...... It's a lot of fun. Doug reluctantly admitted that he was happy, but he still reminded, "Don't roast it on the fire if it's bitter." ”

"What did you say?" asked Tom's ear, not knowing if it was deaf from the explosion.

"I said, don't put the bitter sour on the fire!"

"Oh oh, you said bitter sour shouldn't be baked? I'm sorry, it's late. Tom bowed his head in shame.

"What are you ......" Before Doug could finish speaking, he heard a "bang!" from the forest behind the hut.

The smoke of gunpowder slowly rose in the forest, and gradually ignited the fire, roasting the dry forest.

"Looks like we're going to be on fire......" Doug spread his hands helplessly.
