Chapter 74： Magic saltpeter, in exchange for intelligence! (1/2)
【Saltpeter (Excellent)】
Description: The high-purity saltpeter purified by the entry-level craftsman ”Suma” has a wide range of functions. It can be used to make matches, pyrotechnic powder, black powder, glass and food preservatives, etc., because of inexplicable reasons, the grade is Upgraded to a sophisticated level.
Special ability: make nitric acid (concentration (95%↑)
made into gunpowder (energy +50%)
made into fertilizer (fertility +25%)
...
Evaluation: There are many uses, a wide range, and quick results! Just hang up? (Righteous words!)
The property page that popped up from the system was refreshed by the special ability of Saltpeter for the first time.
has more than 30 uses in various aspects, all of which have been strengthened to a certain extent.
But this is not what surprised Somo the most.
”It turns out that the Nether Energy Water mixed with these things will produce so many changes?”
fiddling with the saltpeter in the beaker in surprise, Somo still couldn't see how this thing had so many characteristics.
”but...”
”If the system is so powerful, I'm afraid my technology tree will skyrocket!”
Staring at the saltpetre powder with scorching eyes, Somo's thoughts have drifted to the oil machine well in Refuge No. 2.
Originally, after this wave of purified saltpeter and sulfur, mixed with charcoal, the famous black powder can be produced directly into the age of firearms.
But now, an abrupt term popped up in Somo's mind-
”Bitter taste sour!”
As the famous ”Yellow Explosive” (TNP), it is also called ”Piric Acid Explosive”.
Its ingredient is ”trinitrophenol”, which is often confused with Nobel's ”safe explosive”, ”TNT”.
In 1771, the British Peter Wolfe synthesized a dye.
He mixed concentrated sulfuric acid, nitric acid and phenol (maybe refined from coal tar crude phenol or indigo, people didn’t know phenol at the time) to obtain a bright yellow crystalline powder with a strong bitter taste. Given the name ”picric acid”.
People at that time just dyed clothes and made paint with bitter acid.
In the dye industry at that time, the name of trinitrophenol was often ”yellow”. People have dyed fabrics with a bitter taste for 100 years, but they never thought about how to blow it up.
In 1871, the guys in a dye shop in Paris, France encountered a problem. There was a backlog of yellow dye tanks that seemed to be rusted to death and couldn’t be unscrewed anyway. So the desperate guys decided to open the tank in the simplest and rude way— —Smash!
And the hammersmith I found was a big hammer for 80 yuan.
This time, the hammersmith Mou had enough strength to go down with a hammer!
Unexpectedly, the jar exploded with a ”boom”, and the entire dyeing workshop suddenly took a plane, leaving only a group of colorful survivors moaning in the ruins.
After many investigations, people ruled out the unidentified explosives hidden in the jar, and locked the problem to the picric sour jar. People suddenly realized that--
”The yellow paint was detonated by a hammer!!!”
This incident caused a sensation in society, and people were worried about the ”yellow color”.
But the French military at the time was bright. It was clearly the best military weapon sent from the sky. The ”yellow color” proved its safety in long-term use, and it can also be easily prepared on a large scale.
Then the French ”Eugene Turpin” took the lead in developing the ”picric acid press-in method” of artillery shells, and also gave it the name ”melinite”, that is, ”melinite”.
The term is unfamiliar to many people, but when it comes to the 1897 75mm field gun, everyone is familiar with it, which is Li Yunlong’s ”Italian gun”
Now there is saltpeter to make nitric acid, and sulfur and saltpeter can react to form sulfuric acid, and then some petroleum can be used to extract the toluene inside...
”If it is really possible, I am afraid that my bomb technology tree will directly go beyond the black powder and nitro collodion, and directly come to the era of yellow explosives!”
Thinking about the explosive configuration methods that the old man had been talking about before coming, Somo was instantly excited.
Black gunpowder is only a propellant. When made into a gunpowder bag, it can only complete the two processes of deflagration and ignition.
Picric acid is different. Once a shock wave with a chemical reaction is detonated, an explosive reaction occurs first at the point of initiation to generate a large amount of high temperature, high pressure and high speed airflow, which excites the shock wave in the explosive.
The shock wave strongly compresses the adjacent thin layer of explosive to cause the explosive reaction, which generates a large amount of gas and a large amount of heat, and completes the detonation-detonation-wave process.
Even if it can accumulate enough bitter sour, it can be made into explosive packs and thrown into the kobold castle.
Under the detonation wave, as long as one back and forth, you can let the kobolds know what justice is from heaven!
”I will try to repair the oil well tomorrow!”
In front of the workbench, Somo stood up and sat down again and again, his heart agitated hard to calm down.
Pour the purified 500g saltpeter powder into a wooden container and put it in the second bedroom. Somo returned to the workbench again.
”I know the equation for purifying yellow explosives. I have learned the methods of preparing nitric acid and sulfuric acid in high school. These are not problems. The key lies in the extraction of toluene in petroleum and the process of mixing reaction to produce picric acid..”
”In the past, Nobel made explosives and killed his brother. Although this picric acid is not as difficult as nitroglycerin, it may explode when it encounters high temperature, friction, or impact. Moreover, it reacts with iron and acts like thunder. Acid mercury generates mercury salt like picric acid metal salt, causing accidental explosion hazard.”
