Chapter 781 Mysterious Reagent No. 17
Since it is a research and development project for new gunpowder, it must have nothing to do with optical lenses. Ao Fei was disappointed.
However, it is not boring to have such a new junior. If these researchers do not have specific project research and development tasks issued by Luo Chong, they will spend most of their time doing research on their own, and then compile the research results into a book, and finally submit it to Luo Chong for approval, which may be added to the new textbook.
This is also what Luo Chong often says about scientific exploration. In addition, it is also a way for him to be lazy and inspire his tribesmen to explore on their own.
If we say that the busiest group in the entire Huxin Island Research Institute is currently, it may be the rubber group and the chemical group. Luo Chong brought a lot of things from the Tang tribe before, and they were all to be handed over to them for analysis and testing. Many of the Tang tribe’s ores were limited by the conditions of Takumi County at the time, and could only be tested by simple calcination tests, and all the components and performance could not be measured.
These two groups are busy with these things now, but since Luo Chong has given them a new task, they naturally cannot refuse.
The researchers in the chemistry group are also very young. Most of the researchers in this new subject are young people, all of them are top science students in the school, because those liberal arts students who like to study Han law have become officials, and the handicraft field is concentrated with a large number of older craftsmen and artisans.
At the beginning of the second day, Qubing, accompanied by his senior in the chemistry group, held a group meeting. Wen Nong, a person in charge who graduated from the Liuyang County campus, presided over the work allocation. Qubing mainly explained the leader's requirements.
"This time, the leader wants us to develop ammunition for several weapons, which are divided into two parts: gunpowder and projectile. Our chemistry group is mainly responsible for the development of gunpowder. The leader has given the production method of colloid double-base propellant. We just need to be careful when we try to produce it.
The other thing is the production of three highly sensitive explosives. The information says that if too much pressure is applied, such as a collision, it will explode. So before the project starts, I still want to remind everyone to be careful and be careful, and be sure to strictly abide by the laboratory rules and regulations.
This time we are divided into five two-person teams, one of which is responsible for making guncotton, one is responsible for purifying ether, and the other three are responsible for a highly sensitive explosive. Medicine, we still follow the old rules, one old person guides one new person, and the new person is responsible for assisting.
I will distribute the information to you in a while, whoever is interested can do it, and the rest of the chemistry group will continue to analyze Reagent No. 17 with me. Reagent No. 17 has many functions, and we must try our best to dig out all its uses
. Okay, that's it for the meeting, everyone will look at the information and then divide into groups. "After Wen Nong looked at the information brought by Qu Bing, he quickly handed over the new project. Qu Bing was curious at this time. What exactly is Reagent No. 17? Even though the leader handed over the new project, they still insisted on researching it, so he asked Wen Nong beside him.
Wen Nong did not hide it. Speaking of Reagent No. 17, he was still very proud, because the identification of the properties of this new substance was determined by him against all odds, and he completed the experiment alone to prove his judgment to others.
"Reagent No. 17 is a new type of metal mineral that the chief brought back from the Tang tribe. However, since we have not been able to reduce it to a single metal substance and have not yet completed the identification of its properties and the exploration of its uses, we have not reported it to the chief and have not given it a name. It is still called Reagent No. 17 for the time being."
Wen Nong introduced it to Qubing while leading him to the laboratory and placing a bottle of white fine powder in front of him.
However, Qubing was confused. This thing was very white, like flour, but people said it was a metal mineral, so it could not be flour.
"Brother Wen, this thing is clearly white stone powder. Since you can't reduce it to a single metal, how can you be sure that it is a metal? Can't it be lime or gypsum?" Qubing asked in confusion.
"Haha, you are right. The leader has a famous saying that we should make bold assumptions and verify them carefully. At first, we also suspected that it was calcium carbonate, that is, limestone, but it is not. After calcination, this mineral does have similar alkalinity, but not as high as quicklime.
Then we mixed it with charcoal and calcined it, but it didn't reduce the metal. Then we used sulfuric acid to experiment, and the result was what you see in front of you. The current state of this thing is actually a metal sulfate. Of course, we didn't know it at the beginning. It was only when I used the flame color reaction experiment that I proved that it was actually a metal, and it was a metal we had never seen before." Wen Nong said with a smile.
"Flame color reaction, what is that?" Qubing immediately became curious.
"When different metal salts are burned by flames, they will emit flames of different colors. For example, the table salt we eat, the leader said it is sodium chloride, which is also a metal compound. When the table salt is ignited, it will emit bright yellow flames.
And the sulfate in front of you will emit green flames after being ignited. Isn't it amazing?"
Qubing was stunned when he heard it. Metals can emit flames of different colors when they are ignited. Chemistry is really amazing.
"Then Brother Wen, if we can't restore it to its original metal element, can we still use it?" Qubing asked again.
"Of course, some metals are not necessarily better than steel, but their compounds are more valuable. We have already developed a lot of practical value for this sulfate.
You see it is very white, right? We thought about whether we could use it as a dye, and it really works. Not only can it be used to dye white cloth, but more importantly, it can be used to dye rubber and make white rubber.
Moreover, this thing will glow when it is calcined. I also asked the optical team to help analyze it. They said that it is not luminous, but light caused by reflection. When there is strong light shining on it, it will also reflect very obvious light. So we also made it into luminous paint to apply on some important night The paints are also very eye-catching when exposed to moonlight at night.
This thing is also low-toxic and has a killing effect on several field pests. It can be diluted with water and sprayed on crops to kill insects. It has so many uses.
We have also discovered its extinction effect. This thing can inhibit many chemical reagents with photosensitive properties. A lot of experiments are still being conducted to verify it. "
Qubing was stunned. He didn't expect that just a metal sulfate that could not be reduced could have so many important uses. Thinking about the explosives that he was about to study that would automatically ignite when touched, this chemistry was simply too magical!
