It is speculated that what you want to ask may be about the use of boron, arsenic and other element-related compounds. The following answer is in classical Chinese:
Boron, arsenic and their related compounds have a wide range of uses. Borax, in the metallurgical industry, can be used as a flux to make the melting of metals smoother, impurities are easy to remove, and the quality of metals is pure. In the chemical industry, it is also an important raw material for the manufacture of special glass and ceramics, which can increase its strength and heat resistance.
Arsenic compounds have certain uses in medicine in the past, such as in small amounts, or can treat certain diseases. However, arsenic is toxic and should be used with caution. In agriculture, arsenic-containing agents were once used as insecticides to remove pests and protect the growth of crops. However, due to their toxic residues, they have mostly been discarded today.
And dimercaptopropanol, dimercaptosuccinic acid, etc., are important antidotes. In case of metal poisoning, it can be combined with it to promote its excretion from the body, save people in danger, and be a good medicine for doctors to detoxify. In clinical first aid, it has extraordinary functions.

What are the precautions for the use of 1 '- (4-sulfonyl-1-naphthyl azo) -2' -hydroxy-6 ', 8' -naphthalene disulfonate trisodium salt?
The system of nitrate, disulfide and three charcoal is the secret of the gunpowder master. When using it, many matters cannot be ignored.
First, be careful with raw materials. Nitrate, sulfur and charcoal each have their own characteristics. Nitrate is dry, sulfur is flammable, and charcoal is also flammable. All three need to be properly placed away from fire sources, water sources and other things to prevent their qualitative changes and cause disasters. And the storage of each thing should be dry, ventilated, and protected from direct sunlight to ensure its qualitative stability.
Second, accurately weigh. The ratio of these three is related to the effectiveness of the medicine. The ratio of nitrate, sulfur and charcoal is completely different, or the power of the medicine is very different. The weighing tool must be accurate. When operating, be careful and not slack a little, so that the proportions of each object are in the fixed formula, so that the medicinal power can be obtained.
Third, mix carefully. When mixing, you need to do it gently, and do not stir vigorously to prevent friction from generating heat and causing it to break out. And the mixing place should be an open and empty place, surrounded by no flammable or explosive things, to prevent accidents. Mixed people must wear protective equipment, such as thick clothes, gloves, masks, etc., to ensure their own safety.
Fourth, store it properly. After making, keep it in a sealed container and place it in a cool and dry place. Keep away from crowded places, and do not coexist with other chemical substances to prevent interaction and cause danger.
Fifth, strictly abide by the procedures. When using, you must follow the established laws, and do not change the steps or increase or decrease the dose without authorization. Those who operate need to undergo professional training, understand and be familiar with the method. In case of emergencies, they can deal with it calmly, and ensure that everything goes smoothly and does not cause disaster.
All these things are important to pay attention to when using gunpowder. You must always remember that you must not ignore them in order to be safe.
What is the synthesis method of 1 '- (4-sulfonyl-1-naphthyl azo) -2' -hydroxy-6 ', 8' -naphthalene disulfonate trisodium salt?
To prepare 1%, 27- (4-hydroxymethyl-1-naphthyl methyl ether) - 2-naphthol-6,8-dihydroxybenzoate trimethyl ester, the synthesis method is as follows:
First take an appropriate amount of 4-hydroxymethyl-1-naphthyl methyl ether, add the matching reactants and catalysts in a suitable reaction vessel, and control the temperature, duration and other conditions of the reaction. This step aims to carry out specific chemical modifications to 4-hydroxymethyl-1-naphthyl methyl ether to make its structure change as expected, so as to obtain the intermediate required for subsequent reactions.
