The use of phosphorus trichloride

1. As a dopant in semiconductor production and a raw material for high-purity phosphorus production. In the manufacturing process of circuits, the quality of phosphorus trichloride is a key factor affecting pollution control and improving the yield of integrated circuits.

2. Mainly used for the production of organic phosphorus insecticides such as trichlorfon, dichlorvos, methamidophos, methamidophos, and rice blast. It is also a raw material for the production of trichlorophosphorus, phosphorus oxychloride, phosphite, triphenyl phosphate, and triphenyl phosphate.

3. In the pharmaceutical industry, it is mainly used to manufacture intermediates such as sulfadiazine and sulfamethoxazole.

4. Used as a shrinkage agent in the dye industry to produce naphthol dyes. It can also be used as a chlorinating agent and catalyst in seasoning manufacturing.

5. Phosphorus trichloride is a chlorinated reagent that can react strongly with compounds such as oxygen, nitrogen, sulfur, and dienes. It can also react with organic metal compounds and metal salts, and can also react with organic metal compounds and metal salts, making it a phosphorus source for synthesizing phosphorus containing metal ligands.

6. Phosphorus trichloride can be used as a raw material in lithium hexafluorophosphate in the field of new energy batteries.
