Phosphorus oxychloride

Mô tả

ỨNG DỤNG

Used as a semiconductor dopant, and a raw material for optical fibers.

Widely used in the production of pesticides, pharmaceuticals, dyes, phosphate flame retardants. Raw materials of  manufacturing organophosphorus pesticides herbicides, chlordimeform. Used in the production of plastic plasticizer. Also used in the chlorination of the long-acting sulfa drugs, the production of dyes intermediates, organic synthesis chlorinating agent and catalyst, uranium extraction agent.

The raw material for manufacture of organophosphorus pesticide chlordimeform. For the production of diphenyl - iso-octyl phosphate, and triethyl phosphate and the production of plastic plasticizer. For the chlorination reaction of the long-acting sulfa drugs. Production of dye intermediates, organic synthesis chlorinating agent and catalyst, uranium extraction agent.

Mainly used for synthesis of another type of phosphorus-containing intermediates - the phosphorus oxychloride or phosphorus acid dichloride, such as a synthetic O, O-diethyl-phosphoryl chloride, in the synthesis of organophosphorus pesticides, and then the synthetic pesticides ethylthio ring, naphthalene, or syntheticO-ethyl dichloride, thus the synthetic pesticides Ethoprophos.

In other aspects, the phosphorus oxychloride can be used as the chlorinating agent, catalyst, plasticizer, dye intermediates. Also used in the pharmaceutical industry and organic synthesis.
