Product Description
1. Molecular formula: POCl3
2. Molecular weight: 153.35
Three, physical and chemical properties:
Colorless transparent volatile liquid with strong pungent odor. It is easily hydrolyzed in humid air to produce phosphoric acid and hydrochloric acid. The melting point is 1.25°C, the boiling point is 102°C, and the relative density is 1.675. The heat of evaporation is 33.7kJ/mol. It is still very stable when it is close to 300°C. It explodes when encountering large amounts of water. Toxic and corrosive.
Four, use:
It is mainly used for the N-type doping of chips. It is a liquid phosphorus source for the production of integrated circuits, solar cells, optical fiber preforms, separation devices, etc. It is an electronic chemical necessary in the chip manufacturing process. At the same time, electronic grade phosphorus oxychloride is also highly manufactured. Raw material for pure phosphate ester.
