Description

Chlorotrifluoroethane ( HCFC-142b)

HCFC-142b is a colorless gas under ordinarytemperature with slight fragrance, and a colorless & transparent liquidunder the pressure of itself, easily soluble in oil but poorly in water. It ismainly used in the refrigerating systems under high temperature conditions,thermostatic control switches, the intermediate of aerial propellant, and theimportant raw material for vinylidene fluoride.
