HCFC124 General Properties

General properties of HCFCs

Physical and Chemical data can be found on producers websites HCFC-22 (chloro-difluoro-methane)

Introduction

Chlorodifluoromethane is a non-flammable, colourless and nearly odourless gas under normal conditions. A large proportion is used as a chemical intermediate and therefore not emitted into the atmosphere. Other important uses are in refrigeration and in air conditioning systems; with present practice, most of the chlorodifluoromethane so used will eventually be emitted into the atmosphere.

Its moderate water solubility and low octanol/water partition coefficient indicate a negligible bioaccumulation potential. Contamination of water and food would not be expected from its physical and chemical properties and has not been reported.
