1,1-dichloro-1-fluoroethane is a chemical compound from the group of saturated halogenated hydrocarbons .

Extraction and presentation

1,1-Dichloro-1-fluoroethane can be obtained by fluorinating 1,1,1-trichloroethane with anhydrous hydrogen fluoride at 144 ° C, whereby 1-chloro-1,1-difluoroethane is also formed.

1,1-dichloro-1-fluoroethane is one of the chemical substances that are produced in large quantities (" High Production Volume Chemical ", HPVC) and for which the Organization for Economic Cooperation and Development (OECD) collects data on possible dangers (" Screening Information Dataset ", SIDS) was prepared.

properties

1,1-dichloro-1-fluoroethane is a very volatile, colorless liquid with a slightly ethereal odor that is sparingly soluble in water. At temperatures above 200 ° C the compound decomposes, producing hydrogen fluoride, hydrogen chloride and phosgene . The compound has a global warming potential of 938 and an ozone depletion potential of 0.11.

use

1,1-dichloro-1-fluoroethane is used as a cleaning agent and for plastic foaming for PUR foams.
