Usage

General Description

2-chloro-1-(chloromethoxy)-1,1,2-trifluoroethane, also known as HCFC-133a, is a chemical compound that is a member of the hydrochlorofluorocarbon (HCFC) family. It is used as a refrigerant and as a blowing agent in the production of foam insulation. HCFC-133a has a relatively low global warming potential compared to other HCFCs, and it is considered to be a less damaging alternative to chlorofluorocarbons (CFCs) and other ozone-depleting substances. However, HCFC-133a is still regulated under the Montreal Protocol due to its potential impact on the ozone layer, and efforts are underway to phase out its use in favor of more environmentally friendly alternatives.

RADICAL REDUCTION OF C-Cl BONDS IN CHLOROFLUORO ETHERS

Reduction of C-Cl bonds in 2,2-dichloro-1,1,2-trifluoroethyl trichloromethyl ether (I), 2-chloro-1,1,2-trifluoroethyl trichloromethyl ether (II), and 2,2-dichloro-1,1,2-trifluoroethyl dichloromethyl ether (III) with 2-propanol, 2-butanol, cyclohexanol, tetrahydrofuran, diethyl ether, and 1,3-dioxolane initiated photochemically and by radiation has been investigated.Beside the main reduction products - 2-chloro-1,1,2-trifluoroethyl dichloromethyl ether (IV) and 2-chloro-1,1,2-trifluoroethyl chloromethyl ether (V) - it was also possible to prove the formation of 1,2-dichloro-1,2-bis(2-chloro-1,1,2-trifluoroethoxyethane) (VI), 1-chloro-1,2-bis(2-chloro-1,1,2-trifluoroethoxy)ethene (VII), and 1,2-dichloro-1,2-bis(2-chloro-1,1,2-trifluoroethoxy)ethene (VIII).The structure of products was confirmed by elemental analysis, MS, IR, 1H NMR and 19F NMR spectra and by GLC comparison of the elution times with those of the standards.The relative reduction ability of the solvents used and the reduction rate order of C-Cl bonds in the compounds (CCl3 > CFCl2 > CHCl2 and CFClH) are given.
