Abstract

The invention discloses a composition containing HFC-161 and a stabilizer, wherein the stabilizer is selected from one or more of epoxy compound, nitro-compound, hindered amines, hindered phenols, secondary arylamines, beta-diketones, phosphite esters, salicylic acid esters, cinnamic acid esters, hydroxybenzophenones, hydroxybenzoic acids, hydroxylphenyl benzotriazoles, hydroxylphenyl triazines, oxanilides, formamidines, polyhydric alcohols, ortho-formates, organosulfur compounds, olefins, ethanol amines and fatty amines. The composition provided by the invention is capable of keeping a stable state in a long time under the coexistence of air or oxygen, and capable of being used as a heat transfer composition in the form of a liquid or a gas, a refrigerant, an aerosol propellant and the like.

Description

technical field [0001] The present invention relates to a composition comprising HFC-161 and a stabilizer. Background technique [0002] At present, the most widely used refrigerants with the best comprehensive performance in domestic and foreign refrigeration and air-conditioning industries are HCFC-22, HFC-125, HFC-134a, HFC-32, CFC-12, R-407C, R-410A and R -404A, etc., all have excellent physical, chemical and thermodynamic properties, as well as good use safety and economy. However, due to its high global warming potential (GWP) and ozone depletion potential (ODP), it is not friendly to the environment and is required to be phased out within a time limit. [0003] As a substitute for refrigerants such as HCFC-22, it is not only required to have zero ODP, low GWP environmental performance, but also to have similar performance, and HFC-161 is currently one of the ideal substitutes. [0004] HFC-161 is fluoroethane, molecular formula CH 3 CH 2 F, CAS registration number...
