Problems solved by technology

However, as a monofluorinated halogenated hydrocarbon, HFC-161 is less stable than difluorinated or polyfluorinated halogenated hydrocarbons due to its own chemical structure, and it is easy to decompose at high temperatures above 175 ° C. The reliability and service life of the system, so it is necessary to add a suitable stabilizer to ensure its stability at high temperature, so as to make full use of the excellent performance of HFC-161, expand the application field, and play an active role in reducing climate change
There is no stabilizer report applicable to HFC-161 in the prior art

Abstract

The invention discloses a stabilizer composition suitable for HFC-161 and HFC-161 mixed working medium. The stabilizer composition is composed of two ingredients; a first ingredient is a combination material comprising one, two, or more than three selected from 4-methoxyphenol, 2-hydroxy-4-methoxybenzophenone, 4-tert-butylcatechol, 2, 2-bis(4-Hydroxyphenyl)propane and benzophenone; and the second ingredient is diethylene glycol dimethyl ether and / or 2-(2-Methoxyethoxy)ethanol. The stabilizer composition is capable of ensuring that HFC-161 cycled in a refrigerating system is not decomposed at a high temperature of 175 DEG C.

Description

technical field [0001] The invention relates to a stabilizer composition, in particular to a stabilizer composition suitable for refrigeration systems containing HFC-161. Background technique [0002] HCFC-22 has become the most widely used refrigerant with the best comprehensive performance in the refrigeration and air-conditioning industry at home and abroad due to its excellent physical, chemical and thermodynamic properties as well as good use safety and economy. However, HCFC-22 has a relatively high GWP (Global Warming Potential) value and ODP (Ozone Depletion Potential) value are not friendly to the environment and are required to be phased out within a time limit. For the substitute of R22, not only the environmental performance of zero ODP and low GWP is required, but also the performance similar to it is required, and HFC-161 is one of the ideal R22 substitutes at present. The ODP value of HFC-161 is zero and the GWP value is 12. It not only has excellent envir...
