POLYGLYCOL LUBRICANTS FOR REFRIGERATION COMPRESSORS AND PROCESS FOR PREPARING THE SAME

摘要

A refrigeration fluid compositions for compression refrigeration which have an upper solution critical temperature equal to or greater than 60.degree.C are composed of (A) selected hydrochlorofluorocarbons and hydrofluorocarbons and (B) polyether polyols having viscosities of greater than 80 centistokes (8 x 10-5 m2/s) at 38.degree.C and having a number average molecular weight of from 400 to 2000 wherein the polyols are the residue of an active hydrogen compound such as glycerine or ethylene diamine. 37,276A-F
