Polyglycol lubricants for refrigeration compressors and process for preparing the same. |
摘要 |
<p>A refrigeration fluid compositions for compression refrigeration which have an upper solution critical temperature equal to or greater than 60 DEG C are composed of (A) selected hydrochlorofluorocarbons and hydrofluorocarbons and (B) polyether polyols having viscosities of greater than 80 centistokes (8 x 10<-><5> m<2>/s) at 38 DEG 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.</p> |
