BLENDED POLYOL ESTER LUBRICANTS FOR REFRIGERANT HEAT TRANSFER FLUIDS

摘要

From not more than three blending stocks, it is possible to prepare a widevariety of mixtures of esters of hindered polyhy-dric alcohols that are especially valuable lubricants for chlorine-freefluorocarbon refrigerant heat transfer fluids, particularlyRefrigerant 134a (1,1,1,2-tetrafluoroethane).
