摘要:
From not more than three blending stocks, it is possible to prepare a wide variety of mixtures of esters of hindered polyhydric alcohols that are especially valuable lubricants for chlorine-free fluorocarbon refrigerant heat transfer fluids, particularly Refrigerant 134a (1,1,1,2-tetrafluoroethane).
