  • Patent number: 6551524
    Abstract: A high quality lubricant for compressors operated during at least part of their compression cycle at temperatures above normal human comfort temperatures, such as most automotive air conditioners, especially those using chlorine free hydro-fluorocarbon refrigerant working fluids, is provided by mixed esters of hindered polyols, most desirably pentaerythritol, with a mixture of carboxylic acids including at least some iso-pentanoic acid along with one or more of iso-nonanoic acid, isooctanoic acid, and dibasic acids such as adipic. When the mixture includes about 7% adipic and amounts of branched C8-9 and C5 monobasic acids in a ratio of at least 0.75:1.00, the esters formed have excellent solubility for paraffinic and naphthenic mineral oils and are therefore especially well suited for lubricating vehicle air conditioners formerly containing chlorine containing heat transfer fluids and mineral oil lubricants.
