POLYESTER LUBRICANT FOR WORKING FLUIDS COMPRISING DIFLUOROMETHANE |
摘要 |
<p>Mixtures of select neopentyl polyol esters are found to be highly miscible with the refrigerant R-32 over a wide temperature range. Working fluids are provided comprising R-32 and a lubricant containing these select neopentyl polyol esters and having a kinematic viscosity at 40° C. of 32 cSt or higher. Specifically, the lubricant composition of the invention comprises a mixture of alkylcarboxy esters of neopentyl polyols, wherein at least 10 wt % of all neopentyl polyol esters are esters of pentaerythritol oligomers of 4 or more pentaerythritol monomer groups, and wherein a majority of the alkylcarboxylate groups of the alkylcarboxy esters of neopentyl polyols are pentanoyl groups wherein at least 15% of the pentanoyl groups are branched.</p> |
