    Abstract: The present invention provides a high-reliable hermetic compressor in which aggression to an organic material is low by using a refrigeration oil using, as a base oil, an alicyclic multivalent carboxylic acid ester compound and made of an alicyclic multivalent carboxylic acid ester compound having at least two ester groups, the at least two ester groups being bound to carbon atoms adjacent to each other on an alicyclic ring. The ratio of hydrocarbon radicals in which carbon number is 4 or less among hydrocarbon radicals bound to the at least two ester groups is 15% by weight or less.

    Abstract: A novel biodegradable polyneopentyl polyol (PNP) ester based synthetic ester basestock that includes a PNP ester admixed with a dicarboxylic acid ester coupling agent is provided. The PNP ester-coupling agent mixture is blended further with minor amounts of a single, or mixture of, additional high molecular weight linear or branched chain ester. The final basestocks are compatible with standard lubricant additive packages and miscible with gasoline to provide biodegradable lubricants that have improved viscosity characteristics, good low temperature properties, and improved lubricity for 2-stroke engine lubricant applications.
