摘要： A high viscosity synthetic ester base stock of about ISO 68 to 400 is formed from a neopentylpolyol condensed with at least one monocarboxylic acid selected from the group consisting of linear acids having between 4 to 10 carbon atoms and branched chain acids having from 5 to 10 carbon atoms in an excess of hydroxyl to carboxylic acid groups to form a partial polyneopentylpolyol ester that is further reacted with the same or similar acid to form a high viscosity polyneopentylpolyol ester. Lubricants formed from the base stocks have satisfactory miscibility with standard highly or fully fluorinated refrigeration fluids.

摘要： An improved additive package including at least a polymeric amine antioxidants and a borated extreme pressure/antiwear agent for a polyol ester lubricant suitable for use in high temperature applications is provided. The lubricant fluid includes a base stock that is the reaction product of a polyol and monocarboxylic acid mixture including a major proportion of 3,5,5-trimethylhexanoic acid (iso-C9 acid). The additive package may be added in up to about 20 percent by weight of the lubricant to provide a viscosity of the lubricant at 40° C. of at least about 140 cSt and at 100° C. of no less than about 15.0 cSt. Greases are formed by adding a thickener to a high viscosity lubricating fluid.
