    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.
