CARBON DIOXIDE-BASED WORKING FLUIDS FOR REFRIGERATION AND AIR CONDITIONING SYSTEMS |
摘要 |
A working fluid comprising (a) a refrigerant comprising carbon dioxide and (b) a poly(neopentylpolyol)ester composition produced by reacting a neopentylpolyol having the formula: wherein each R is independently selected from the group consisting of CH3, C2H5 and CH2OH and n is a number from 1 to 4, with at least one monocarboxylic acid having 2 to 15 carbon atoms in the presence of an acid catalyst and at a mole ratio of carboxyl groups to hydroxyl groups of less than 1:1 to form a partially esterified composition. The partially esterified poly(neopentyl)polyol composition is then reacted with additional monocarboxylic acid having 2 to 15 carbon atoms to form a final poly(neopentylpolyol)ester composition. |
