Unsaturated polyol esters used in hydraulic fluid applications
View Patent ↗This invention relates to unsaturated polyol esters that can be used in hydraulic fluid applications, including fire-resistant hydraulic fluid applications, marine hydraulic fluid applications, metalworking fluid applications, food grade fluid applications, and transformer fluid applications, and methods for making the same.
1. An unsaturated polyol ester composition comprising a compound of the following structure:
wherein R is (CH 2 ) 7 CH═CH 2 or (CH 2 ) 7 CH═CHCH 3 .
2. The unsaturated polyol ester composition of claim 1 , wherein the composition is a hydraulic fluid.
3. The unsaturated polyol ester composition of claim 1 , wherein R is (CH 2 ) 7 CH═CH 2 .
4. The unsaturated polyol ester composition of claim 1 , wherein R is (CH 2 ) 7 CH═CHCH 3 .
5. An unsaturated polyol ester composition comprising a compound of the following structure:
wherein R is an unsaturated C9 linear alkyl group, and each R 1 is independently the hydrocarbyl moiety of a C3 to C35 linear or branched saturated fatty acid selected from the group consisting of isononanoic acid, neodecanoic acid, 2-ethylhexanoic acid, caproic acid, and caprylic acid.
6. The unsaturated polyol ester composition of claim 5 , wherein R is (CH 2 ) 7 —CH═CH 2 .
