Abstract
High viscosity functional fluids prepared by reacting a polyglycerol with a triglyceride oil or fat. The reaction products can be used as high viscosity lubricants or blended with triglyceride-based functional fluids for use in mud drilling, as low temperature lubricants, cutting fluids, hydraulic fluids, and food grade lubricants.
Claims16
A method for lubricating the moving parts of a mechanical device which comprises applying to said moving parts a polyglycerol ester which is the reaction product of a polyglycerol containing three or more glycerol monomers and a member selected from the group consisting of a fatty acid, methyl esters thereof, a triglyceride and methyl esters thereof;
- said reaction product having a saponification value of between 100 and 169.
A method for lubricating the moving parts of a mechanical device which comprises applying to said moving parts a blend of
- i) a polyglycerol ester which is the reaction product of a triglyceride or a fatty acid and a polyglycerol containing three or more glycerol monomers and the reaction product has a saponification value of between 99 and 181, and
- ii) a triglyceride based functional fluid in which the triglyceride of ii) may be the same or different than the triglyceride of the reaction product of i).
