Abstract:
1278953 Polyesters UNILEVER-EMERY NV 12 Aug 1969 [14 Aug 1968] 40284/69 Heading C3R [Also in Division C5] A thickener for lubricants is made by reacting a polymerized oleic acid with neopentyl glycol and propylene glycol. When the acid value of the ester formed is 11À2 it is heated with the glycidyl ester of a neo-acid in excess of the amount required to react with the free acid contained in the thickener; the excess of the glycidyl ester is then removed from the thickener under vacuum.
Abstract:
Residues resulting from the distillation of fatty acids obtained from fat-splitting processes are converted by the process of this invention to useful metal working lubricants. The present process utilizes distillation residues, which are typically viscous oils ranging in color from dark brown to black and which heretofore had little or no commercial value and were burned or otherwise disposed of, to produce lubricants having performance characteristics which make them suitable for use in continuous metal-casting and other metal working operations.
