摘要:
Water soluble mixed ester lubricants derived from triglycerides are obtained by transesterifying a triglyceride with a low molecular weight polyoxyethylene glycol in the presence of shortchain mono- or dicarboxylic acids. The mixed ester compositions of this invention are readily water soluble and are excellent lubricants for metalworking operations. Water solubility is achieved with the present mixed ester products even though they have higher triglyceride contents than previously known ester lubricants.
摘要:
Ester lubricant compositions are provided which provide a good balance of lubricity and emulsifiability. The esters are derived from polyoxyalkylene glycols with a dibasic acid mixture consisting of dimer acids and short-chain dibasic acids. The emulsions are clear, homogeneous lubricant solutions provide excellent spin finishes for fibers such as polyamides and polyesters.

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.
