Abstract:
Ester lubricants derived from high molecular weight dibasic acids, polyoxyalkylene glycols and monofunctional aliphatic alcohols are provided. These ester compositions are useful as lubricants and are readily emulsifiable with water. Aqueous emulsions of these esters have superior lubricating and rust inhibiting properties.

Abstract:
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.
Abstract:
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.
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.
Abstract:
INTERNALLY FLEXIBILIZED PHENOL-FORMALDEHYDE RESINS ARE PREPARED FROM FORMALDEHYDE, PHENOL AND A PHENOLATED OIL OBTAINED BY REACTING AN EXCESS OF A PHENOLIC COMPOUND WITH A NON-CONJUGATED, UNSATURATED OIL IN THE PRESENCE OF AN ACTIVE CLAY CATALYST, THE CATALYST OPTIONALLY CONTAINING A MINOR AMOUNT OF A MINERAL ACID.

Abstract:
An aqueous process for the recovery of polymeric fatty acids from crystalline clay minerals including catalyst and bleaching clays is provided. The process involves contacting the clay containing the polymeric acid with a sufficient quantity of water and agitating to displace the polymeric acid, and when the displacement is essentially complete, recovering the polymeric fatty acid from the water and clay. An additional feature of this invention is the reuse of the clay for catalyst or bleaching purposes.
Abstract:
POYAMIDE RESINS EXHIBITING IMPROVED FREEZE-THAW CHARACTERISTICS IN PRINTING INK COMPOSITIONS COMPRISE THE REACTION PRODUCT OF A DIAMINE WITH A SELECTED MIXTURE OF CARBOXYLIC ACIDS COMPRISING FROM ABOUT 20 TO 90 EQUIVALENT PERCENT OF A POLYMERIC CARBOXYLIC ACID HAVING AN ACID FUNCTIONALITY OF AT LEAST 3; FROM ABOUT 10 TO 80 EQUIVALENT PERCENT OF A POLYMERIC CARBOXYLIC ACID HAVING AN ACID FUNCTIONALITY OF ABOUT 2; IN A RATIO OF THE FORMER POLYMERIC CARBOXYLIC ACID TO THE LATTER POLYMERIC CARBOXYLIC ACID OF FROM ABOUT 1:4 TO 9:1; AND FROM ABOUT 10 TO 60 EQUIVALENT PERCENT OF A CHAIN-STOPPING MONOCARBOXYLIC ACID.
