Claims20
A lubricating composition comprising a partial or half-ester of DIACID 1550 according to the structure:
- wherein the partial ester is derived from an esterification reaction at R1 or R2 with an alcohol selected from the group consisting of n-pentanol, 1-docecanol, 2-ethyl-1-hexanol, and combinations thereof, and wherein at least one of R1 or R2 but not both is H.
An aqueous metalworking composition comprising a metal working fluid and an effective amount of a DIACID 1550 partial ester according to the structure:
- wherein the partial ester is derived from an esterification reaction at R1 or R2 with an alcohol selected from the group consisting of n-pentanol, 1-docecanol, 2-ethyl-1-hexanol, and combinations thereof, and wherein at least one of R1 or R2 but not both is H.
A compound having the structure:
- wherein R1 and R2 are independently selected from the group comprising H, alkyl, alkenyl, cycloalkyl, chloroalkyl, chlorocycloalkyl, polyoxyethylene, polyoxypropylene, or a mixture thereof, and wherein at least one of R1 or R2 but not both is H.
