Abstract

Disclosed is a method for production of a methyl ester based formulation. The method involves: providing a feedstock containing about 1% to about 100% canola oil; removing water from the feedstock; heating the feedstock to at least about 60° C.; mixing a solution of about 90% to about 100% (v/v) methanol and a strong base with the heated feedstock to produce a mixture containing methyl ester; and allowing the mixture containing methyl ester to rest for at least one hour. The composition of the methanol and strong base solution being calculated based on the free fatty acid content of the feedstock. The methyl ester based formulations produced by the method can be used as ecofriendly penetrating oils, lubricating oils, machining fluid or releasing agents.

A method for production of a methyl ester based formulation, the method comprising the steps of:

(A) providing a feedstock comprising about 1% to about 100% canola oil, if the feedstock contains water, removing water from the feedstock;
(B) heating the feedstock to at least about 60° C.;
(C) adding a strong base and a solution of about 90% to about 100% (v/v) methanol to the heated feedstock to produce a mixture comprising methyl ester;
(D) allowing the mixture comprising methyl ester to settle for at least one hour, and separating a glycerine layer from the mixture comprising methyl ester;
and
(E) then adding about 1% (v/v) methanol or acetone and 1% to 40% (v/v) citric oil to the mixture comprising methyl ester to form the methyl ester based formulation.
