Abstract
A method for esterifying an unsweated, oil containing wax oxidate includes the use of an alcohol such as methanol and an organic sulfonic acid such as methane sulfonic acid. The use of methane sulfonic acid results in the clean separation of the ester from water which is used to wash the acid catalyst from the ester after esterification. Previously, the use of a strong mineral acid such as sulfuric acid resulted in an emulsion forming after the esterification of an unsweated oil containing wax oxidate.
