A compound of structural Formula F-I:
- wherein R1 and R2 are independently each a hydrocarbyl group comprising at least two carbon atoms;
- and R3 is a glycol ether or a polyglycol ether.
A method for making an ester product comprising an ester compound of the structural Formula F-I:
- wherein R1 and R2 are each independently a hydrocarbyl group comprising at least two carbon atoms, and R3 is a glycol ether or polyglycol ether;
- the method comprising the steps of:
