Abstract
A method of forming a substituted or unsubstituted gamma-lactone includes forming a reaction mixture that includes a substituted or unsubstituted cyano(C4-C10)alkene and / or a hydrolysis reaction product thereof. The reaction mixture also includes an acid, a solid acid catalyst, or a combination thereof. The method includes allowing the reaction mixture to react to form the substituted or unsubstituted gamma-lactone.
