A method of making a benzyl cis-cyclohexane 1,2-dicarboxylate triester having the steps: a. forming a reaction mixture by reacting the following three components: i. a synthetic or biobased reagent selected from the group consisting of an alpha-hydroxyester and a beta-hydroxyester, ii. an anhydride selected from the group consisting of cis-hexahydrophthalic anhydride, 4-methylcyclohexane-1,2-dicarboxylic anhydride, and 3-methylcyclohexane-1,2-dicarboxylic anhydride, and iii. an alkylamine catalyst; and b. contacting benzyl chloride with the reaction mixture to yield a product that is free of phthalates and includes at least one benzyl cis-cyclohexane 1,2-dicarboxylate triester.

Triesters from alpha-and-beta-hydroxyesters

A process of transesterifying biobased epoxidized vegetable oils with a dialkyl carbonate produces mixtures of epoxidized fatty acid cyclic glycerin carbonate esters and epoxidized fatty acid alkyl esters.

Plasticizer mixture of epoxidized fatty acid glycerin carbonate ester and epoxidized fatty acid esters

The present invention provides compounds having both a pendent ether group and a pendent ester group that are useful as plasticizers for polymer resin and methods of making and using the same. In one embodiment of the invention, compounds according to the invention are formed by converting at least one, but not all, of the hydroxyl groups of a polyol having three or more hydroxyl groups (e.g., gylcerol, pentaerythritol or dipentaerythritol) to a pendent ether group to form a partially-etherized intermediate, and then converting at least one of the remaining hydroxyl groups in the partially-etherized intermediate to a pendent ester group.
