PROCESSES FOR MAKING RENEWABLE SOURCE-BASED CITRATE ESTERS AND ACYLATED CITRATE ESTERS

Page/Page column 8, (2012/03/26)
Improved processes are described for making trialkyl esters and acylated trialkyl esters of carboxylic acids, as well as epoxidized trialkyl esters and acylated trialkyl carboxylate esters, such as are used in developing plasticized PVC compositions. In particular, processes are described for conducting the esterification and acylation steps involved in making the acylated trialkyl esters in a single vessel without an intermediate purification step, by means of a Lewis acid metal triflate catalyst.
