Abstract: Epoxidized fatty acid alkyl esters and methods for making epoxidized fatty acid alkyl esters. Such epoxidized fatty acid alkyl esters can be prepared by epoxidizing fatty acid alkyl esters with an acid and a peroxide. Epoxidation can be performed under controlled reaction conditions to provide epoxidized fatty acid alkyl esters having an iodine value in the range of from 4 to 15 g I2 / 100 g of epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizer compositions, either alone or in combination with other plasticizers, such as epoxidized natural oils. Such plasticizers in turn may be used in the formation of polymeric compositions.

Abstract: Métodos para fabricar ésteres de alquilo de ácidos grasos epoxidados. Tales ésteres de alquilo de ácidos grasos epoxidados pueden prepararse por epoxidación de un aceite natural con un ácido y un peróxido. El ácido residual en el aceite natural epoxidado no se neutraliza, tal como con una base, antes de la esterificación para producir los ésteres de alquilo de ácidos grasos epoxidados. Los ésteres de alquilo de ácidos grasos epoxidados se pueden emplear en plastificantes, ya sea solo o en combinación con otros plastificantes, tales como aceites naturales epoxidados. Tales plastificantes a su vez pueden ser utilizados en la formación de composiciones poliméricas.
