Abstract

Empezando a partir de una mezcla que contiene tocoferoles, grasas y/o derivados de grasa, más particularmente ácidos grasos, y opcionalmente esterol y/o derivados de esterol, los ácidos grasos libres presentes en la mezcla se esterifican con un alcohol en presencia de un catalizador oxido de zinc y/o hidroxido de zinc. Después de las esterificaciones, el exceso de alcohol ionferior es removido por destilzacion de la mezcla de la reaccion. El catalizador de transesterificacion y el glicerol presentes, eventualmente, son removidos y el éster de alquilo de ácido graso es removido por destilacion de la mezcla. La destilacion de ésteres de alquilo de ácido graso puede lograrse con una columna empaquetada en secuencia con un evaporador de película frotada. Se puede recuperar simultáneamente tocoferol y esterol. Los tocoferoles y esteroles pueden separarse mediante la cristalizacion de los esteroles a partir de una mezcla de solventes orgánicos.
