Abstract

PROCEDIMIENTO PARA PREPARAR ESTERES DE ALQUILO C8-C20 DE ACIDO 3,5-DI-TERC-BUTIL-4-HIDROXIBENZOICO.CONSISTE EN LA REACCION DEL ACIDO 3,5-DI-TERC-BUTIL-4-HIDROXIBENZOICO, CON UN ALCOHOL C8-C20, A TEMPERATURA ELEVADA, EN PRESENCIA DE UN CATALIZADOR DE RESINA INTERCAMBIADORA DE IONES FUERTEMENTE ACIDA. LA REACCION A 130-140JC, Y LA RESINA INTERCAMBIADORA DE IONES ES DE TIPO GEL Y COMPRENDE UN COPOLIMERO SULFONADO DE ESTIRENO Y DIVINILBENCENO. EL ALCOHOL C8-C20 SE ELIGE ENTRE 1-OCTANOL, 2-OCTANOL, 1-HEXADECANOL, 1-OCTADECANOL Y MEZCLAS DE LOS MISMOS. LA REACCION SE EFECTUA EN UN MEDIO DISOLVENTE SUSTANCIALMENTE INERTE, QUE TIENE UN PUNTO DE EBULLICION NORMAL DE 110 A 150J APROXIMADAMENTE.
