Abstract

AQUI SE DESCUBREN PROCESOS MEJORADOS PARA LA PREPARACION DE ETER CARBOXILATOS POR REACCION EN UN MEDIO DE REACCION ALCALINA DE SALES DE ACIDO MALEICO Y UN ACIDO CARBOXILICO O POLICARBOXILICO, TENIENDO UN GRUPO HIDROXILO REACTIVO SOBRE UN ATOMO DE CARBONO NO CARBONILO EN PRESENCIA DE UN CATALIZADOR DE ION CALCICO EN DONDE SALES ACIDAS NO REACCIONADAS SE SE RECUPERAN DEL MEDIO DE REACCION REBAJANDO EL PH DEL MEDIO DE REACCION A UN RANGO DE DESDE ALREDEDOR DE 4 A ALREDEDOR DE 6. LAS SALES PRECIPITADAS SE RECICLAN A LA REACCION DE SINTESIS PARA PREPARAR CANTIDADES ADICIONALES DE PRODUCTO.
