Abstract
LA PERACETILACION DE POLIALCOHOLES QUE TENGAN POR LO MENOS CUATRO ATOMOS DE CARBONO SE HACE MAS ECONOMICA EN CUANTO A DEMANDA DE CATALIZADOR Y CONSUMO DE ANHIDRIDO ACETICO ACETILANDO EN DOS ETAPAS. LA PRIMERA ETAPA COMPRENDE LA ACETILACION PARCIAL DEL POLIALCOHOL CON ACIDO ACETICO SIN USAR CATALIZADOR Y, POSTERIORMENTE SEPARANDO EL EXCESO DE ACIDO ACETICO Y EL AGUA DE REACCION, Y LA SEGUNDA ETAPA COMPRENDE LA PERACETILACION DEL PRODUCTO PARCIALMENTE ACETILADO CALENTANDOLO CON ANHIDRIDO ACETICO EN PRESENCIA DE CANTIDADES RELATIVAMENTE PEQUEÑAS DE ACETATO ALCALINO COMO CATALIZADOR.
