Abstract

UN METODO PARA PRETRATAMIENTO DE UN CATALIZADOR DE PALADIO-ORO UTIL EN LA SINTESIS DE ACETATO DE VINILO. UN CATALIZADOR VIRGEN, QUE SIGUE LA REDUCCION AL PALADIO METALICO Y ORO, SE CALIENTE PRIMERO E TEMPERATURAS ELEVADAS EN PRESENCIA DE UN AGENTE OXIDANTE TAL COMO EL AIRE. EL AGENTE OXIDANTE ES RETIRADO Y SE INTRODUCE UN GAS INERTE TAL COMO EL NITROGENO. EL CATALIZADOR SE CALIENTE DE NUEVO A UNA TEMPERATURA DE HASTA 500 (GRADOS) C EN PRESENCIA DE UN AGENTE REDUCTOR TAL COMO HIDROGENO O ETILENO. SE OBTIENEN MEJORAS EN LA SELECTIVIDAD Y LA PRODUCCION.
