Abstract

UN PROCESO PARA PREPARAR UN CATALIZADOR DE SILICE-TITANIA AÑADIENDO UNA SOLUCION ACIDICA CONTENIENDO UN COMPUESTO DE SILICIO TAL COMO SILICATO SODICO Y UN COMPUESTO DE TITANIO TAL COMO SULFATO DE TITANIO, DISUELTOS EN EL, A UNA SOLUCION DE UN COMPUESTO TAL COMO BICARBONATO DE AMONIO PARA OBTENER CO-PRECIPITACION, Y DONDE LA SOLUCION ACIDICA ES UNA SOLUCION ACIDICA DE ACIDO NITRICO ALTAMENTE CONCENTRADO O ACIDICA DE ACIDO SULFURICO, Y UNA PROPORCION DEL COMPUESTO DE TITANIO DISUELTO EN LA SOLUCION ACIDICA SE REGULA DE ALGUN MODO. DE CONFORMIDAD CON ESTE PROCESO, PUEDE OBTENERSE EFICAZMENTE UN CATALIZADOR CAPAZ DE EJERCER UN GRAN RENDIMIENTO EN UNA REACCION DE ESTERIFICACION Y SIMILARES.
