Abstract
LA ACETALIZACION SELECTIVA DE ALDEHIDOS POR REACCION DIRECTA CON ALCOHOLES Y ALQUILGLICOLES O POR TRANSCETALIZACION CON ALQUILORTOFORMIATOS (TOF) CATALIZADO POR ZEOLITAS Y ZEOTIPOS DE PORO MEDIO Y GRANDE CON ANILLOS DE 10 MIEMBROS O MAS CON CARACTERISTICAS ACIDAS. LOS ALDEHIDOS PUEDEN SER AROMATICOS, ALIFATICOS, LINEALES, RAMIFICADOS Y ALDEHIDOS QUE CONTENGAN ADEMAS FUNCION CETONA. EN ESTE CASO LOS CATALIZADORES ACETALIZAN LA FUNCION ALDEHIDO A UNA VELOCIDAD MUCHO MAYOR QUE LA CETONA, MOSTRANDO UNA ALTA CHEMOSELECTIVIDAD.
