Abstract

LOS CARBONATOS DIALQUIL PUEDEN SER ELABORADOS MEDIANTE TRANSFORMACION DE MONOXIDO DE CARBONO CON NITRITOS ALQUIL EN REACCION DE FASE GASEOSA CONTINUA EN PRESENCIA DE UN CATALIZADOR, CON LO CUAL UN REACTOR DE LECHO SOLIDO SE UTILIZA CON LECHO DE CATALIZADOR CORTO EN LA DIRECCION DE CORRIENTE. CON ELLO SE FORMAN LOS CARBONATOS DIALQUIL EN SELECTIVIDAD CASI CUANTITATIVA, SIN QUE SE OBSERVE UNA DESCOMPOSICION TERMICA DEL NITRITO ALQUIL CON UNA FORMACION RESULTANTE CON ELLO DE PRODUCTOS DE DESCOMPOSICION.
