Abstract

SE HACE REACCIONAR UN OXIDO DE ALQUILENO CON UN COMPUESTO ORGANICO QUE TENGA UN ATOMO DE HIDROGENO REACTIVO, EN UN REACTOR DE SERPENTIN, ALREDEDOR DEL CUAL SE HA DISPUESTO UN CIRCUITO DE GASES (5,7,4) Y UN CIRCUITO DE LIQUIDOS (2,3,4) COMUNICADOS ENTRE SI POR MEDIO DE UNA VALVULA CON BOQUILLA MEZCLADORA DE ASPIRACION (4). PARA COMPLETAR LA REACCION E IMPEDIR LA FORMACION DE PRODUCTOS SECUNDARIOS, TALES COMO DIOXANO, ES IMPORTANTE DISMINUIR LA TEMPERATURA DE TODA LA FASE GASEOSA DE OXIDO DE ALQUILENO A UNA TEMPERATURA SITUADA POR DEBAJO DE LA TEMPERATURA DE LA FASE LIQUIDA, LO QUE SE CONSIGUE POR ADICION Y EVAPORACION DE OXIDO DE ALQUILENO LIQUIDO Y REFRIGERACION DE LA FASE GASEOSA A TRAVES DE LAS PAREDES DE LA INSTALACION (13).
