Abstract

ES UN PROCEDIMIENTO Y UN DISPOSITIVO PARA LA PREPARACION DE POLIISOCIANATOS QUE CONTIENEN COMO REACTIVOS GRUPOS BIURET (CICLO)ALIFATICOS A PARTIR DE DIISOCIANATOS (CICLO)ALIFATICOS Y VAPOR DE AGUA O UNA SUSTANCIA DESHIDRATANTE, SIENDO MEZCLADOS ENTRE SI EN UN REACTOR DE AGITACION, LOS REACTIVOS SON CONDUCIDOS EN CONTRACORRIENTE POR UN REACTOR DE AGITACION EN CASCADA QUE CONSTA DE AL MENOS DOS FASES. CON ELLO, SE INTENSIFICA LA DISTRIBUCION DEL REACTIVO GASEOSO EN EL REACTIVO LIQUIDO A TRAVES DE UNOS ELEMENTOS PERTURBADORES QUE HAY INSTALADOS EN EL REACTOR DE AGITACION. COMO ELEMENTOS PERTURBADORES SE UTILIZAN UNAS ARANDELAS PROVISTAS DE UNOS ORIFICIOS Y DISPUESTAS A DISTANCIA UNAS DE OTRAS Y/O LISTONES DE PERTURBACION QUE DISCURREN EN DIRECCION LONGITUDINAL DEL REACTOR DE AGITACION.
