Abstract

EL OBJETO DE LA INVENCION ES UN PROCEDIMIENTO PARA LA MEZCLA RAPIDA DE EDUCTOS PARA LA FOSGENIZACION DE AMINAS PARA DAR LOS CORRESPONDIENTES ISOCIANATOS EN FASE GASEOSA. PARA UNA MEZCLA RAPIDA SE UTILIZAN MEZCLADORES DE MICROESTRUCTURA. LOS EDUCTOS SALEN EN FORMA DE GOTAS FINAS DEL COMPONENTE, Y SE MEZCLAN ENTONCES MUY RAPIDO MEDIANTE DIFUSION Y/O TURBULENCIA. DE ESTA MANERA EL PROCESO DE MEZCLA SE ACELERA EN COMPARACION CON LOS REACTORES CONVENCIONALES Y SE MEJORA EL RENDIMIENTO.
