Abstract
SE PRESENTA UN PROCESO CONTINUO PARA LA HIDROCARBILTIACION DE AMINAS AROMATICAS. EL PROCESO CONSISTE EN FORMAR UNA MEZCLA DE UNA AMINA AROMATICA, UN DISULFURO DE HIDROCARBILO Y UNA CANTIDAD EFECTIVA DE UN CATALIZADOR DE ACIDO DE LEWIS Y PERMITIR DESPUES QUE TAL MEZCLA FLUYA A MODO DE PELICULA DELGADA A LO LARGO DE UNA COLUMNA. SE HACE PASAR A UN GAS INERTE, A MODO DE CONTRACORRIENTE, A TRAVES DE LA MEZCLA. A CONTINUACION SE SEPARA EL PRODUCTO DE AMINA AROMATICA DE TIOHIDROCARBILO LIQUIDO DEL EFLUENTE GASEOSO.
