Abstract

PROCEDIMIENTO PARA LA SEPARACION DE ACIDO ISOCIANICO A PARTIR DE UNA MEZCLA GASEOSA DE ACIDO ISOCIANICO Y AMONIACO POR ADICION DE UNA AMINA TERCIARIA O DE UN ETER A 250 S) C. LA MEZCLA REACTIVA GASEOSA SE HACE LLEGAR A UN DILUYENTE INERTE Y SE ENFRIA, CONDENSANDOSE UN ADUCTO DE ACIDO ISOCIANICO Y AMINA TERCIARIA O ETER Y SEPARANDOSE EL AMONIACO EN FORMA DE GAS. POR REACCION POSTERIOR DEL ADUCTO SE OBTIENE UNA UREA SUSTITUIDA ASIMETRICAMENTE, UN CARBAMATO, UN TIOCARBAMATO O UN ISOCIANATO SUSTITUIDO.
