Abstract
UN PROCEDIMIENTO PARA PURIFICACION DE UN ALCOHOL ISOPROPILICO BRUTO, TAL COMO UN PRODUCTO DE REACCIONES DE HIDRATACION DE PROPILENO, QUE CONTIENE ALCOHOL ISOPROPILICO, ETER DIISOPROPILICO, AGUA E IMPUREZAS POLIMERAS, DONDE EL ALCOHOL ISOPROPILICO BRUTO SE SOMETE A UNA SECUENCIA ESPECIFICA DE ETAPAS DE DILUCION MULTIPLE Y SEPARACION DE FASES, QUE SIRVE PARA EXTRAER UNA PARTE SUSTANCIAL DEL ETER DIISOPROPILICO Y LAS IMPUREZAS POLIMERAS. LA INVENCION ES ESPECIALMENTE UTIL PARA ELIMINAR LAS IMPUREZAS MALOLIENTES QUE CONTIENEN AZUFRE DE LOS PRODUCTOS DE PROCESOS DE HIDRATACION DIRECTA DE PROPILENO, QUE INCLUYEN LA REACCION DE PROPILENO CON ACIDO SULFURICO PARA FORMAR SULFATO DE ISOPROPILO SEGUIDA DE LA HIDROLISIS DEL SULFATO A ALCOHOL ISOPROPILICO.
