Abstract

LOS ALCOHOLATOS DE ALCOHOLES SUPERIORES Y/O POLIVALENTES SE OBTIENEN GENERALMENTE POR TRANSFORMACION DE ALCOHOLES INFERIORES CON LOS CORRESPONDIENTES ALCOHOLES SUPERIORES, DEBIENDOSE DE SEPARAR DE LA MEZCLA DEL PRODUCTO LOS ALCOHOLES INFERIORES QUE HAN APARECIDO CON UN ELEVADO GASTO TERMICO PARA ASI AISLAR EL ALCOHOLATO SUPERIOR. DE ACUERDO CON LA INVENCION SE REALIZA LA TRANSALCOHOLIZACION EN FASE LIQUIDA BAJO LAINFLUENCIA DE UN CAMPO ELECTRICO DE FORMA ELECTROLITICA O ELECTRODIALITICA. DISMINUYE EL GASTO PARA LA SEPARACION DE LOS ALCOHOLES INFERIORES. OBTENCION DE ALCOHOLATOS ESPECIALES.
