Abstract

PROCEDIMIENTO PARA LA PREPARACION DE ACETALES DEL METILGLIOXAL. SE PARTE DE ALCOHOLES QUE NO SON MISCIBLES CON AGUA O SOLO SON LIMITADAMENTE MISCIBLES CON ELLA, TALES COMO N-BUTANOL, ISOBUTANOL, 2-ETILHEXANOL-1 O N-OCTANOL, Y UNA SOLUCION ACUOSA DE METILGLIOXAL EN PRESENCIA DE UN CATALIZADOR ACIDO A TEMPERATURAS ENTRE 30 Y 100 GRADOS CENTIGRADOS, ELIMINANDOSE POR DESTILACION AZEOTROPICA EL AGUA INCORPORADA CON LA SOLUCION DE METILGLIOXAL Y LA RESULTANTE DURANTE LA REACCION. COMO FORMADOR AZEOTROPICO SE UTILIZA UN EXCESO DE ALCOHOL A REACCIONAR, Y LA DESTILACION DEL AZEOTROPICO SE REALIZA A UNA DEPRESION ENTRE 0,01 Y 0,8 BARES.
