Abstract

EN LA OBTENCION CONTINUADA DE ACIDO ISOBUTIRICO POR SINTESIS DE KOCH PARTIENDO DE PROPILENO, MONOXIDO DE CARBONO Y AGUA O UN ALCOHOL EN ACIDO FLUORHIDRICO A PRESION, SE DISMINUYE LA PRESION DE LA MEZCLA REACTIVA TRAS LA REACCION, SEPARANDOSE LOS COMPONENTES GASEOSOS. LA FASE LIQUIDA RESTANTE SE LLEVA A LA ZONA MEDIA O ALTA DE UNA COLUMNA DE DESTILACION. LA TEMPERATURA DE LODO SE MANTIENE POR ENCIMA DEL PUNTO DE EBULLICION DEL ACIDO ISOBUTIRICO Y LA TEMPERATURA DE LA CABEZA CERCANA AL PUNTO DE EBULLICION DEL ACIDO FLUORHIDRICO. SE OBTIENE ACIDO ISOBUTIRICO LIQUIDO DE UN ALTO GRADO DE PUREZA EN UN FONDO POR DEBAJO DEL LUGAR DE ENTRADA.
