Abstract

Se aisla trimetilolpropano a partir de una mezcla de reaccion, obtenida mediante la reaccion de n-butiraldehido con formaldehido en presencia de una base e hidrogenacion opcional de la mezcla obtenida. La mezcla es destilada utilizando una columna de separacion o una columna de destilacion con una columna anterior o una columna de destilacion posterior. El metodo esta caracterizado por una baja inversion y costo de energia y la formacion reducida de subproductos de alto punto de ebullicion.
