PROCEDIMIENTO PARA LA PREPARACION DE DIESTERES DE ACIDO MALONICO EN UN REACTOR CON INTERCAMBIADORES INTERNOS DE CALOR.

摘要

A process for preparing malonic diesters by carbonylation of haloacetic esters and reaction with monohydric alcohols and a base in the presence of a transition metal catalyst, preferably a catalytic cobalt carbonyl complex, using a stirred reactor with one or more internal heat exchangers. The stirred reactor preferably contains a sparging stirrer.
