Abstract

Procedimiento para la obtención de ésteres del ácido glioxílico, caracterizado porque se hace reaccionar un hemiacetal del éster del ácido glioxílico a) directamente con un alcohol en presencia de un catalizador o b) en primer lugar se transforma en el acetal completo del éster del ácido glioxílico correspondiente y, a continuación, se transesterifica con un alcohol en presencia de un catalizador, llevándose a cabo, después de a) y b), una disociación del acetal para dar el éster libre del ácido glioxílico o su hidrato deseado.
