Title
(EN) PROCESS FOR PRODUCING 1,2-ETHANEDIOL DERIVATIVES
(FR) PROCEDE DE PRODUCTION DE DERIVES DE 1,2-ETHANEDIOL
Abstract
(EN)
A process for producing 1,2-ethanediol derivatives in high yields, which comprises esterifying an $g(a)-hydroxy acid derivative to synthesize an $g(a)-hydroxy acid ester derivative and reducing the obtained ester derivative in the same reactor in the presence of a sodium borohydride compound in a protic solvent or an aqueous aprotic polar solvent.
(FR)
Procédé de production de dérivés de 1,2-éthanédiol en grandes quantités, qui consiste à estérifier un dérivé d'acide $g(a)-hydroxylique pour synthétiser un dérivé ester d'$g(a)-hydroxyacide et à réduire le dérivé ester ainsi obtenu dans le même réacteur, en présence d'un composé de borohydrure de sodium dans un solvant protique ou un solvant polaire aprotique et aqueux.
