Abstract

L'INVENTION CONCERNE UN PROCEDE DE FABRICATION DE L'ACIDE PARAHYDROXYMANDELIQUE RACEMIQUE. SUIVANT CE PROCEDE ON CONDENSE DANS L'EAU EN PRESENCE D'UN AGENT ALCALIN, A UNE TEMPERATURE COMPRISE ENTRE 30 ET 100C, L'ACIDE GLYOXYLIQUE SUR UN EXCES DE PHENOL. APPLICATION A LA FABRICATION DE L'ACIDE PARAHYDROXYMANDELIQUE RACEMIQUE.THE INVENTION RELATES TO A PROCESS FOR MANUFACTURING RACEMIC PARAHYDROXYMANDELIC ACID. FOLLOWING THIS PROCESS, THE GLYOXYLIC ACID IS CONDENTED IN WATER IN THE PRESENCE OF AN ALKALINE AGENT, AT A TEMPERATURE BETWEEN 30 AND 100C, GLYOXYLIC ACID OVER AN EXCESS OF PHENOL. APPLICATION TO THE MANUFACTURE OF RACEMIC PARAHYDROXYMANDELIC ACID.
