Abstract
Inventia se refera la un procddeu de preparare a izoascorbatului de sodiu, prin reactia esterului metilic al acidului 2-cetogluconic cu solutie apoasa de bicarbonat, în care la o solutie metanolica a esterului metilic al acidului 2-cetogluconic se adauga la reflux într-o singura portie solutia apoasa 9% fierbinte de bicarbonat de sodiu, urmata de refluxarea la 80 degree C a amestecului timp de 45 min.The invention relates to a process for the preparation of sodium isoascorbate by the reaction of 2-ketogluconic acid methyl ester with aqueous bicarbonate solution, wherein to a methanolic solution of 2-ketogluconic acid methyl ester is added at reflux in a single portion of the aqueous 9% aqueous solution of sodium bicarbonate, followed by refluxing the mixture at 80 ° C for 45 minutes.
