Abstract
Inventia se refera la un procedeu de purificare a sarii de sodiu a acidului =-(2,6-dicloranilina)-fenilacetic brute, constând în aceea ca în scopul distrugerii impuritatilor colorate,produsul brut se trateaza cu apa oxigenata 30% si apoi efectueaza doua rexristalizari din apa distilata.The invention relates to a process for the purification of sodium salt of crude β- (2,6-dichloroaniline) -phenylacetic acid, in that in order to destroy colored impurities, the crude product is treated with 30% hydrogen peroxide and then carried out two re-crystallizations from distilled water.
