METHODS FOR THE PREPARATION OF BOROTRIHYDROXYGLUTARATE

A method of producing sodium borotrihydroxyglutarate in the form of non-toxic crystals comprising reacting in an aqueous medium trihydroxyglutaric acid and sodium borate of the general formula nNa2O.mB2O3.xH2O, wherein n = 1 to 2, m = 1 to 5, and x = 0 to 10. The sodium borate is prepared directly i...

Beschreibung
Zusammenfassung:	A method of producing sodium borotrihydroxyglutarate in the form of non-toxic crystals comprising reacting in an aqueous medium trihydroxyglutaric acid and sodium borate of the general formula nNa2O.mB2O3.xH2O, wherein n = 1 to 2, m = 1 to 5, and x = 0 to 10. The sodium borate is prepared directly in the reaction mixture by causing boric acid and sodium hydroxide to interact. The trihydroxyglutaric acid, boric acid and sodium hydroxide are taken in a molar ratio of about 1.1 : 1:2. In lieu of trihydroxyglutaric acid, zylotrihydroxyglutaric acid can bae utilized.
