Abstract
Inventia se refera la un procedeu de obtinere a metaboratului de sodiu cristalizat cu 8 H2O prin tratarea boraxului decahidrat termic cu hidroxid de sodiu tehnic, constand în aceea ca în scopul obtinerii unui produs pur, utilizeaza un raport molar între reactanti de 0,44 si un raport între hidroxidul de sodiu si apa de solubilizare de 0,14 si cristalizare dintr-un volum egal de acetona.The invention relates to a process for obtaining sodium metaborate crystallized with 8 H2O by treating the thermal decahydrate borax with technical sodium hydroxide, that in order to obtain a pure product, use a molar ratio of reactants of 0.44 to one ratio between sodium hydroxide and solubilizing water of 0.14 and crystallization from an equal volume of acetone.
