Abstract

Cette invention se rapporte à la classe des produits chimiques qui contiennent de l'oxygène actif et qui peuvent être utilisés en tant que tel ou entrer dans la composition d'agent de nettoyage et de lavage, d'agents de blanchiment, ainsi que de préparations de parfumerie ou antiseptiques. Cette invention concerne essentiellement un procédé de production de perborate de calcium dont la composition est CaO*B2O3*nH2O (où n = 3,1 - 3,6) et qui contient de 20 à 23 % d'oxygène actif. Cette invention se caractérise en ce qu'on utilise, dans la synthèse du produit fini, un diborate de calcium qui est humide ou séché à une température ne dépassant pas 60° C, et qui correspond à la formule CaO*B2O3*nH2O (où n = 6 - 7).
