Title (EN) CALCIUM PERBORATE AND METHOD FOR PRODUCING THE SAME
(FR) PERBORATE DE CALCIUM ET PROCEDE DE PRODUCTION
Abstract: front page image
(EN)The present invention relates to the class of chemicals that contain active oxygen and that can be used either alone or in the composition of cleaning or washing agents, bleaching agents or perfumery or antiseptic preparations. This invention essentially relates to a method for producing calcium perborate having the following composition CaO*B2O3*nH2O (where n = 3.1 - 3.6) and containing from 20 to 23 % of active oxygen. This invention is characterised in that it involves using for the synthesis of the finished product a calcium diborate which is humid or dried at a temperature not exceeding 60° C and corresponds to the formula CaO*B2O3*nH2O (where n = 6 - 7).
(FR)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).
