Title (EN) PROCESS FOR THE PREPARATION OF A LIME PRODUCT CONTAINING ACTIVE OXYGEN
(FR) PROCEDE DE PREPARATION D'UN PRODUIT A BASE DE CHAUX
Abstract: front page image
(EN)The invention relates to a method for preparing a lime product containing active oxygen, in which caustic lime is reacted with an aqueous solution of hydrogen peroxide so as to produce a solid lime product containing active oxygen and comprising calcium peroxide and slaked lime, the aqueous solution of hydrogen peroxide containing a water-soluble salt of a non-transition metal, such as magnesium sulfate, and a water-soluble silicate.
(FR)L'invention concerne un procédé de préparation d'un produit à base de chaux contenant de l'oxygène actif, dans lequel de la chaux vive est mise à réagir avec une solution aqueuse de peroxyde d'hydrogène de façon à produire un produit solide contenant de l'oxygène actif et comprenant du peroxyde de calcium et de la chaux éteinte, la solution aqueuse de peroxyde d'hydrogène contenant un sel hydrosoluble d'un métal non transitionnel, notamment du sulfate de magnésium, et un silicate hydrosoluble.
