Abstract

L'invention concerne l'obtention de peroxydicarbonates. Le procédé consiste à utiliser un mélange aqueux contenant du chloroformiate et au moins un excès stoechiométrique de 4 % de peroxyde d'hydrogène par rapport à la quantité de chloroformiate, ledit mélange ayant une teneur en peroxyde d'hydrogène entre environ 10 % et environ 35 % en poids par rapport à la quantité d'eau, et à faire réagir ledit mélange avec un excès stoechiométrique d'au moins 1 % d'hydroxyde de métal alcalin par rapport à la quantité de chloroformiate, ledit hydroxyde de métal alcalin se présentant sous la forme d'une solution aqueuse contenant entre environ 20 % et environ 40 % en poids d'un hydroxyde de métal alcalin, et à récupérer le peroxydicarbonate à partir du mélange réactionnel. Selon une variante, on ajoute simultanément et par fractions au chloroformiate une solution aqueuse de peroxyde d'hydrogène et une solution aqueuse d'hydroxyde de métal alcalin. Application : obtention de peroxydicarbonates.The invention relates to the production of peroxydicarbonates. The process involves using an aqueous mixture containing chloroformate and at least a 4% stoichiometric excess of hydrogen peroxide relative to the amount of chloroformate, said mixture having a hydrogen peroxide content between about 10% and about 35. % by weight relative to the amount of water, and reacting said mixture with a stoichiometric excess of at least 1% of alkali metal hydroxide relative to the amount of chloroformate, said alkali metal hydroxide being present under form an aqueous solution containing between about 20% and about 40% by weight of an alkali metal hydroxide, and recovering the peroxydicarbonate from the reaction mixture. According to one variant, an aqueous solution of hydrogen peroxide and an aqueous solution of alkali metal hydroxide are added simultaneously and in portions to the chloroformate. Application: obtaining peroxydicarbonates.
