Claims (1)

Способ относится к технологии получения гидроокиси щелочного металла хлорощелочным электролизом, в котором раствор хлорида щелочного металла подвергают электролизу для получения гидроокиси щелочного металла, хлора и водорода и в котором по меньшей мере часть используемого для электролиза хлорида щелочного металла получают нейтрализацией карбоната щелочного металла хлором или хлористым водородом.The method relates to the technology of producing alkali metal hydroxide by chlor-alkali electrolysis, in which the alkali metal chloride solution is subjected to electrolysis to obtain alkali metal hydroxide, chlorine and hydrogen, and in which at least part of the alkali metal chloride used for electrolysis is obtained by neutralizing the alkali metal carbonate with chlorine or hydrogen chloride .
