Изобретение относитс к технологии получени растворов гипохлоритов, используемых в частности в качестве дезинфицирующих растворов .This invention relates to a process for the preparation of hypochlorite solutions used in particular as disinfecting solutions.
Известен способ получени растворов гипохлоритов , например гиоохлорита натри путем электролиза раствора хлорида натри . Дл предотвращени катодного восстановлени гйпохлорита в электролит ввод т добавки (хлористый кальций, бихромат натри и др.)НедостаткамИ известного способа вл ютс низкий выход продукта и загр знение получаемых дезинфицирующих растворов веществами , вводимыми в электролит (хлористым кальцием, бихроматом натри и др.).A known method for producing solutions of hypochlorites, for example sodium hypochlorite, is obtained by electrolysis of a solution of sodium chloride. To prevent cathodic reduction of hypochlorite, additives are added to the electrolyte (calcium chloride, sodium bichromate, etc.). The disadvantages of this method are low product yield and contamination of the resulting disinfectant solutions with substances introduced into the electrolyte (calcium chloride, sodium bichromate, etc.).
Дл повышени выхода продукта предлагаетс процесс вести при соотнощении катодной плотности тока к анодной, равном 2-12,5:1. To increase the yield of the product, the process is proposed to be carried out at a ratio of cathode current to anodic density equal to 2-12.5: 1.
Дл повыщени катодной плотности тока To increase cathode current density
активную поверхность катода покрывают сеткой из токонеправод щих материалов.The active surface of the cathode is covered with a grid of current-conducting materials.
При электролизе 5%-ного раствора хлорнда натри при температуре 30°С, анодной плотности тока 18 а/дм и 30 а/дм-, соотношении катодной и анодной плотностей тока 2:1 за счет экранировани -катода нейтральной диафрагмой из хлориновой ткани, а также из асбестовой тканн, степень разложени хлорида натри с образованием гйпохлорита увеличиваетс на 10% (хлоринова ткань) и на 30% (асбестова диафрагма).In the electrolysis of 5% sodium chlorindium solution at 30 ° C, anodic current density of 18 a / dm and 30 a / dm, the ratio of cathodic and anodic current density of 2: 1 due to the screening of the cathode by a neutral diaphragm from chlorine tissue, and also from asbestos tissue, the degree of decomposition of sodium chloride to form hypochlorite is increased by 10% (chlorinated fabric) and by 30% (asbestos diaphragm).
Предмет изобретени Subject invention
Способ получени гипохлоритов путем электролиза растворов хлоридов, отличающийс тем, ЧТО, с целью повыщени выхода продукта , электролиз ведут при соотнощенни катодной плотности тока к анодной, равном 2-2,5:1.The method of obtaining hypochlorites by electrolysis of chloride solutions, characterized in that, in order to increase the yield of the product, the electrolysis is carried out at a ratio of the cathodic current density to the anodic current equal to 2-2.5: 1.
