Annotation

The article discusses the dependence of the product yield on temperature and current density in the process carried out in an electrolyzer with horizontally installed electrodes in a closed flow mode. In order to prevent side processes, oxide-ruthenium titanium anodes (ORTA) are used in the installation. The article also provides factors affecting the formation of potassium hydroxide. For the experiments, potassium chloride solutions prepared from purified potash fertilizer produced at JSC "Dekhkanabad Potash Plant" natural source materials were used.

Keywords

potassium hydroxide
mineral fertilizer
electrolysis unit
potassium chloride
ruthenium oxide titanium anodes
free active chlorine.
ion exchange membrane
