The article studies the possibilities of obtaining calcium hypochlorite and calcium chlorate with high added value by processing calcium chloride, a secondary product formed during the production of potassium sulfate at LLC "Sogda Kimyo Zavod". The conversion process used sodium hypochlorite solution produced at the caustic soda plant of JSC "Navoiyazot". Calcium chloride samples were analyzed using IR spectroscopy, XRD and XRF methods, and it was found that it has a high level of purity. In addition, the effect of temperature and reaction duration on the conversion process was evaluated, and optimal technological conditions for the formation of calcium hypochlorite and calcium chlorate were determined.
