Bodak P. 3.Physico-chemical regularities and technology of unchloride potassium fertilizer production on the base of high- chloride industrial shoenite and selective extractant- ethanolamine

3. The dissertation is devoted to investigations of physico- chemical regularities and design of unchloride potassium sulphate fertilizer technology by the treatment of chloride-contents shoenite with the use of selective organic extractant. Methods of investigations- chemical and physico-chemical ( flame photometry, pH-metry, electronic microscopy, X-ray) analyses. The processes of phase-obtaining of potassium and sodium chlorides in organic medium has been investigated. The optimal parameters of chloride extraction of high-chloride shoenite and new technology of unchloride potassium fertilizer has been determined. Economic effect from the implementation of the proposed technology as the result of conditional unchloride potassium fertilizers production was proved. Potassium Enterprises of Ukraine are the field of use.
