Показано, что введение органических веществ оказывает ингибирующее действие на образование кристаллов сульфата калия. Наибольшее ингибирующее действие оказывают модификаторы, содержащие сульфоновые, сульфатные и фосфоновые функциональные группы. Эффективность модификаторов, содержащих карбоксильные группы, существенно ниже. Образование стабильных пересыщенных растворов сульфата калия достигается при введении органических модификаторов в количестве 0,25‒0,50 %.</p></abstract><trans-abstract xml:lang="en"><p>The process of potassium sulfate crystallization from aqueous solutions in the presence of organic modifiers containing phosphonic, phosphate, sulfonic, sulfate and carboxyl functional groups has been studied. It is shown that the introduction of organic substances has an inhibitory effect on the formation of potassium sulfate crystals. Modifiers containing sulfonic, sulfate and phosphonic functional groups have the greatest inhibitory effect. The effectiveness of modifiers containing carboxyl groups is significantly lower. The formation of stable supersaturated solutions of potassium sulfate is achieved by introducing organic modifiers in an amount of 0.25 – 0.50%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кристаллизация</kwd><kwd>сульфат калия</kwd><kwd>модификаторы</kwd><kwd>зародыши</kwd><kwd>критический радиус</kwd><kwd>пересыщение</kwd><kwd>скорость образования зародышей</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Crystallization</kwd><kwd>potassium sulfate</kwd><kwd>modifiers</kwd><kwd>nuclei</kwd><kwd>critical radius</kwd><kwd>supersaturation</kwd><kwd>nucleation rate</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mubarak, Y.
