Изобретение относится к получению сульфокатионитов и касается стадии гидратации катионообменных смол после стадии сульфирования с целью удаления серной кислоты из суспензий, содержащих серную кислоту и сульфированные катиониты. Изобретение обеспечивает ускорение процесса гидратации и снижение отходов. Это достигается тем, что через стационарный слой сульфированного сополимера стирола с дивинилбензолом пропускают растворы серной кислоты со снижающейся концентрацией: в начале пропускают серную кислоту с концентрацией 45-60 %, а затем растворами,у которых концентрация каждого последующего на 12-18 % ниже по отношению к предыдущему раствору.The invention relates to the production of sulfonic cation exchangers and relates to the stage of hydration of cation-exchange resins after the sulfonation stage in order to remove sulfuric acid from suspensions containing sulfuric acid and sulfonated cation exchangers. The invention provides for the acceleration of the hydration process and the reduction of waste. This is achieved by passing through a stationary layer of sulfonated copolymer of styrene with divinylbenzene, solutions of sulfuric acid with a decreasing concentration are passed: at the beginning, sulfuric acid with a concentration of 45-60% is passed, and then solutions, in which the concentration of each subsequent is 12-18% lower relative to to the previous solution.
