Description

Известный способ обработки сульфокатионов заключаетс в том, что супьфокатиониты обрабатывают аммиачной водой или аминами при температуре около 2ОО С в течение нескольких часов, В результате та кой обработки .получают анионообменники.A known method of processing sulfonic cations is that supofocationites are treated with ammonia water or amines at a temperature of about 2OO C for several hours. As a result of this processing, anion exchangers are obtained.
Предлагаетс обрабатывать, сульфокатионить раствором сульфита натри при ЮО14О С, При этом неактивна сера, не участ вуюша в обмене в нейтральных или кислых средах, переходит в активную, и обмекнай емкость катионитбв повышаетс . Повышение обменной емкости дл смолы КС составл ет 65-9О%, КУ-1 , КУ-2 10-20%. It is proposed to process the sulfonic cation with a solution of sodium sulfite at SO14O C. In this case, the inactive sulfur, not participating in the exchange in neutral or acidic media, becomes active, and the cation capacity of the cationites increases. The increase in exchange capacity for resin KS is 65-9%, KU-1, KU-2 10-20%.
Указанную обработку сульфокатионитов можно примен ть и дл смол, обменна емкость которых понижаетс в результате перехода активной серы в неактивную при термической обработке в процессе их эксплуатации .This treatment of sulfo cation exchangers can also be applied to resins whose exchange capacity decreases as a result of the conversion of active sulfur to inactive during heat treatment during their operation.
П р им ер. Сульфокатиониты, полученные как обычно, обрабатывают в автоклаве с рабочим давлением до 3 атм раствором сульфита натри концентрацией 1-5% и выше при 1ОО-140 С в течение14-12 ч„ После обработки сульфитом сульфокатионит дренируют и промывают от сульфита. Отработанный сульфитный раствор можно доукрепл ть сульфитомнатри по нуишой кон- центра ии и многократно использовать вновь. Расход сульфита составл ет около 40 кг на I т катионита.Pr im. Sulfo cation exchangers, obtained as usual, are treated in an autoclave with a working pressure of up to 3 atm with 1–5% sodium sulfite solution and more at 1OO-140 C for 14–12 h. After sulphite treatment, sulfo cation exchanger is drained and washed from sulphite. The spent sulphite solution can be strengthened with sulphite solu- tions according to their concentration and can be reused several times. Sulfite consumption is about 40 kg per t of cation exchanger.
