Description
рола. Через 0,5 час образуетс смола в виде сферических гранул, постепенно повыша температуру до 70°С, их выдерживают 0,5 час. Гранулы обрабатывают сразу гор чей дистиллированной водой (80-90°С), сушат на воздухе 24 час, затем 5 час ири темиературе 100- 110°С. Далее гранулы сульфируют в трехгорлой колбе концеитрироваипой сериой кислотой (d 1,83 г/см) в течение 5 час ири температуре 90°С.rola. After 0.5 hour, a resin in the form of spherical granules is formed, gradually raising the temperature to 70 ° C, they are kept for 0.5 hour. The granules are treated immediately with hot distilled water (80-90 ° C), dried in air for 24 hours, then for 5 hours at a temperature of 100-110 ° C. Next, the granules are sulphurized in a three-necked flask with a final nitrile seric acid (d 1.83 g / cm) for 5 hours at a temperature of 90 ° C.
Получениый в виде гранул катион гг и)омывают до нейтральной реакции и перевод т в Н-форму согласно ГОСТУ 10895-64.The cation gg and) obtained in the form of granules is washed until neutral and converted to the H-form according to GOST 10895-64.
Основные иоказатели катионита следующие:The main indications of cation exchanger are as follows:

Катионит, иолучаемый согласно известному способу, имеет статистическую обменную емкость по 0,1 н. раствору NaOH 4 мг-экв/г, после обработки 0,5 н. H2SO4-3,8 мг-экв/г. Технико-экономическа эффективность способа, согласно изобретению, обусловлеиа сокрашением времени проведени процесса и полным исключеиием расхода органического растворител дл промывки получепного иоликоиденсаиионного продукта.The cation exchanger, which is obtained according to a known method, has a statistical exchange capacity of 0.1 n. a solution of NaOH 4 mEq / g, after treatment with 0.5 n. H2SO4-3.8 mg-eq / g. Technical and economic efficiency of the method according to the invention, due to the shortening of the time of the process and the complete elimination of the consumption of organic solvent for washing the obtained iolic condensate and ionic product.
