Description
Известен способ получени ионообменных смол из полиэтиленполиамидного основани обработкой последнего формальдегидом и алифатическими соединени ми, содержащими карбонильную группу.A method of producing ion exchange resins from polyethylene polyamide base is known by treating the latter with formaldehyde and aliphatic compounds containing a carbonyl group.
Предлагаемый способ получени апионообменных смол заключаетс в том, что метилолпроизводные фенола и алкиленполиамина, полученные обработкой последних формалином, подвергают соконденсащш при температуре 75-85°, в присутствии минеральной 35-40%-ной кислоты , с последующей сущкой образовавшегос гел при 60-90°, его прогреванием при 150-200° в течение 8-15 час- и измельчением.The proposed method for the preparation of apion exchange resins is that methylol derivatives of phenol and alkylene polyamine, obtained by treating the latter with formalin, are subjected to co-condensation at a temperature of 75-85 °, in the presence of mineral 35-40% acid, followed by an essence of gel formed at 60-90 ° heating it at 150-200 ° for 8-15 hours and grinding.
Дл получени указанных анионитов в зернистом состо нии реакционную массу в стадии конденсации эмульгируют в веретенном масле, вз том в соотношении 2 : 1, в течение двух часов при 75-80°, затем гранулы отдел ют от масла и прокаливают в течение 10 час. при температуре 150-170°.In order to obtain these anion exchangers in a granular state, the reaction mass in the condensation stage is emulsified in spun oil, taken in a 2: 1 ratio, for two hours at 75-80 °, then the granules are separated from the oil and calcined for 10 hours. at a temperature of 150-170 °.
Пример 1. 46,5 г (0,5 мол ) фенола нагревают 2 часа при 95- 100 с 225 мл 40%-ного раствора формалина (1,5 мол ) и получают метилольное производное фенола.Example 1. 46.5 g (0.5 mol) of phenol are heated for 2 hours at 95-100 with 225 ml of 40% formalin solution (1.5 mol) and a methylol derivative of phenol is obtained.
57,5 г (0,25 мол ) полиэтиленполиамина смешивают с 35 мл воды и приливают тонкой струей при перемешивании к 225 мл 40%-ного раствора формалина (1,5 мол ), после чего смесь нагревают в течение часа при температуре 85-90° и получают метилолпроизводное полиэтиленполиамина .57.5 g (0.25 mol) of polyethylene polyamine is mixed with 35 ml of water and poured with a thin stream with stirring to 225 ml of 40% formalin solution (1.5 mol), after which the mixture is heated for one hour at a temperature of 85-90 ° and get methylol-derived polyethylene polyamine.
К гор чему раствору метилолпроизводного полиэтиленполиамина приливают при перемешивании раствор метилолпроизводного фенола и через 3 мин. 180 мл концентрированной сол ной кислоты, затем в течение 15 мин. еще постепенно приливают 70 мл такой же кислоты, и, не прекраща перемешивани , поднимают температуру до 85-88°.A solution of methylol phenol and, after 3 minutes, are poured into the hot solution of the methylol derivative of polyethylene polyamine with stirring. 180 ml of concentrated hydrochloric acid, then for 15 minutes. 70 ml of the same acid are gradually added, and, without stopping the stirring, the temperature is raised to 85-88 °.
В этих услови х массу выдерживают до начала загустени (30- 40 мин.).Under these conditions, the mass is kept until the beginning of thickening (30-40 min.).
