Description
Пред Метом изобретени вл етс способ получени катионпта на основе полистирола, с при1 1енением органического растворител и реакции сульфированп .The pre Metom of the invention is a method for producing a polystyrene based cation, with the addition of an organic solvent and a sulfonated reaction.
Предлагаемый способ по сравкеито с известным более прост и позвол ет получить более дешевый продукт .The proposed method, compared to the known one, is simpler and allows a cheaper product to be obtained.
Особеююсть способа состоит в том, что полистирол раствор ют, ьппример, в дихлорэтане и пол чен :ый раствор нагревают в пр сутCTBJUi хлористого алюмини в качестве катализатора, после чего процесс провод т известными j p: eмами .A special feature of the process is that polystyrene is dissolved, for example, in dichloroethane and the solution is obtained: the solution is heated in a right way CTBJUi aluminum chloride as a catalyst, after which the process is carried out with known jp: emami.
Способ осуществл ют следующим образом.The method is carried out as follows.
В реактор загружают 10 вес. ч. полистирола в виде порошка, стружки или кусочков размером до 5 мм и 80 вес. ч. дихлорэтана. Смесь при подогревании размешивают и после получени однородного раствора добавл ют к нему 1 вес. ч. безводного хлористого алюмини .In the reactor load 10 wt. including polystyrene in the form of powder, chips or pieces up to 5 mm in size and 80 wt. dichloroethane. When the mixture is heated, the mixture is stirred and after obtaining a homogeneous solution, 1 weight is added to it. including anhydrous aluminum chloride.
РеакционнлЮ смесь при слабомReaction mixture with a weak
кипении выдерживают два-три часа , после чего отгон ют свободный дихлорэтан, а в набухший гель при:1:шают равный объем 25%-ной тех ;ической серной кислоты.The boiling is kept for two to three hours, after which free dichloroethane is distilled off, and in the swollen gel at: 1: an equal volume of 25% of those is added, with sulfuric acid.
Реакцию сульфировани ведут при 100° 3 тсчоше 5-6 часов.The sulfonation reaction is carried out at 100 ° 3 with a quench of 5-6 hours.
Затем ;: быток кислоты сливают, и полученный сульфоиолимер сушат н изме.:ь-;йют. Выход товарного продукта составл ет 140% от веса полистирола .Then;: the acid overflow is drained, and the resulting sulfoiolimer is dried on meas.: B-; The yield of the marketable product is 140% by weight of polystyrene.
Пред I.: е т ;: з о б р е т е н и Pre I: et:: about the t
Способ получени катионита I.a основе полистирола, с примене11ием органического растворител и реакции сульфировани , о т л и ч а ющ и и с тем, что, с целью упрош ,ени процесса и удешевлени каТ1юнита , полистирол раствор ют, например, з дихлорэтане и полученный раствор нагревают в присутствии хлористого алюмини , после чего ироцесс провод т известными лоиемазп;.The method of obtaining cation exchanger Ia based on polystyrene, with the use of an organic solvent and the reaction of sulphurization, is made with the fact that, in order to simplify the process and reduce the cost of plinth, polystyrene is dissolved, for example, with dichloroethane and the resulting solution heated in the presence of aluminum chloride, after which the process is carried out by the known loyam;
