Description
Известен промышленный способ Получепи полипзобутилена с молекул рным весом 15000 и выше с применением в качестве инициатора процесса полимеризации раствора фтористого бора в этаноле и вводом последнего как хладоагента дл регулировани температуры полил:еризации .A known industrial method is Prichepi polyzobutylene with a molecular weight of 15,000 and higher, using as the initiator of the polymerization process a solution of boron fluoride in ethanol and introducing the latter as a refrigerant to control the temperature of the polyles: emerization.
Особенностью описываемого способа получени полиизобутилеиового масла вл етс то, что реакци полимеризации изобутилена протекает без ввода хладоагента, а температура процесса регулируетс испарением самого мономера. Инициирование процесса полимеризации осуществл етс спиртовыми комплексами фтористого бора. Этот способ позвол ет получать полиизобутиленовое масло с молекул рным весом 600-1200.A feature of the described method for producing polyisobutylene oil is that the isobutylene polymerization reaction proceeds without introducing a refrigerant, and the process temperature is controlled by the evaporation of the monomer itself. The initiation of the polymerization process is carried out with boron fluoride alcohol complexes. This method produces polyisobutylene oil with a molecular weight of 600-1200.
Пример. В сосуд Дьюара ввод т 500 мл (320 г) изобутилена. В полученную смесь постепенно, по капл м, добавл ют комплекс метанола с фтористым бором. Расход комплекса к изобутилену составл ет 0,3- 0,8Vo.Example. 500 ml (320 g) of isobutylene are introduced into the Dewar vessel. To the resulting mixture is gradually added dropwise a complex of methanol with boron fluoride. The consumption of the complex to isobutylene is 0.3-0.8Vo.
Через 40 сек. после начала реакции дл обрыва цепи и разложени спиртового комплекса фтористого бора в полимер ввод т «бупс в количестве IVo к полимеру.After 40 seconds After the start of the reaction, chain breaks and decomposition of the alcohol complex of boron fluoride are introduced into the polymer in the amount of IVo in the polymer.
Дл Здалени газообразных примесей из полимера полимерный продукт перенос т в колбу и нагревают в течение 1,5-2 час. при 120°. Далее иолимер перемешивают в течение 2 час. при температуре 100- 120° с зикеевской глиной, просушенной при 150°. Затем, полиизобутиленовое масло подогревают до 120-140° и фильтруют под вакуумом. После этого весь процесс контактировани полиизобутиленового масла с глиной и фильтрацией повтор ют.To create gaseous impurities from the polymer, the polymer product is transferred to a flask and heated for 1.5-2 hours. at 120 °. Next, the iolimer is stirred for 2 hours. at a temperature of 100-120 ° C with Zikei clay, dried at 150 ° C. Then, polyisobutylene oil is heated to 120-140 ° and filtered under vacuum. Thereafter, the entire process of contacting the polyisobutylene oil with clay and filtering is repeated.
Выход полимера от загружеиного изобутилеиа составл ет 60/о. № 122281- 2 - Фракционный состав полиизобутиленового масла приведен в таблиThe polymer yield from the primed isobutylene is 60 / o. No. 122281- 2 - Fractional composition of polyisobutylene oil is given in table.
