Description

етс  (расход хлористого алюмини  на тонну кумола составл ет 15-20 кг).(consumption of aluminum chloride per ton of cumene is 15-20 kg).

Прнмер. В колбу с мешалкой, обратным холодильником и термометром ввод т 26,67 г 0,2 М А1С1з и 44,48 г 0,15 М октаметилциклотетрасилоксана . Смесь нагревают при перемешивании 10 ч при температуре 120°С. По окончании реакции продукты реакции , представл ющие собой смесь кристаллов с жидкой фазой, были расфракционированы в вакууме. При этом получают 17,53 г фракции с температурой кипени  30-116°С (10 мм) и 34,24 г фракции с температурой кипени  116-193°С (10 мм), полностью закристаллизовавшейс  в приемнике . После вторичного тш,ательного фракционировани  и еублимации кристаллической фракции получают 28,12 г белых кристаллов с температурой плавлени  152-Prnmer. 26.67 g of 0.2 M AlCl3 and 44.48 g of 0.15 M octamethylcyclotetrasiloxane are introduced into the flask with a stirrer, a reflux condenser and a thermometer. The mixture is heated with stirring for 10 hours at a temperature of 120 ° C. At the end of the reaction, the reaction products, which are a mixture of crystals with a liquid phase, were disfractionated in vacuum. 17.53 g of a fraction with a boiling point of 30-116 ° C (10 mm) and 34.24 g of a fraction with a boiling point of 116-193 ° C (10 mm), completely crystallized in the receiver, are obtained. 28.12 g of white crystals with a melting point of 152- are obtained after the secondary solid phase fractionation and elimation of the crystalline fraction.

153°С, легко сублимирующихс  под вакуумом . Вещество хорощо раствор етс  в воде , в спирте и в серном эфире, в бензоле растворимо только при нагревании. Дл  свежесиптезпрованпого вещества сделан элементный анализ: С8П240бС15Si4Al3 .153 ° C, easily subliminated under vacuum. The substance is horosho soluble in water, in alcohol and in sulfuric ether, in benzene it is soluble only when heated. For freshly synthesized substance, elemental analysis was performed: S8P240bS15Si4Al3.
