(54) СПОСОБ РЕГЕНЕРАЦИИ КАТАЛИТИЧЕСКОГО КОМПЛЕКСА НА ОСНОВЕ ХЛОРИСТОГО АЛЮМИНИЯ ДЛЯ АЛКИЛИРОВАНИЯ БЕНЗОЛА(54) METHOD FOR REGULATING CATALYTIC COMPLEX BASED ON ALUMINUM CHLORINE FOR ALKYLATION OF BENZENE

килате, разлагают таким количеством воды, чтобы образовались основные хлориды алюмини , разложение ведут при интенсивном механическом перемешивании алкилата, Кгзтализатора и воды, чтобы частично- выделилс хлористый водород . По окончании реакции нижний водный слой, содержащий основной хлорид алюмини , отдел ют от верхнего углеводородного и снова иснользуют в процессе алкилировани , Алкилат подвергают дальнейшей отмывке. Благодар интенсивному перемешиванию частички катализатора равномерно распредел ютс в углеводороде и равномерно реагируют с водой.kilate is decomposed in such an amount of water that basic aluminum chlorides are formed, decomposition is carried out with intensive mechanical stirring of the alkylate, crystallization catalyst and water, so that hydrogen chloride is partially separated. At the end of the reaction, the lower aqueous layer containing the basic aluminum chloride is separated from the upper hydrocarbon and again used in the alkylation process. The alkylate is subjected to further washing. Due to the intensive mixing, the catalyst particles are evenly distributed in the hydrocarbon and react uniformly with water.
Прибавление нужного количества воды к реакционной массе не приводит к образованию гидроокиси алюмини , как это происходит в обычных услови х, В то же врем в результате выделени га.эообразного хлористого водорода образуютс основные хлориды алюмини .The addition of the required amount of water to the reaction mass does not lead to the formation of aluminum hydroxide, as is the case under normal conditions. At the same time, basic chlorides of aluminum are formed as a result of the release of a gaseous hydrogen chloride.
Пример. К 1ОО мл алкилата процесса производства этилбензола, содержащего после отстойника 5 г каталитического комплекса на основе хлористого алюмини , медленно добавл ют 15 мл воды при интенсивном перемешивании . По окончании выделени хлористого водорода отдел ют нижний водный слой, содержащий оксихлориды алюмини оотношенне комплекс: вода 1:3,Example. To 1OO ml of alkylate of the ethylbenzene production process, which contains 5 g of the catalytic complex based on aluminum chloride after the settling tank, 15 ml of water are slowly added with vigorous stirring. At the end of the evolution of hydrogen chloride, the lower aqueous layer is separated, containing aluminum oxychlorides, the relative complex: water 1: 3,

П р и м е р 2. 10 г отработанного комплекса на основе ЛР СС и этилбензола заливают в реактор, затем поЬпвл ют 100 мл диэтипбензольной фракции и при интенсивном перемешивании равномерно подают 10 мл воды. Полученный водный раствор оксихлорида алюмини содержит 200 г/л АС,, О , Соотношение комплекс: вода 1:1,PRI mme R 2. 10 g of the spent complex based on LR SS and ethylbenzene are poured into the reactor, then 100 ml of the diethybenzene fraction are poured and 10 ml of water are evenly fed with vigorous stirring. The resulting aqueous solution of aluminum oxychloride contains 200 g / l AU, O, the ratio of the complex: water 1: 1,
