Изобретение относитс к способу получени изопропилхлорида, используемого в процессе получени фенола и ацетона в качестве активатора каталитического комплекса.The invention relates to a process for the preparation of isopropyl chloride used in the process of producing phenol and acetone as an activator of a catalytic complex.
Известен способ получени изопропилхлорида гидрохлорированием пропилена в паровой фазе при 80-120°С в присутствии катализатора - хлорида теллура. В качестве гидрохлорирующего агента используют концентрированную сол ную кислоту. Выход целевого продукта 90% l.A method of producing isopropyl chloride by hydrochlorinating propylene in the vapor phase at 80-120 ° C in the presence of a catalyst, tellurium chloride, is known. Concentrated hydrochloric acid is used as the hydrochlorinating agent. The yield of the target product is 90% l.
Недостатком известного способа вл етс сложность проведени процесса вследствие использовани концентрированной сол ной кислоты, вызывающей коррозию аппаратуры. Кроме .того, катализатор требует частой регенерации , что Б целом усложн ет технологию процесса.The disadvantage of the known method is the difficulty of carrying out the process due to the use of concentrated hydrochloric acid, which causes corrosion of the apparatus. In addition, the catalyst requires frequent regeneration, which generally complicates the process technology.
С целью упрощени процесса предлагаетс использовать в качестве каталиэатора окись хрома в количестве 1-10 вес.%На носителе - двуокиси кремни и вести процесс при 100-140 In order to simplify the process, it is proposed to use chromium oxide in the amount of 1-10% by weight as a catalyst. On the carrier is silicon dioxide and to carry out the process at 100-140
Лучше всего использовать в качестве катализатора 1-5 вес.% окиси хрома на двуокиси кремни и вести процесс при мол рном соотношении мезкДУ пррпиленом и хлористым водородом 1:(3-7) .It is best to use 1–5 wt.% Chromium oxide on silicon dioxide as a catalyst and carry out the process at a molar ratio of mecDa of prprylene and hydrogen chloride 1: (3–7).
Процесс провод т в реакторе проточного типа при атмосферном давлении , подава исходные газы после соответствующей очистки и осушки в реактор ( г 80 мм, d 20-22 мм). Врем контакта 1-20 сек, количество кaтализатора 5 см.The process is carried out in a flow-type reactor at atmospheric pressure, feeding the source gases after appropriate cleaning and drying into the reactor (g 80 mm, d 20-22 mm). The contact time is 1-20 seconds, the amount of catalyst is 5 cm.
Продукты реакции после охлаждени при 0°С и промывки от хлористого водорода подают в систему улавливани и в г 13ометр.The reaction products, after cooling at 0 ° C and washing from hydrogen chloride, are fed to the trapping system and to the 13 meter g.
йнализ продуктов реакции осуществл ют методами хроматографии,, ИКи масс-спектроскопии. Полученные результаты приведены в таблице. Analysis of the reaction products is carried out by chromatography, IR, and mass spectroscopy. The results are shown in the table.
Анализ показывает, что в конденсате и в газовой фазе содержитс одинThe analysis shows that in the condensate and in the gas phase contains one

При 140 С выход целевого продукта уменьшаетс до 80%.At 140 ° C, the yield of the desired product is reduced to 80%.
