Изобретение относится к органической химии, конкретно к способу получения изопропилбензола. Изопропилбензол находит применение как исходное сырье для производства фенола, альфа-метилстирола и др. продуктов, для получения гербицидов, эпоксидных смол, фенолформальдегидных полимеров, полиамидных волокон. Для повышения чистоты продукта предложено использовать отходы алюминиевой промышленности и процесс проводить при 45 - 55oС. Способ позволяет пользоваться катализатором без предварительной обработки, проводить реакцию без охлаждения при одновременном смешивании исходных веществ, получая продукт высокой чистоты.The invention relates to organic chemistry, specifically to a method for producing isopropylbenzene. Isopropylbenzene is used as a feedstock for the production of phenol, alpha-methylstyrene and other products, for the production of herbicides, epoxies, phenol-formaldehyde polymers, polyamide fibers. To improve the purity of the product, it is proposed to use aluminum waste and the process is carried out at 45 - 55 o C. The method allows you to use the catalyst without pre-treatment, to carry out the reaction without cooling while mixing the starting materials, obtaining a product of high purity.
