Description
Изобретение относитс к способу получени ацилированных ароматических углеводо (родов.This invention relates to a method for producing acylated aromatic carbohydrates (genera.
Известен способ получени ацилированных ароматических углеводородов при взаимодействии ароматических углеводородов с ацилхлоридами в присутствии катализатора - галогенидов металлов, например AlCls.A method of producing acylated aromatic hydrocarbons by reacting aromatic hydrocarbons with acyl chlorides in the presence of a catalyst — metal halides, such as AlCls, is known.
Одна.ко выход целевого продукта недостаточно высок.However, the yield of the target product is not high enough.
С целью .повышени выхода целевого продукта предлагаетс в качестве катализатора использовать комплексное соединение на основе хлоридов металлов и солей четырехзамещенного афгмони общей формулы.In order to increase the yield of the target product, it is proposed to use as a catalyst a complex compound based on metal chlorides and salts of tetra-substituted afmonium of the general formula.

The aromatic hydrocarbon, acetyl chloride and catalyst, taken in a molar ratio of 10: 1: 0.05 or 10: 1: 0.1, are heated in reverse to an M condenser to absorb the released hydrogen chloride. At the end of the evolution of hydrogen chloride or a predetermined reaction time, the reaction mixture is poured from the catalyst, washed with water to remove traces of the catalyst. And dispersed, the "unreacted starting materials and products" are separated. The yield of the products of reactants and their characteristics are given in the table.
