    • The present invention provides a liquid phase process for the acylation of aromatic compound by an acylating agent of the formula (R5R6R7)—Y—Z to obtain the corresponding acylated compound using a solid catalyst comprising a metal oxide of the formula AOx with or without a catalyst support, wherein A is a metallic element selected from Ga, In, Ti, Fe and a mixture of two or more thereof, and x is the number of oxygen atoms required to fulfil the valance requirement of A, wherein the catalyst is pretreated with a dry gas comprising a hydrogen halide in the presence or absence of the aromatic compound to be acylated, contacting the hydrogen halide pretreated catalyst with a liquid reaction mixture comprising the aromatic compound and the acylating agent, cooling the reaction mixture, removing the catalyst from the reaction mixture and then separating the reaction products from the reaction mixture.
    • 本发明提供了通过式(R5R6R7)-YZ的酰化剂使芳族化合物酰化的液相方法,以使用包含具有或不具有催化剂载体的式AOx的金属氧化物的固体催化剂获得相应的酰化化合物 其中A是选自Ga,In,Ti,Fe及其两种或更多种的混合物的金属元素,x是满足A的价格要求所需的氧原子数,其中催化剂用干燥 在待酰化的芳族化合物存在或不存在下,将卤化氢气体与卤化氢预处理的催化剂与包含芳族化合物和酰化剂的液体反应混合物接触,冷却反应混合物,从反应混合物中除去催化剂 然后将反应产物与反应混合物分离。
