Continuous production process of aromatic acyl chloride

The invention belongs to the technical field of chemical synthesis, and in particular relates to a continuous production process of aromatic acyl chloride. The continuous production process comprises the steps that aromatic carboxylic acid, thionyl chloride and a catalyst are added into a mixing tank for mixing; mixed materials enter into the top of a feed tank from the bottom of the mixing tank; the materials in the feed tank is pressed into the top of a reaction still A from the bottom of the feed tank; the materials at the bottom of the reaction still A enter into the top of a reaction still B; the materials at the bottom of the reaction still B enter into the top of a reaction still C; materials which are fully reacted in the reaction still C enter into a tubular reactor; nitrogen is introduced into the tubular reactor; a solvent is removed; the materials enter into a gas-liquid separator for separation, purification is performed to obtain the aromatic acyl chloride. The continuous production process provided by the invention has the characteristics of being simple in process, continuous and efficient, the reaction period is greatly shortened, and the production efficiency is improved; the continuous production process is conducive to steaming out the redundant solvent in reaction liquid, avoiding the occurrence of side reaction, and reducing the generation of waste in a distillation process.
