Method for continuously producing aromatic ketone

The invention discloses a method for continuously producing aromatic ketone in the technical field of aromatic ketone production, and the method comprises the following steps: 1. adding aromatic hydrocarbon, aromatic acyl chloride and a catalyst into a pre-reactor, and uniformly mixing to prepare a reaction solution; 2, putting the reaction solution into a raw material tank, pumping the reaction solution in the raw material tank into a tubular reactor by using a metering pump, carrying out a heating reaction, carrying out gas-liquid separation on HCl gas generated by the reaction, absorbing the HCl gas with water to prepare hydrochloric acid, and cooling a liquid material after the liquid material enters a receiving tank under the action of pressure; and step 3, carrying out alkali washingneutralization on the cooled liquid material to remove excessive aromatic hydrocarbon in the liquid material, and finally performing reduced pressure rectification on the liquid material to obtain the aromatic ketone.
