Preparation process of photoinitiator 2-/4-isopropyl thioxanthone

The invention provides a preparation process of a photoinitiator 2-/4-isopropyl thioxanthone, which comprises the following steps: by taking dithiobenzoic acid as a raw material, and carrying out substitution condensation on an intermediate 2-chloromercaptobenzoyl chloride and isopropyl benzene under an anhydrous condition by taking a boron trifluoride complexing agent as a condensing agent; after condensation, carrying out reduced-pressure solvent removal, water washing treatment and high-vacuum distillation to obtain a 2-/4-isopropyl thioxanthone crude product, and refining the crude product to obtain a 2-/4-isopropyl thioxanthone refined product. The method has the advantages that generation of three wastes is greatly reduced, the production cost is reduced, the sewage treatment pressure is reduced, the production efficiency is improved, and the method is suitable for mass production of products.
