The invention discloses a novel synthesis method of chlorolucanthone, and belongs to the technical field of chemical engineering. The method comprises the following steps: firstly, adding a sodium hydrosulfide solution into a hydrogen sulfide generator, then dropwise adding an acid into the hydrogen sulfide generator, and guiding generated gas into a preheated pipeline reactor; pumping preheated p-dichlorobenzene into the pipeline reactor, reacting the p-dichlorobenzene with hydrogen sulfide gas, cooling a reaction product to obtain liquid and gas, and rectifying and purifying the liquid to obtain mercaptochlorobenzene; secondly, adding a reaction solvent and an alkali into a flask, stirring, adding mercaptochlorobenzene and o-chlorobenzoic acid, carrying out a reflux reaction, and carrying out aftertreatment after the reaction is finished so as to obtain an intermediate 2-carboxyl-4'-chlorodiphenyl sulfide; and finally, adding 2-carboxyl-4'-chlorodiphenyl sulfide into concentrated sulfuric acid, carrying out an intramolecular cyclization dehydration reaction, and purifying after the reaction is ended so as to obtain the target product. The method disclosed by the invention is simple and convenient to operate, mild in reaction condition, clean and environment-friendly, and high in product yield and purity.
