Method for synthesizing 4,4'-thiodibenzenethiol

The invention discloses a method for synthesizing 4,4'-thiodibenzenethiol. The method comprises the following steps: by taking phenyl sulfide as an initial raw material, reacting with chlorosulfonic acid so as to obtain 4,4'-bis(chlorosulfonyl)phenyl sulfide; reducing with glacial acetic acid so as to obtain 4,4'-bis(ethanethioate)phenyl sulfide under the actions of red phosphorus and iodine; hydrolyzing so as to obtain crude 4,4'-thiodibenzenethiol; and finally, recrystallizing, thereby obtaining the high-quality 4,4'-thiodibenzenethiol. According to the method disclosed by the invention, raw materials are easily available, the process is advanced and the industrial production is convenient.
