First pass hydrogen sulfide into potassium hydroxide ethanol solution to saturation, stir and cool to 10-15 ℃, and add benzoyl chloride dropwise. Filter out the potassium chloride precipitated by the reaction, slowly add solid iodine, and keep it at 10-15 ℃. During the iodization process, dibenzoyl disulfide precipitates out.
