| production method | 25.09g of formaldehyde dimethyl thioacetal is dissolved in 50 ml of acetic acid, and 26.5 milliblade is added to 30% hydrogen peroxide solution with ice cold. The mixture was stirred at room temperature for 30 minutes, then 300 ml of dichloromethane was added and 60g of potassium carbonate was added to neutralize acetic acid. Filtration, the filtrate is dried with anhydrous sodium sulfate, and the solvent is evaporated. The residue is fractionated to obtain 22.41 grams of metamethylthionyl, ethylethylthionyl and phenylphenylthionyl can be prepared by a similar method, and they are all colorless liquids. |
