| titleOfInvention | Method for preparing bis (4-tert-butyl benzyl) sulfide product |
| abstract | The invention discloses a method for preparing a bis (4-tert-butyl benzyl) sulfide product, which belongs to the technical field of preparation of antioxidants of medical intermediates and polymers. Wherein, the raw material ratio is: p-tert-butyl benzyl chloride: sodium sulfide (molar ratio) =1: 0.5-0.9; p-tert-butyl benzyl chloride: an organic solvent (mass ratio) =1: 0.8-1.6; p-tert-butyl benzyl chloride: emulsifier (mass ratio) =1: 0.008-0.033; p-tert-butyl benzyl chloride: phase transfer catalyst (mass ratio) =1: 0.008-0.033. The reaction temperature in the reaction process is 50-70 ℃, the reaction time is 150-240 minutes, and high raw material conversion rate and product yield are obtained. |
