| titleOfInvention | A kind of preparation method of 1,1 diphenylethane |
| abstract | The invention discloses a kind of preparation method of 1,1 diphenylethane, comprise the following steps：A, at room temperature, styrene is mixed with alcohols accelerator, is passed through dry hydrogen chloride gas thereto, after reaction terminates, the vinylbenzene of 2 chlorine of intermediate 2 is obtained through washing, being evaporated under reduced pressure；B, at 0~80 DEG C, using Lewis acid or ionic liquid as catalyst, the vinylbenzene of 2 chlorine 2 is alkylated reaction 1,1 diphenylethane of synthesis with benzene.The beneficial effects of the invention are as follows：1,1 diphenylethane is synthesized through two-step reaction using styrene as raw material, compared with conventional method, raw material sources enrich, and product yield is high, and catalyst can repeatedly use, and the feature of environmental protection is good. |
