Zusammenfassung: | The invention relates to a green catalytic synthesis method of diphenylmethane. According to the invention, benzene and benzyl chloride which are used as raw materials undergo a Fradel-Crafts alkylation reaction at the reaction temperature of 100-200 DEG C for 1-8 hours so as to obtain the product diphenylmethane, wherein the ratio of benzene to benzyl chloride is 2:1-20:1. The method provided by the invention is a diphenylmethane catalytic synthesis process with simple reaction technique and little pollution. |
