| titleOfInvention | Method for synthesizing ethylbenzene from ethanol and benzene |
| abstract | The invention relates to a method for synthesizing ethylbenzene from ethanol and benzene. The method is used for mainly solving the problems that the traditional ethylbenzene production process must depend on ethylene as a raw material and has high raw material cost. The problems are well solved by adopting the technical scheme as follows: the method comprises the following steps: (a) the benzene and the ethanol enter an alkylation reactor filled with a ZSM-5 nano-scale molecular sieve catalyst to be reacted under a gaseous phase condition according to the mol ratio of (2-8):1 so that a mixture 103 including benzene, ethylbenzene, diethylbenzene and water is obtained; (b) the mixture 103 sequentially passes through a benzene recovery tower, an ethylbenzene recovery tower and a poly-ethylbenzene recovery tower so that the water, the benzene, the ethylbenzene and the diethylbenzene in the mixture are separated; and (c) a part of the separated benzene and the diethylbenzene enter an alkyl transfer reactor under a gaseous phase condition according to the weight ratio of (2-10):1 and are in contact with the ZSM-5 molecular sieve catalyst to carry out alkyl transfer reaction so that the ethylbenzene is generated. According to the method, the ethylene is replaced by ethanol as a raw material; the ethanol and the benzene are used for synthesizing the ethylbenzene; the raw material cost is low; and the method can be applied in the industrial production of the ethylbenzene. |
