| titleOfInvention | A kind of method for preparing divinylbenzene as raw material with ethanol and ethylbenzene |
| abstract | The invention discloses a method for preparing divinylbenzene from ethanol and ethylbenzene as raw materials. The method comprises the following steps: sequentially loading catalyst 1 in two beds of a fixed-bed reactor: CuFe 2 O 4 supported Pt particles, and catalyst 2: Cu-Fe/ZSM-5 molecular sieve or Mn-Fe/ZSM-5 molecular sieve; inert packing and inert gas are arranged between the two beds; in the atmosphere of inert gas, ethylbenzene and ethanol are passed into the fixed bed for reaction In the reactor, the reaction temperature, reaction pressure and space velocity are set, and after the reaction is completed, divinylbenzene is condensed to obtain divinylbenzene. The present invention adopts a mixed catalyst, in a fixed bed reactor, the catalyst 1 and the catalyst 2 are respectively filled with two beds, and the alkylation and dehydrogenation series reactions are carried out in the same reactor, which significantly improves the intermediate level of the divinylbenzene mixture. , para-monomer content; the reaction temperature of the present invention is 250-400 DEG C, the reaction pressure is low pressure, and the total energy consumption of the reaction is low; the catalyst of the present invention has high catalytic activity, good selectivity, and high yield of divinylbenzene. |
