| titleOfInvention | Method for producing isopropylbenzene |
| abstract | The invention relates to a method for producing isopropylbenzene by hydrogenolysis of alpha,alpha-dimethyl benzyl alcohol. The method is used for mainly solving the problems of low activity of catalyst, poor stability and serious environmental pollution in the isopropylbenzene production process in the prior art. The problem is well solved by adopting the technical scheme as follows: the method disclosed by the invention comprises the steps of contacting the alpha,alpha-dimethyl benzyl alcohol and hydrogen as raw materials with a catalyst for reaction to generate the isopropylbenzene under the conditions as follows: the mol ratio of the hydrogen to the benzyl alcohol is 1:(0.05-1); the reaction temperature is 120-220 DEG C; the reaction pressure is 0.2-3.0 MPa; and the liquid airspeed is 0.5-10.0 h<-1>, wherein the used catalyst comprises the following components according to percentage by weight: (a) 10.0-45.0% of CuO; (b) 5.0-25.0% of NiO; (c) 25.0-70.0% of A12O3; and (d) 3.0-10.0% of at least one selected from MgO, CaO, CeO2, BaO and ZrO2. The method for producing the isopropylbenzene disclosed by the invention can be applied to industrial production for preparing the isopropylbenzene by the hydrogenolysis of the alpha,alpha-dimethyl benzyl alcohol. |
