Kinetics of alkylation of benzene with propylene in the presence of dimethyldichlorosilane

The kinetics of alkylation of benzene with propylene in the presence of dimethyldichlorosilane at 130, 150, and 170°C and 1.2–1.8 MPa was investigated. Kinetic equations were derived for a three-stage scheme of this process and its kinetic parameters were calculated. The promoting effect of water on the catalyst at a content in the reaction mixture of under 0.4 mole % was established. Transalkylation of benzene with di- and triisopropylbenzenes was investigated.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 6, pp. 39–42, November– December, 2004
