Abstract

1391298 Unbranched alkylbenzenes SOC ITALIANA RESINE SpA 1 Aug 1972 [17 Nov 1971] 35964/72 Heading C5E Process for the manufacture of alkyl benzenes with an unbranched paraffin chain containing from 9 to 15 carbon atoms, by partial chlorination of unbranched paraffins having from 9 to 15 carbon atoms per molecule; catalytic alkylation, by means of the chlorinated paraffins, of benzene in excess; and fractionation of the alkylation product, after separation of the catalyst, into the components of the mixture is characterized in that alkylation is carried out in the presence of an activated catalytic complex obtained by blending spent catalytic sludge discharged from the alkylation reactor with the products of a particular treatment of the high boiling fractions obtained in the alkylation, the quantities being regulated in such a way that 25 to 125 parts by weight of the products of the said treatment are blended with 100 parts by weight of the sludge, the treatment consisting essentially in supplying to a reactor maintained at a temperature comprised between 20‹ and 60‹ C., with contact times comprised between 1 and 10 hours, the high boiling by-products of alkylation, together with aluminium trichloride, hydrogen chloride and benzene, the rates of supply being so regulated that aluminium trichloride is present in quantities comprised between 2 and 4 parts by weight per 10 to 25 parts by weight of high boiling fractions, while the molar ratios of HCl : AlCl 3 and of benzene : AlCl 3 are at least 1 : 1.
