THE METHOD OF OBTAINING ALKYLBENZENES by alkylation of benzene with chloroparaffins at 60-70 ° C in the presence of a catalytic complex, based on aluminum chloride, forming aluminum metal, hydrogen chloride and toluene, using the capture of benzene from off-gases and returning it to a process that differs from in order to reduce the loss of benzene and the amount of catalyst used, the alkylation process is carried out at an elevated pressure of 1.1-2.5 atm, followed by trapping of benzene by absorption first with chloroparaffins When 40-60 ° C and a pressure of 1.1-2.5 atm, and then the catalyst complex at 55-654.
