METHOD OF PRODUCING ISOPROPYLBENZENE Russian patent published in 2013 - IPC C07C15/85 C07C2/68 

FIELD: chemistry.

SUBSTANCE: invention relates a method of producing isopropylbenzene. The method involves alkylating benzene with propylene in the presence of an aluminium trichloride-based catalyst complex by feeding dried benzene charge material, polyalkylbenzenes, propylene, catalyst complex and recycled catalyst complex into the alkylation reactor in turbulent conditions. The method is characterised by that mixing the dried benzene charge material and polyalkylbenznes with propylene is carried out in a vortex mixer before feeding into the manifold of the alkylation reactor, and the recycled catalyst complex is fed into the middle part of the alkylation reactor.

EFFECT: use of the present invention increases selectivity of the process, increases output of the end product, reduces consumption of raw materials: benzene, propylene, aluminium trichloride-based catalyst complex.
