Abstract RU 2485085 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing styrene by catalytic conversion of the corresponding acetophenone in a flow reactor. The method is characterised by that the process is carried out in a supercritical two-component solvent using a heterogeneous granular catalyst - aluminium oxide Al₂O₃.

EFFECT: use of the present method enables to obtain styrene with high output continuously over a contact time of several minutes.
