METHOD FOR COMBINED SYNTHESIS OF LINEAR AND CYCLIC HOMO- AND CODIMERS OF STYRENE AND ALPHA-METHYLSTYRENE Russian patent published in 2011 - IPC C07C2/12 C07C15/12 C07C13/45 C07C2/42 B01J29/14

Abstract RU 2428407 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for combined synthesis of cyclic and linear homo- and codimers of styrene and α-methylstyrene via codimerisation of monomers in the presence of an acid catalyst, characterised by that the catalyst used is zeolite NiHY in amount of 5-30 wt % and the reaction takes place in chlorobenzene at temperature 80-130°C.

EFFECT: use of said method simplifies combined oligomerisation of styrene and α-methylstyrene.
