METHOD FOR MAKING CYCLIC STYRENE DIMERS

摘要

FIELD: chemistry. ^ SUBSTANCE: invention refers to method for making cyclic styrene dimers (cis- and trans-1-methyl-3-phenylindan) by oligomerising styrene with N-zeolite type Beta added in the solvent, differing that amount of Beta zeolite is 18-25 wt % with reaction performed in chlorbenzene in ratio styrene:chlorbenzene=1:4 (voi.) and temperature 115-130C. ^ EFFECT: simplified process for making cyclic styrene dimers. ^ 1 cl, 5 ex, 1 tbl
