FIELD: chemistry.
SUBSTANCE: cyclic sterol dimer (cys- and trans-1-methyl-3-phenylindan) is produced by sterol oligomerisation with ceolite catalyst added in solvent characterised by that catalyst is ZSM-12 ceolite in N-form in amount 20-30 wt %. Reaction enabled in chlorbenzene in ratio sterol: chlorbenzene =1:2÷4 (vol.) and temperature 120-130°C.
EFFECT: simplified cyclic sterol dimer production process with higher yield.
