FIELD: chemistry.
SUBSTANCE: linear sterol dimer (trans-1,3-diphenylbut-1-ene) is produced by sterol oligomerisation with ceolite catalyst added in solvent and characterised by that catalyst is Beta ceolite in N-form in amount 8-15 wt %. Reaction is enabled in chlorbenzene in ratio sterol:chlorbenzene=1:4 (vol) and temperature 100-115°C.
EFFECT: simplified linear sterol dimer production process.
