FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing a mixture of hexacyclo[8.4.0.02,7.03,14.04,8.09,13]tetradecene-5 and hexacyclo[6.6.0.02,6.05,14.07,12.09,13]tetradecene-3 through isomerisation of binor-S under the effect of phosphoric anhydride P2O5 (P4O10), characterised by that the reaction is carried out in a dichloromethane medium at temperature ranging from 25 to 35°C with addition of aluminium oxide Al2O3 to P2O5 in the following ratio of reagents : [Al2O3]: [P2O5]: [binor-S]=0.2-0.3:0.2-0.3:1. Use of this method allows for 80% olefin output without using tetrachloromethane.
EFFECT: reduced energy consumption, duration of reaction and reduced consumption of P2O5.
