Zusammenfassung:Disclosed herein is a process for making 1,2,4-trivinylcyclohexane that is enriched in a particular geometric isomer. The process involves the thermal isomerization of 1,5,9-cyclododecatriene at temperature between 400° C. and 600° C. followed by an equilibration of the resultant intermediate in either the gas phase or liquid phase at temperature between 180° C. and 375° C. and at pressures ranging from 0.101 kPa to 1,013 kPa. Also disclosed are 1,2,4-trivinylcyclohexane compositions that are enriched in a particular geometric isomer.
