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 a temperature between 400 DEG C and 600 DEG C followed by an equilibration of the resultant intermediate in either the gas phase or liquid phase at a temperature between 180 DEG C and 375 DEG 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.
