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.
本文披露了一种制备富含特定几何异构体的1,2,4-三乙烯环己烷的方法。该方法涉及将1,5,9-环十二烯在400°C至600°C的温度下进行热异构化,然后在气相或液相中在180°C至375°C的温度和0.101 kPa至1,013 kPa的压力下平衡所得的中间体。还披露了富含特定几何异构体的1,2,4-三乙烯环己烷组合物。
