| titleOfInvention | Continuous distillation purification method of ethylidenetetracyclododecene |
| abstract | (57) [Summary] [PROBLEMS] Crude ethylidenetetracyclododecene (crude Ed) The present invention provides a simple purification method capable of obtaining EdTCD in high yield and high purity by distilling a TCD) fraction. SOLUTION: A reaction liquid obtained by heating and mixing cyclopentadiene and / or dicyclopentadiene and 5-ethylidene-2-norbornene (EBH) is distilled to obtain a crude EdTCD fraction, and then the above fraction is obtained. Is supplied to a distillation purification column, and continuous distillation is performed by selecting conditions such that the amount of EBH in the purified EdTCD fraction obtained from the distillation purification column is less than 1%. |
