2-乙烯基环十二烷-1-酮 、 2-cis-Ethylidencyclododecanon 以respectively provided that the average relative volatility of 2-(E)-ethylidenecyclododecanone (1-a)的产率得到2-ethylidenecyclododecanone
A process for producing 2-vinylcyclododecanone, the process comprising isomerizing 2-ethylidenecyclododecanone represented by the following formula (1):
wherein the wave line shows that the double bond is a Z-isomer, an E-isomer or a mixture of an E-isomer and a Z-isomer; in the presence of a catalyst and separating 2-vinylcyclododecanone represented by the following formula (2) from the reaction product by fractionation:
2-Vinylcyclododecanone can be produced using 2-ethylidenecyclododecanone, which can be manufactured simply from cyclododecanone in a high yield through no chlorination, without using any solvent having safety problems in a high yield by using a simple process involving neither washing nor solvent recovery.
