(57) [Summary] [Structure] trans and / or cis-3,7-dimethyl-2,6- Octadiene nitrile in the presence of a basic catalyst, 50-25 A method of heating to 0 ° C. for isomerization, and a method of adjusting the trans isomer / cis isomer ratio thereby. [Effect] The trans isomer / cis isomer ratio can be easily adjusted in a short time. Moreover, it can be inexpensively adjusted to a preferable range for use as a fragrance. |
