The invention relates to economical and efficient methods for producing 2-methylene-3-methylbicyclo[2,2,1]heptane, 2,3-dimethylbicyclo[2.2.1]hept-2-ene and the like that are useful for materials of producing base oil of traction drive fluid for traction drive lubricating oil. The methods comprise reacting one or more C
3-4
acyclic olefins with cyclopentadiene and isomerizing the resulting bicyclo[2.2.1]heptene derivatives in the presence of an isomerization catalyst to give one or more bicyclo[2.2.1]heptane derivatives.
该发明涉及经济高效的方法,用于生产2-亚甲基-3-甲基双环[2,2,1]
庚烷、2,3-二甲基双环[2.2.1]庚-2-烯等材料,这些材料对于生产牵引驱动液的基础油具有用途。该方法包括将一个或多个C3-4无环烯烃与
环戊二烯反应,并在异构化催化剂的存在下异构化所得的双环[2.2.1]庚烯衍
生物,以得到一个或多个
双环[2.2.1]庚烷衍
生物。
