PRODUCTION OF BICYCLO[2.2.1]HEPTANE DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To produce a bicyclo[2.2.1]heptane derivative having high traction coefficient at high temperature and excellent low-temperature viscosity characteristics by dimerizing a raw material compound at or below a specific temperature in the presence of an acid catalyst and hydrogenating the product in the presence of a hydrogenation catalyst at a temperature within a specific range. SOLUTION: The objective compound of the formula ((m) is 2 or 3; (n) is 1 or 2) can be produced by dimerizing a bicyclo[2.2.1]heptane ring compound substituted with methylene group and methyl group (e.g. 2-methylene-3- methylbicyclo[2.2.1]heptane or 3-methylene-2-methylbicyclo[2.1.1]heptane) and/or a bicyclo[2.2.l]heptene ring compound substituted with methyl group (e.g. 2,3- dimethylbicyclo[2.2.1]hept-2-ene) in the presence of an acid catalyst (e.g. a Lewis acid) at <=60 deg.C and hydrogenating the produced dimer in the presence of a hydrogenation catalyst (e.g. nickel-based catalyst) at 200-300 deg.C.
