Procedure

Next, in an atmospheric reaction tube of a flow type made of quartz and having an outer diameter of 20 mm and a length of 500 mm, 20 g of γ-alumina (N612, manufactured by Nikki Chemical Co., Ltd.) was placed. The dehydration was conducted at a reaction temperature of 285° C. and a weight hourly space velocity (WHSV) of 1.1 hr−1, so that a dehydration product of 2-hydroxymethyl-3-methylbicyclo[2.2.1]heptane containing 2-methylene-3-methylbicyclo[2.2.1]heptane and 2,3-dimethylbicyclo[2.2.1]hept-2-ene was obtained in an amount of 490 g.
