摘要： An alicyclic unsaturated alcohol (for example, tetrahydrobenzyl alcohol) having the purity of 99% by weight or more, the water content of 0.1% by weight or less and the acid value of 0.1 mg KOH/g or less can be produced, with high selectivity, by hydrogenating using an unsaturated cyclic aldehyde having the acid value of 10 mg KOH/g or less as a raw material; terminating the hydrogenation in the conversion of 70 to 99.8%; and rectifying the reaction product containing the unreacted unsaturated cyclic aldehyde. The high purity alicyclic unsaturated alcohol is useful as raw material chemicals for synthesizing drugs, agricultural chemicals, perfumes, and dyes etc.
