摘要：An alicyclic unsaturated alcohol (for example, tetrahydrobenzyl alcohol) havingthe purity of 99% by weight or more, the water content of 0.1% by weight or less and theacid value of 0.1 mg KOH/g or less can be produced, with high selectivity, byhydrogenating using an unsaturated cyclic aldehyde having the acid value of 10 mgKOH/g or less as a raw material; terminating the hydrogenation in the conversion of 70 to99.8%; and rectifying the reaction product containing the unreacted unsaturated cyclicaldehyde. The high purity alicyclic unsaturated alcohol is useful as raw material chemicalsfor synthesizing drugs, agricultural chemicals, perfumes, and dyes etc.
