摘要 <p>The present invention relates to [1] a method of producing a 1-(2-t-butylcyclohexyloxy)-2-alkanol including a step of adjusting a raw material mixture containing a 1-(2-t-butylphenyloxy)-2-alkanol represented by the formula (1) to a pH of from 7.5 to 10.0 and hydrogenating it in the presence of a palladium catalyst (A) and a metal catalyst (B) containing one or more kinds of members selected from ruthenium, rhodium, platinum, and nickel; and [2]a perfume composition containing a 1-(2-t-butylcyclohexyloxy)-2-alkanol obtained by the foregoing method. The present invention provides a method of efficiently producing a 1-(2-t-butylcyclohexyloxy)-2-alkanol having a high trans-isomer content and a strong woody or amber-like fragrance as a perfume material and also having excellent persistence of aroma. (In the formula, R 1 is a methyl group or an ethyl group.)</p>
