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, R1 is a methyl group or an ethyl group.)
本发明涉及[1]一种生产1-(2-t-丁基环己氧基)-2-烷醇的方法,包括以下步骤:将含有式(1)代表的1-(2-t-丁基苯基氧基)-2-烷醇的原料混合物调节至pH值为7.5至10.0,并在
钯催化剂(A)和含有一种或多种选自
钌、
铑、
铂和
镍的成员的
金属催化剂(B)存在下将其氢化;以及[2]一种含有通过上述方法获得的1-(2-t-丁基环己氧基)-2-烷醇的香
水组合物。本发明提供了一种高效生产 1-(2-t-丁基环己氧基)-2-烷醇的方法,这种烷醇具有较高的反式异构体含量和浓郁的木香或琥珀香味,可用作香
水原料,同时还具有极佳的香气持久性。
(式中,R1 为甲基或乙基)。
