[Problem] The present invention provides: a composition for imparting a cooling sensation, which contains 3-menthoxy propanol; and a method for producing 3-menthoxy propanol with high selectivity and high yield using 3-menthoxy-1,2-epoxypropane as a starting material.
[Solution] The present invention relates to: a method for producing 3-menthoxy propanol with high selectivity and high yield by performing catalytic hydrogenation of 3-menthoxy-1,2-epoxypropane in the presence of a heterogeneous metal catalyst such as a cobalt, a ruthenium catalyst or a nickel catalyst; and an excellent composition for imparting a cooling sensation, which contains a mixture of 3-menthoxy-1-propanol and 1-menthoxy-2-propanol.
[问题]本发明提供了:一种用于赋予冷却感的组合物,其中含有 3-薄荷氧基丙醇;以 3-薄荷氧基-1,2-环氧丙烷为起始原料,以高选择性和高产率生产 3-薄荷氧基丙醇的方法。
[解]本发明涉及:一种在异质金属催化剂(如钴催化剂、钌催化剂或镍催化剂)存在下,通过对 3-menthoxy-1,2-epoxypropane 进行催化氢化反应,生产具有高选择性和高产率的 3-menthoxy-丙醇的方法;以及一种具有冷却感的优良组合物,该组合物含有 3-menthoxy-1-丙醇和 1-menthoxy-2-丙醇的混合物。
