    摘要： A process is described for reacting "myrac aldehyde" having the structure: ##STR1## (which structure is representative of a mixture of two compounds, one where the carboxaldehyde is in the "4" position and the other wherein the carboxaldehyde is in the "5" position) with an acid hydrating agent at a temperature of from 0.degree. up to 120.degree. C, to produce a mixture containing a major proportion of 4-(4'-methyl-4'-hydroxyamyl)-.DELTA..sup.3 -cyclohexene carboxaldehyde and a minor proportion of 3-(4'-methyl-4'-hydroxyamyl)-.DELTA..sup.3 -cyclohexene carboxaldehyde (otherwise termed "Lyral") having the structure: ##STR2## and a minor proportion of 3-(4'-methyl-4'-hydroxyamyl)-.DELTA..sup.3 -cyclohexene carboxaldehyde having the structure: ##STR3## which mixture possesses a sweet, lilac-lily aromatic odor and isolating a mixture of the two carboxaldehydes. The products produced by the aforementioned process are useful in various aspects of perfumery.

    摘要翻译： 描述了具有以下结构的“烟酰醛”的反应方法：（该结构代表两种化合物的混合物，其中甲醛处于“4”位，另一种是甲醛在“ 5“位置）与酸性水合剂在0℃至120℃的温度下反应，生成含有主要比例的4-（4'-甲基-4'-羟基戊基）-Δt3 3-环己烯甲醛的混合物 和较小比例的具有以下结构的3-（4'-甲基-4'-羟基戊基）-TATA-环己烯甲醛（另外称为“Lyral”）和少量的3-（4'-甲基 -4'-羟基戊基） - 具有以下结构的DELTA 3-环己烯甲醛：该混合物具有甜味的丁香芳香气味，并分离出两种羧醛的混合物。 通过上述方法生产的产品在香料的各个方面都是有用的。
