Twenty nitriles, including saturated and unsaturated aliphatic, araliphatic, and aromatic nitriles, were prepared from the corresponding aldehydes, commonly used as flavors or fragrances. The aldehydes were converted to aldoximes first, which then underwent dehydration by treatment with oxalyl chloride in the presence of a catalytic amount of dimethyl sulfoxide. The nitriles were obtained in high yields in most cases. The odor characteristics of the nitriles obtained were evaluated by GC‐O. The nitriles present varied characteristic odors, which are usually distinct from those of the corresponding aldehydes.

醛类腈的制备及气味特征

由通常用作香料或香精的相应醛制得了二十个腈，包括饱和和不饱和脂族，芳脂族和芳族腈。醛首先被转化为醛肟，然后在催化量的二甲亚砜存在下，通过用草酰氯处理进行醛的脱水。在大多数情况下，腈的收率很高。所得腈的气味特性通过GC-O进行了评估。腈具有各种特征性气味，通常不同于相应的醛。
