UNSATURATED ALIPHATIC PRIMARY AMINE AND PROCESS FOR PRODUCTION THEREOF

Disclosed is a process for producing an unsaturated aliphatic primary amine which can prevent the by-production of a saturated aliphatic primary amine, can yield a product having no turbidness or no precipitate, and can produce an unsaturated aliphatic primary amine having a low coagulation point with good efficiency. Also disclosed is an unsaturated aliphatic primary amine produced by the process. A process for producing an unsaturated aliphatic primary amine comprising the step of performing the hydrogen reduction of an unsaturated aliphatic nitrile having 16 to 22 carbon atoms with a hydrogenation catalyst in the presence of ammonia, wherein the hydrogen reduction is performed under the conditions where an aromatic carboxylic acid amide is added in an amount of 0.01 to 1.0 part by mass based on 100 parts by mass of the unsaturated aliphatic nitrile and the ratio of the fractional pressure of ammonia to that of hydrogen (ammonia)/(hydrogen)] is adjusted within the range from 8/2 to 6/4; and an unsaturated aliphatic primary amine produced by the process, which has an amine conversion rate as defined by the formula (1) of 95% or higher, and has an iodine value retention rate as defined by the formula (2) of 95% or higher. [Formula 101 (1) AA Amine conversion rate (%) BB (found amine value of unsaturated aliphatic primary amine) CC (calculated amine value of the amine) [Formula 11] (2) DD Iodine value retention ratio (%) EE (iodine value of unsaturated aliphatic primary amine) x (molecular weight of the amine) FF (iodine value of unsaturated aliphatic nitrile) x (molecular weight of the nitrile)
