  • Unsaturated aliphatic primary amine and production method thereof
    Patent number: 7781618
    Abstract: The present invention relates to a method for producing an unsaturated aliphatic primary amine including subjecting an unsaturated aliphatic nitrile having 16 to 22 carbon atoms to hydrogen reduction in the presence of ammonia using a hydrogenation catalyst to produce an unsaturated aliphatic primary amine, wherein 0.01 parts by weight to 1.0 part by weight of aromatic carboxylic acid amide is added based on 100 parts by weight of the unsaturated aliphatic nitrile, and a partial pressure ratio of ammonia to hydrogen is adjusted to 8/2 to 6/4. The present invention also relates to an unsaturated aliphatic primary amine, which is produced by the production method.
    Type: Grant
