Title:
ニトリル類の連続接触還元による一級アミンの製造方法
Document Type and Number:
Japanese Patent JP6748634
Kind Code:
B2
Abstract:
[Problem] The present invention addresses the problem of providing a new method that is for manufacturing a primary amine through catalytic hydrogen reduction of a nitrile and that enables obtaining of a primary amine with high selectivity and fine yield even at low hydrogen pressure. [Solution] A method for producing a primary amine, characterized by continuous catalytic reduction of a nitrile by feeding, together with hydrogen such that the hydrogen pressure is not higher than 1 MPa, a solution containing the nitrile coexisting with an acid, into a flow synthesis system having a flow path through which a solution is fed, and having a column located within the flow path and loaded with a fixed platinum group metal catalyst.
