超臨界二酸化炭素中における有機ニトリル化合物の水素化物の製造方法

Document Type and Number:

Japanese Patent JP5565799

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a method for producing a hydride of an organic nitrile compound in supercritical carbon dioxide.SOLUTION: A hydride of an organic nitrile compound is produced by using supercritical carbon dioxide (scCO) during hydrogenation of an organic nitrile compound and using a Pd/MCM-41 catalyst or Rh/AlOcatalyst without using an additive, for example, hydrogenating benzonitrile into benzylamine in high selectivity (90.9%) and hydrogenating adiponitrile into 6-aminocapronitrile in a high conversion and in high selectivity (100% selectivity). Selectivity depends on the COpressure, for example, a primary amine is formed in a low pressure range by an action of COas a protective agent and yield of primary amine and solubility of imine intermediate in COare increased to improve selectivity of dibenzylamine.
