The present invention provides a method of producing a nitrile from a primary amide, characterized in that the primary amide is subjected to a dehydration reaction in a supercritical fluid in the presence of an acid catalyst. The present invention achieves the object of reducing the corrosion of a reactor and the thermal decomposition of raw materials, as well as provides the effect of improving the reaction rate and nitrile selectivity.

The present invention is a method of producing -caprolactam through adipamide as an intermediate, and characteristically includes a lactamization step of reacting adipamide, formed from a material compound, with hydrogen and ammonia in the presence of a catalyst containing: a metal oxide mainly containing an oxide(s) of one or more metallic elements selected from the group consisting of metallic elements of group 5 and groups 7 to 14 in the 4th to 6th periods of the periodic table; and a metal and/or a metal compound having a hydrogenation ability. The method can increase the selectivity of -caprolactam.
