PURPOSE: An insoluble heteropoly acid-heterocycle catalyst, a producing method thereof, and a producing method of nitrile compound using thereof are provided to economically produce the heteropoly acid-heterocycle catalyst compare to a conventional precious metal catalyst. CONSTITUTION: An insoluble heteropoly acid-heterocycle catalyst contains heteropoly acid and a heterocycle compound combined by ion exchanging. The heteropoly acid is inorganic condensation acid including the following: a coordinate element selected from the group consisting of vanadium, molybdenum, niobium, iron, and tungsten; and a central element selected from the group consisting of phosphorus, silicon, germanium, arsenic, boron, and cobalt. |
