PROBLEM TO BE SOLVED: To provide a method for producing tetrahydrofuran by which there are advantages that the yield and amount of the produced tetrahydrofuran based on the weight of a catalyst (STY) are improved, a reaction can be carried out within a wide range of low temperatures to high temperatures without requiring the use of a high-class material in a reactor due to no use of sulfuric acid, etc., and the reaction further completely proceeds even when the amount of water required for the reaction is reduced and a load on water separation after the reaction is reduced or the like. SOLUTION: A hydrous metal oxide catalyst is used as a catalyst in a method for subjecting a fatty acid ester of 1,4-butanediol to a catalytic reaction with water and producing tetrahydrofuran. The metal of the hydrous metal oxide catalyst is preferably at least one kind of metal selected from groups 4, 5 and 14 elements of the periodic table and the metal of the hydrous metal oxide catalyst is more preferably niobium or tantalum. |
