| titleOfInvention | Method for purifying tetrahydrofuran |
| abstract | Provided is a method for producing tetrahydrofuran capable of efficiently and continuously recovering high-purity tetrahydrofuran while suppressing catalyst deterioration when producing high-purity tetrahydrofuran from crude tetrahydrofuran. At least one compound selected from the group consisting of an aldehyde having 1 to 6 carbon atoms, a ketone having 1 to 6 carbon atoms, and an olefin having 1 to 6 carbon atoms, and a concentration in terms of nitrogen atom, are used for crude tetrahydrofuran. And a step of bringing the raw crude tetrahydrofuran into contact with a solid catalyst containing, as an active ingredient, a metal belonging to Groups 8 to 11 of the periodic table (a) containing 0.001 to 3 ppm by weight of a nitrogen atom-containing compound (a) ), Contacting the crude tetrahydrofuran treated in step (a) with a solid catalyst containing a metal element different from the metal in step (a) as an active component, and then separating and recovering high-purity tetrahydrofuran A method for producing tetrahydrofuran, comprising (b). [Selection figure] None |
