Abstract: PROBLEM TO BE SOLVED: To provide a pyrrolidone composition containing few kinds of impurities deteriorating the quality such as hue of the composition. SOLUTION: The pyrrolidone composition is produced by reacting a compound selected from ammonia, primary amine, secondary amine and tertiary amine or their mixture with a γ-butyrolactone raw material satisfying a specific condition such as a γ-butyrolactone mixture free from impurities having UV absorption higher than the UV spectrum absorption of the γ-butyrolactone.

Abstract: PROBLEM TO BE SOLVED: To directly and efficiently produce a corresponding oxide (ester or acid anhydride) from an ether in high conversion and selectivity by bringing an ether into contact with oxygen in the presence of an oxidation catalyst constituted with a specific imide compound. SOLUTION: In the presence of an oxidation catalyst comprising an imide of the formula (R and R are each H, a halogen, an alkyl, an aryl, etc., R and R may link to each other to form a double bond or a ring; X is oxygen or hydroxyl; n is 1-3) or a mixture thereof with a cocatalyst (for example, an oxide, an organic acid salt, an inorganic acid salt, a halide, a complex and heteropolyacid of transition metal compound), an acyclic ether or a nonaromatic cyclic ether is brought into contact with oxygen in an organic solvent inactive to the reaction, at 0-300 deg.C, preferably 30-250 deg.C for 30 minutes to 48 hours, preferably for 2-24 hours to oxide the ether to the objective compound.
