An object of the present invention is to provide high-purity gamma-butyrolactone (GBL) capable of preventing occurrence of reaction other than the object at the time of use, which reaction is caused due to a high acidity of GBL, and the present invention relates to a gamma-butyrolactone composition containing gamma-butyrolactone and a nitrogen-containing compound, wherein a content of the gamma-butyrolactone is 99.0% by mass or more, and a total content of the nitrogen-containing compound is 0.1 ppm by mass to 1,000 ppm by mass as converted to a nitrogen atom.
A gamma-butyrolactone composition, comprising:
A method for producing a gamma-butyrolactone composition containing gamma-butyrolactone and a nitrogen-containing compound, in which a content of the gamma-butyrolactone is 99.0% by mass or more, and a total content of the nitrogen-containing compound is 0.1 ppm by mass to 1,000 ppm by mass as converted to a nitrogen atom,
