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. 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.
本发明的目的是提供高纯度的γ-丁内酯(GBL),能够防止在使用时发生目的之外的反应,这种反应是由于γ-丁内酯的高酸度引起的。本发明涉及一种含有γ-丁内酯和含氮化合物的γ-丁内酯组合物,其中γ-丁内酯的含量为 99.0%(质量分数)或以上,含氮化合物的总含量为 0.1 ppm(质量分数)至 1 000 ppm(质量分数)(转换为氮原子)。
