Abstract: front page image
(EN)The present invention addresses the issue of providing a highly pure gamma-butylolactone (GBL) that is capable of preventing the occurrence of unintended reactions during use, caused by high GBL acidity. This gamma-butylolactone composition contains gamma-butylolactone and a nitrogen-containing compound and is characterized by the gamma-butylolactone content being at least 99.0% by mass and the total nitrogen-containing compound content, in terms of nitrogen atoms, being 0.1-1,000 ppm by mass.
(FR)La présente invention vise à fournir une gamma-butylolactone (GBL) très pure qui est apte à empêcher l'apparition de réactions involontaires en cours d'utilisation, provoquées par une acidité de élevée de la GBL. Cette composition de gamma-butylolactone contient de la gamma-butylolactone et un composé contenant de l'azote et est caractérisée par la teneur en gamma-butylolactone qui est d'au moins 99,0 % en masse et la teneur totale en composé contenant de l'azote, en termes d'atomes d'azote, qui est de 0,1 à 1 000 ppm en masse.
(JA) 本発明はガンマブチロラクトン(GBL)の酸性度が高いことに起因した使用時における目的外の反応の生起を防止できる、高純度のGBLを提供することを課題とする。本発明はガンマブチロラクトン及び含窒素化合物を含有するガンマブチロラクトン組成物であって、前記ガンマブチロラクトンの含有量が99.0質量%以上であり、前記含窒素化合物の合計含有量が窒素原子換算で0.1質量ppm~1000質量ppmであることを特徴とするガンマブチロラクトン組成物に関する。
