Zusammenfassung:	To provide a basic iminophosphazenium salt-containing composition that enables a basic iminophosphazenium salt, which is expected to be useful as an organic base, to be stored and transported stably for a long time even at high temperatures (50°C or higher), and a method for producing polyalkylene glycol using the same.SOLUTION: A solution in which a basic iminophosphazenium salt is dissolved in a solvent containing water and a protic organic solvent with a solubility parameter of 10 (cal/cm3)1/2 or more has excellent storage stability at high temperatures and is useful as a catalytic solution for the production of polyalkylene glycol.SELECTED DRAWING: None 【課題】有機塩基として有用性が期待される塩基性イミノホスファゼニウム塩を高温下（５０度以上）でも長期間安定に保存、輸送することが可能となる塩基性イミノホスファゼニウム塩含有組成物およびそれを用いてなるポリアルキレングリコールの製造方法を提供する。【解決手段】塩基性イミノホスファゼニウム塩を、水及び溶解度パラメータが１０（ｃａｌ／ｃｍ３）１／２以上であるプロトン性有機溶媒を含有する溶媒に溶解した溶液が、高温下での保存安定性とポリアルキレングリコール製造用触媒溶液として優れたものとなる。【選択図】なし
