摘要：
Provided are a divalent phosphazenium salt which is neutral and is excellent in thermal stability and aldehyde scavenging ability, and a method for producing the same. Also provided are a polyalkylene oxide composition having a volatile aldehyde amount reduced, having generation of odor and turbidity suppressed and being excellent in urethanization reactivity, and a method for producing such a polyalkylene oxide composition, as well as a polyurethane-forming composition containing the polyalkylene oxide composition. A divalent phosphazenium salt having a specific structure. Also, a polyalkylene oxide composition comprising a divalent phosphazenium salt having a specific structure and a polyalkylene oxide, a method for producing the same, and a polyurethane-forming composition containing the same.
