<P>PROBLEM TO BE SOLVED: To provide a catalyst solution for producing polyalkylene glycol comprising a basic iminophosphazenium salt solution which can store the basic iminophosphazenium salt useful as an organic base for a long period of time and a process for producing polyalkylene glycol using the catalyst solution for producing polyalkylene glycol. <P>SOLUTION: The catalyst solution for producing polyalkylene glycol comprises a basic iminophosphazenium salt and a solvent containing at least one protonic organic solvent having a solubility parameter of not less than 10 (cal/cm<SP POS="POST">3</SP>)<SP POS="POST">1/2</SP>and the process for producing polyalkylene glycol uses the same. <P>COPYRIGHT: (C)2012,JPO&INPIT |
