PHOSPHAZENIUM SALT, ITS PRODUCTION AND PRODUCTION OF POLYALKYLENE OXIDE

摘要

PROBLEM TO BE SOLVED: To produce a new phosphasenium salt useful as an active species, etc., for organic reactions and further as a polymerizing catalyst, etc., for alkylene oxides by reacting a salt of a phosphazenium cation with an inorganic anion with an alkali metallic salt of an active hydrogen compound. SOLUTION: This new phosphazenium salt of an active hydrogen compound is represented by formula I [(n) is an integer of 1-8 and denotes the number of phosphazenium cations; Z is an anion of an (n)-valent active hydrogen compound in the form derived by eliminating (n)×protons from the active hydrogen compound having the maximum 8 active hydrogens on the oxygen or nitrogen atom ; (a) to (d) are each an integer of <=3 or 0; all the (a) to (d) are not simultaneously 0; Rs are each a 1-10C hydrocarbon and two Rs on the same nitrogen atom may mutually be bonded to form a ring structure] and is useful as a reactive active species, etc., for organic reactions. The salt is produced by reacting a salt represented by formula II ](m) is an integer of 1-3 and denotes the number of phosphazenium cations; X is an (m)-valent inorganic anion] with a salt represented by the formula, M<+> n Z (M is an alkali metal).
