Abstract
PURPOSE: To prepare a polyether compound having low degree of unsaturation, in high efficiency, suppressing the production of by-product, by adding an alkylene oxide to a compound having active hydrogen using an alkali metal compound and a phasetransfer catalyst as reaction catalysts.
CONSTITUTION: The objective compound can be prepared by the addition reaction of (A) a compound having active hydrogen (e.g. polyhydric alcohol, amine, etc.) with (B) an alkylene oxide (pref. propylene oxide having an OH value of 15W200 or its combination with ethylene oxide) in the presence of reaction catalysts comporising (C) an alkali metal compound and (D) a phase-transfer catalyst (pref. a quarternary ammonium salt) e.g. at 80W180°C. The amount of the C component is 1W30wt% of the A component, and that of D is pref. 10W100mol% of the C component.
