Abstract:
A method for producing an alkoxylated compound by supplying an alkylene oxide to an active hydrogen-containing compound delivered to an agitating reaction vessel, characterized by a reaction solution in the process of an alkylene oxide addition reaction having highest viscosity of not less than 10 mPaÂ·s, the reaction solution being stirred by the rotation of a vane or vanes continuously disposed in the vertical direction in the agitating reaction vessel, and the numerical value C represented by the following formula (1):C=A/(h2âˆ’h1)â€ƒâ€ƒ(1) (wherein A denotes the length (m) of the vane or the vanes newly immersed by the supply of alkylene oxide, h1 denotes the height (m) of the liquid level before the supply of alkylene oxide, and h2 denotes the height (m) of the liquid level after the supply of alkylene oxide) being not less than 0.5.
