Method for production of alkoxylated compound |
| abstract |
When the reaction solution formed during the addition of an alkylene oxide to an active hydrogen-containing compound has viscosity of not less than 10 mPa·s, this invention provides a method for stirring the reaction solution by the rotation of a vane or vanes continuously disposed in the vertical direction within an agitating reaction vessel in such a manner that the numerical value C represented by the following formula (1) : C = A / h 2 - h 1 n(wherein A denotes the length (m) of the vane or the vanes newly immersed by the supply of alkylene oxide, h 1 denotes the height (m) of the liquid level before the supply of alkylene oxide, and h 2 denotes the height (m) of the liquid level after the supply of alkylene oxide) may be not less than 0.5. By employing the method of this invention, it is made possible to effect addition of an alkylene oxide to the active hydrogen-containing compound with high efficiency. Further, the use of this method allows repression of the content of a by-product which causes the degradation of the characteristic properties of the alkoxylated compound. |
