| titleOfInvention | Method for producing polyoxyalkylene monool or polyol |
| abstract | [PROBLEMS] To achieve addition polymerization even when the amount of catalyst used is small, yield is high, amount of side reaction products is small, amount of waste residue can be reduced, production efficiency is high, and polyoxyalkylene having a high terminal primary hydroxyl group ratio A process for producing monools or polyols is provided. An alkylene oxide is added to an active hydrogen group-containing compound (A) in the presence of at least one compound (E) selected from the group consisting of titanium alkoxide, zirconium alkoxide and vanadium alkoxide and a specific Lewis acid (C). A method for producing a polyoxyalkylene monool or polyol by addition polymerization of (B), wherein the active hydrogen group-containing compound (A) has a molar ratio of active hydrogen to the compound (E) {(mole number of active hydrogen of A ) / (Number of moles of E)} is 2,000 to 50,000, and the mole ratio of the compound (E) to the Lewis acid (C) {(number of moles of E) / (number of moles of C)} is The manufacturing method of the polyoxyalkylene monool or polyol which is 0.6-1.2. [Selection figure] None |
