<p><P>PROBLEM TO BE SOLVED: To provide a method for producing a polyether monool and a polyether polyol having a high primary hydroxy group ratio in high yield with little byproducts and allowing easy post-treatment process. <P>SOLUTION: In this method, the polyether monool (B1) represented by general formula (3) is prepared by reacting a monohydric alcohol (A1) represented by general formula (1) with an alkylene halohydrin (D) represented by general formula (2) in the presence of an acid catalyst (C). The formulas are: R<SP>1</SP>O-(AO)<SB>m</SB>-H (1); X-R<SP>2</SP>-OH (2); and R<SP>1</SP>O-(AO)<SB>m</SB>-R<SP>2</SP>-OH (3). In the formulas, R<SP>1</SP>is a 2-22C hydrocarbon group, AO is a 2-4C oxyalkylene group, m is a number of 0-200, R<SP>2</SP>is a 2-4C alkylene group, and X is a halogen atom. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
