Method for producing polyether polyol and method for producing polyurethane foam |
| abstract |
It aims at providing the manufacturing method of the polyether polyol which has little content of the aldehyde contained in a polyether polyol, and has a simpler process, and the manufacturing method of a polyurethane foam with little amount of aldehyde to volatilize. In the method for producing the polyether polyol (F) of the present invention, a crude polyether polyol composition (D1) containing a polyether polyol (A) obtained by ring-opening polymerization of an alkylene oxide to an active hydrogen compound is used in the presence of water. A step (1) of obtaining a crude polyether polyol composition (D2) having a pH of more than 5.0 by contacting with an acid catalyst (B) under the above, and a volatile component containing an aldehyde (C) after the step (1) (2) which removes. |
