Method for producing polyether polyol and method for producing polyurethane foam |
| abstract |
It is an object of the present invention to provide a method for producing a polyether polyol having a smaller content of aldehyde contained in a polyether polyol and having a simpler process, and a method for producing a polyurethane foam having a smaller amount of aldehyde to be volatilized. The method for producing a polyether polyol (F) of the present invention comprises 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 in the presence of an acid catalyst ( It has the process (1) of contacting B) and obtaining the crude polyether polyol composition (D2) whose pH exceeds 5.0, and the process (2) which removes the volatile matter containing an aldehyde (C) after a process (1). |
