| titleOfInvention | Method and apparatus for producing polyester polyol, polyester polyol and polyurethane foam |
| abstract | To provide a method for producing polyester polyol that can provide a simple process to produce extensively improved production efficiencies and also produce the polyester polyol of stable in quality, an apparatus for producing the polyester polyol produced by the method, a polyester polyol produced by the method, and a polyurethane foam obtained by use of the polyester polyol produced by the method, polyethylene terephthalate and raw polyol are allowed to react in a reaction vessel to produce polyester polyol and also ethylene glycol which is a by-product of the reaction is distilled off and the distillate is modified in a modifying vessel so that it can have a predetermined hydroxyl value and then is fed to the reaction vessel again as the raw glycol, to thereby produce the polyester polyol. |
