| titleOfInvention | Method of polyester polyol excellent in mixing property with hydrocarbon blowing agent and flame retardancy |
| abstract | The present invention relates to a process for producing a polyester polyol having excellent mixing property with a hydrocarbon-based foaming agent which is an environmentally friendly foaming agent capable of replacing CFCs (trichloromonofluoromethane) and HCFCs (hydrochlorofluorocarbons) and flame retardancy. The present invention relates to a process for producing an aliphatic polyhydric alcohol represented by the following formula (1), which comprises reacting an aldehyde compound represented by the formula (2) and a first polyhydric alcohol represented by the formula (1) step; A second step of separating the aliphatic polyhydric alcohol from the mixture of the first step; As shown in Reaction Scheme 2, the catalyst is put into a reaction mixture in which an aliphatic polyhydric alcohol represented by Chemical Formula 3, a polyvalent carboxylic acid represented by Chemical Formula 4, and a second polyhydric alcohol represented by Chemical Formula 5 are mixed, And a third step of synthesizing a polyester polyol represented by the general formula (6) |
