| titleOfInvention | Method for the production of a polyhydric alcohol from a urethane containing polymer |
| abstract | A method is described for the production of a polyhydric alcohol from a urethane containing polymer. The method first provides a reaction mixture comprising said polymer, a reactive solvent, which comprises a polyol; and a catalyst, comprising catalyst particles. Said polymer is depolymerized in said reaction mixture by reacting with said polyol to produce said polyhydric alcohol. A further step allows said reaction mixture containing said polyhydric alcohol product to separate into a product phase containing said polyhydric alcohol and another phase mainly containing said polyol and said catalyst. The catalyst is recovered from said another phase, while said polyhydric alcohol product is recovered from said product phase. The catalyst is a catalyst complex comprising the catalyst particles and a catalyst entity covalently bonded to the catalyst particles via a linking group, wherein the catalyst entity comprises a cationic moiety having positive charge and a negative moiety having negative charge. |
