(Polyurethane) A method for producing a hydroxy functional compound from polyurea waste |
| abstract |
The present invention is directed to decomposing polyurethane and / or polyurethane polyurea plastic wastes into alcohols, which continue to react the dihydric alcohol decomposition products to lower the content of low levels of steric hindrance aromatic amines therefrom. A method for preparing hydroxyfunctional compounds suitable for use in polyisocyanate polyaddition processes. In this process, the polyurethane and / or polyurethane polyurea waste is first treated with low molecular weight diols or polyols at temperatures of about 160-260 ° C. Subsequently, the resultant alcohol alcohol decomposition product is further heated in a temperature range of about 50-180 ° C. or lower than the temperature used in the first step, or dialkyl dicarbonate and / or 1,3-dica React with the ribonyl compound. |
