Method for cleaving polyurethane products |
| abstract |
The invention relates to a method for cleaving polyurethane products, having the steps of (A) providing a polyurethane product which is based on isocyanate components and a polyol component; (B) reacting the polyurethane product with a monofunctional araliphatic alcohol in the presence of an alcoholysis catalyst, thereby obtaining a product mixture containing a liquid polyol phase and a solid carbamate of an isocyanate of the isocyanate component and the monofunctional araliphatic alcohol; and (C) separating the carbamate from the product mixture, thereby leaving the liquid polyol phase. |
