Latest Patents

Pohl’s listed patent, “Method for Recovering Raw Materials from Polyurethane Products,” describes a process for recovering polyols and, optionally, an amine corresponding to an isocyanate used in the polyurethane.

The method reacts a polyurethane product with an alcohol in the presence of a catalyst, producing a mixture that can contain alcohol, polyols, carbamates, and water. The mixture is then combined with a compatible organic solvent and washed with an aqueous fluid. During washing, some carbamates are hydrogenated, releasing amines and alcohol. Phase separation produces a solvent phase containing the organic solvent and polyols, which is processed to obtain the polyols. The aqueous phase can also be processed to recover the corresponding amine.
