Latest Patent Applications

Hinrichs-Tontrup has been involved in significant research, leading to the following latest patent applications:

1. **Depolymerization of Polyurethanes with Organic Amine Bases** - This hydrolyzing process enhances the depolymerization of polyurethanes by contacting the material with water in the presence of an organic amine base and a phase transfer catalyst. The mild reaction conditions and low salt concentration in the reaction mixture allow for increased yields of polyether polyol and organic polyamines.

2. **Depolymerization of Polyurethanes with Organic Amine Bases** - This method focuses on the depolymerization of polyurethanes produced by reacting an active hydrogen-containing polyether and an organic polyisocyanate. The process hydrolyzes the polyurethane under mild conditions and low salt concentration, allowing for the recovery of polyether polyols and polyamines in high yields. The quality of the recovered active hydrogen-containing polyether polyols is excellent.
