摘要： In an embodiment, an amine-oxidation inhibitor, such as a free radical scavenger and/or antioxidant, is added to an oxidation-sensitive amine, such as an amine catalyst, to inhibit oxidation of the amine. The inhibitor-treated amine may then be used in an application such as a polyurethane application to reduce the emission of undesired oxidation products from the polyurethane.

摘要： The present disclosure provides a method for reducing the aldehyde content in an amine catalyst by treating the amine catalyst with a treating agent selected from a cyclic urea substituted with at least one isocyanate reactive group, a free radical scavenger and a mixture thereof. The treated amine catalyst may then be used in the production of polyurethane materials which exhibit reduced aldehyde emissions.

摘要： The present disclosure relates to pyrrolidine-based catalysts for use in a polyurethane formulation. The polyurethane formulation includes the pyrrolidine-based catalyst, a compound containing an isocyanate functional group, an active hydrogen-containing compound. The use of such catalysts produces high quality polyurethane foam while reducing environmental concerns that can arise during the production of polyurethane foam as well as in the foam that is produced.
