Abstract
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.
