INHIBITION OF AMINE OXIDATION

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.

主权项

1. A method of forming an inhibitor-treated amine comprising:
combining an oxidation-sensitive amine selected from one or more of an amine catalyst, a polyetheramine, an ethyleneamine, an alkoxylated amine, and a surfactant amine with an amine-oxidation inhibitor to form an inhibitor-treated amine.
