Abstract: The present disclosure provides a method for reducing the aldehyde content in an amine catalyst by treating the amine catalyst with an organic acid. The organic acid-treated amine catalyst may then be used in the production of polyurethane materials which exhibit reduced aldehyde emissions.

Abstract: 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.
