Abstract
A tertiary amine, such as a tertiary amine catalyst that is useful in the production of polyurethanes, may undergo decomposition, which may result in the production of undesirable products. These tertiary amines, however, may be treated with a primary amine containing material to reduce the presence of the undesirable products to an acceptable level. Thus, a foam made from a treated tertiary amine will also have a reduction in the presence of the same undesirable products.
