摘要:
Amine compositions comprising sterically hindered amines and associated methods are provided. In some embodiments, amine compositions of the present disclosure may be useful for selective removal of H 2 S from an acidic gas stream.
摘要:
The present disclosure provides a scrubbing composition containing an aqueous solution of 2-(3-aminopropoxy)ethan-1-ol. The scrubbing composition is especially suited for use in removing acid gases, such as carbon dioxide and hydrogen sulfide, from gas streams.
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 in the foam that is produced.
