Competitive Formation of N -Diazeniumdiolates and N -Nitrosamines via Anaerobic Reactions of Polyamines with Nitric Oxide [PDF]

, 2009
Reactions of amines with nitric oxide (NO) at high pressures form diverse NO donor species, highly dependent on the precursor structure. While monoamine precursors favor the formation of N-diazeniumdiolates in high yield, polyamines exhibit competitive ...

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.
