Abstract: The main impurities in aqueous solution of monoethanolamine used in various stages of gas treatment at the Omsk Oil Refinery Joint-Stock Company were identified by 1H and 13C NMR spectroscopy. A mechanism of their formation was proposed. A probable dependence of service characteristics of the absorbent on its composition was considered.
