On July 31, 2017, Perinu, Cristina; Bernhardsen, Ida M.; Svendsen, Hallvard F.; Jens, Klaus-J. published an article.Product Details of 2160-93-2 The title of the article was CO2 Capture by Aqueous 3-(Methylamino)propylamine in Blend with Tertiary Amines: An NMR Analysis. And the article contained the following:
Aqueous 3-(Methylamino)propylamine (MAPA) in blend with 2-(Diethylamino)ethanol (DEEA) and other tertiary amines, which mainly differ from DEEA in the number of hydroxyl functions (-OH) and/or in the length and structure of their alkyl chain, are investigated. After absorption of carbon dioxide (CO2) at 40°C, quant. 13C NMR experiments are performed to calculate the concentration of the species in each blend at equilibrium, together with qual. NMR experiments for signal assignment. Speciation and absorption capacity data are discussed in terms of chem. structure and basicity of the tertiary amines. In general, it is observed that, at increasing pKa of the tertiary amines (decreasing number of -OH on the structure), there is a decrease of MAPA and primary and secondary MAPA carbamates, and an increase of MAPA dicarbamate, (bi)carbonate and of the absorption capacity. Within the mols. with the same number of -OH but differently branched, some exceptions are found. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Product Details of 2160-93-2
