On October 12, 2017, Narku-Tetteh, Jessica; Muchan, Pailin; Saiwan, Chintana; Supap, Teeradet; Idem, Raphael published an article.Synthetic Route of 2160-93-2 The title of the article was Selection of components for formulation of amine blends for post combustion CO2 capture based on the side chain structure of primary, secondary and tertiary amines. And the article contained the following:
Side chain structure and number of OH- groups in primary, secondary, and tertiary amines effect on CO2 absorption and desorption kinetics, equilibrium loads, heat duty, cyclic capacity, heat of absorption, and pKa were assessed and used to develop rational criteria to select components to formulate an optimum amine blend. Based on these criteria, amines which had a combination of high absorption and desorption parameters were selected. Their mixing ratios and concentrations were varied to obtain best overall performance. Results showed that in comparison with their straight-chain analogs, steric hindrance present in branched-chain alkanolamines resulted in much faster desorption rate, higher CO2 solubility and cyclic capacity, and much lower heat duty for solvent regeneration, but just a slight decrease in CO2 absorption rate. Developed criteria resulted in formulating an excellent bi-solvent aqueous amine blend (comprised of 2 M BEA + 2 M AMP), shown to have outstanding desorption characteristics/heat duty and very good absorption characteristics. Also, this work developed a non-trial-and-error procedure to determine heat of CO2 absorption based on Gibbs-Helmholtz equation. It showed the CO2 absorption rate and heat of CO2 absorption may not necessarily be proportional to the heat of absorption and heat duty, resp. Both these relations were shown to be strong functions of amine structure. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Synthetic Route of 2160-93-2
