Highly Efficient SO2 Absorption and Its Subsequent Utilization by Weak Base/Polyethylene Glycol Binary System was written by Yang, Zhen-Zhen;He, Liang-Nian;Zhao, Ya-Nan;Yu, Bing. And the article was included in Environmental Science & Technology in 2013.Formula: C11H20N2 This article mentions the following:
A binary system consisting of polyethylene glycol (PEG, proton donor)/PEG-functionalized base with suitable basicity was developed for efficient gas desulfurization (GDS) and is regarded as an alternative approach to circumvent the energy penalty problem in the GDS process. High capacity for SO2 capture (â?.88 mol SO2/mol base) was achieved, even under low SO2 partial pressure. SO2 desorption operates smoothly under mild conditions (N2, 25°); no significant drop in SO2 absorption was observed after 5 successive absorption/desorption cycles. SO2 absorbed by PEG150MeIm/PEG150, considered the activated form of SO2, can be directly transformed into value-added chems. under mild conditions, eliminating the energy penalty for SO2 desorption and simultaneously recycling the absorbents. Thus, this SO2 capture and utilization process offers an alternative way for GDS and potentially enables SO2 conversion from flue gas to useful chems. as a value-added process. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Formula: C11H20N2).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Formula: C11H20N2
