HPLC of Formula: 111-18-2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine, is researched, Molecular C10H24N2, CAS is 111-18-2, about Tertiary Amine-Ethylene Glycol Based Tandem CO2 Capture and Hydrogenation to Methanol: Direct Utilization of Post-Combustion CO2. Author is Sen, Raktim; Koch, Christopher J.; Goeppert, Alain; Prakash, G. K. Surya.
Carbon dioxide capture using tertiary amines in ethylene glycol solvent was performed under ambient conditions. Subsequently, the CO2 captured as alkyl carbonate salts was successfully hydrogenated to methanol, in the presence of H2 gas and Ru-Macho-BH catalyst. A comprehensive series of tertiary amines were selected for the integrated capture and conversion process. While most of these amines were effective for CO2 capture, tetramethylethylenediamine (TMEDA) and tetramethylbutanediamine (TMBDA) provided the best CH3OH yields. Deactivation of the base due to side reactions was significantly minimized and substantial base regeneration was observed The proposed system was also highly efficient for CO2 capture from a gas mixture containing 10% CO2, as found in flue gases, followed by tandem conversion to CH3OH. We postulate that such high boiling tertiary amine-glycol systems as dual capture and hydrogenation solvents are promising for the realization of a sustainable and carbon-neutral methanol economy in a scalable process.
