4-Amino-1-methylpiperidine (cas: 41838-46-4) belongs to piperidine derivatives. The piperidine ring can be found not only in more than half of the currently known structures of alkaloids, but also in many natural or synthetic compounds with interesting biological activities. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol.SDS of cas: 41838-46-4

CO2 absorption performance in advanced water-lean diamine solvents was written by Xu, Yanjie;Wang, Tao;Yang, Qi;Yu, Hai;Fang, Mengxiang;Puxty, Graeme. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2021.SDS of cas: 41838-46-4 This article mentions the following:

In an effort to reduce energy penalties, a range of advanced water-lean solutions blended from one of 8 diamines, an organic solvent diluent and water, were screened. The diamines N,N-dimethyl-1,3-propanediamine and N,N-dimethyl-1,2-ethanediamine with one primary and one tertiary amino group remain homogenous during CO2 uptake with the addition of cosolvents (1-methyl-2-pyrrolidinone or sulfolane) and are further investigated for absorption and desorption performance compared with their corresponding aqueous solutions Water-lean solutions with different water concentrations are tested to explain the impact of water content on the solution performance. Phys. properties such as d. and viscosity are also measured for a versatile evaluation. The results show that diamine water-lean solutions obtain low viscosity, preferable cyclic capacities and rapid absorption and desorption rates. ENH-5% H2O (mass ratio DMEDA: NMP: H2O = 3:6.5:0.5) shows the most competitive advantages with comparable viscosity (1.49 mPa鈥 at 313 K) to aqueous MEA-H2O and a 140% improvement in cyclic capacity. Four-fold higher desorption rate is gained ESH-5%H2O (mass ratio DMEDA: SFL: H2O = 3:6.5:0.5) compared with MEA-H2O. Considerable reduction in energy penalties is expected to be achieved in diamine water-lean solutions In addition, the equilibrium solubility of diamine water-lean solutions also shows potential for industrial application due to their sensitivity to CO2 partial pressure in contrast with aqueous solutions In the experiment, the researchers used many compounds, for example, 4-Amino-1-methylpiperidine (cas: 41838-46-4SDS of cas: 41838-46-4).
