The piperazines are a broad class of chemical compounds, many with important pharmacological properties, which contain a core piperazine functional group. 103-76-4, formula is C6H14N2O, Name is N-(2-Hydroxyethyl)piperazine. A form in which piperazine is commonly available industrially is as the hexahydrate, C4H10N2. 6H2O, which melts at 44 °C and boils at 125–130 °C. Application of C6H14N2O.
Zhou, Zhiwei;Lin, Yuqing;Jin, Yan;Guan, Kecheng;Matsuyama, Hideto;Yu, Jianguo research published 《 Removal of heat-stable salts from lean amine solution using bipolar membrane electrodialysis》, the research content is summarized as follows. Traditional resin exchange processes for the removal of heat-stable salt (HSS) from lean amine solutions have limited efficiency, and require large amount of alkali for regeneration, causing a serious neg. impact on the sustainable environmental development. In this study, a new bipolar membrane electrodialysis (BMED) process was proposed to replace the original resin-based method for the removal of HSS from practical lean amine liquids (from a natural gas factory of PetroChina Company). The exptl. conditions of c.d., volumetric ratio, HSS concentration, and etc., were systematically investigated. It was found that a high HSS removal efficiency of up to 95.7% with an extremely low loss rate of the organic amine of down to 1.39% can be obtained, under the optimal c.d. of 60 mA/cm2. A continuous operation verified the long-term stability of BMED for a high-efficiency HSS removal rate of up to 80.3% after a 600-h duration. From the findings in this study, we develop a conceptual exploration describing the BMED process for the separation of HSS from practical desulfurization wastewater, beyond the lean amine liquids, offering a guidance for their potential industrial applications.
Application of C6H14N2O, 1-(2-Hydroxyethyl)piperazine is a useful research compound. Its molecular formula is C6H14N2O and its molecular weight is 130.19 g/mol. The purity is usually 95%.
1-(2-Hydroxyethyl)piperazine is a chemical solvent that is used for the absorption of amines and other compounds. It has been shown to have a high affinity for acidic substances, which may be due to its ability to form hydrogen bonds with them. 1-(2-Hydroxyethyl)piperazine is also used in sample preparation for the analysis of amines and other compounds in fruit extracts. The solubility of 1-(2-Hydroxyethyl)piperazine depends on the experimental conditions, including pH, temperature, and pressure. FT-IR spectroscopy has been used to measure the vibrational modes of 1-(2-Hydroxyethyl)piperazine molecules. The IR spectrum revealed that this compound contains a hydroxyl group and two fatty acid chains with one or more hydroxyl groups at their terminal end. The nmr spectrum showed that 1-(2-Hydroxyethyl)piperazine contains an NH proton as well as, 103-76-4.
