In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Alkaline enrichment via electrodialysis with alkaline stable side-chain-type polysulfone-based anion exchange membranes, published in 2021-11-15, which mentions a compound: 111-18-2, mainly applied to quaternized chloromethylated polysulfone electrodialysis anion exchange membrane alk enrichment, Safety of N1,N1,N6,N6-Tetramethylhexane-1,6-diamine.
To meet the need of efficient resource utilization, developing stable and efficient anion exchange membranes (AEMs) for alk. enrichment application is of significance. In this work, we designed four polysulfone-based side-chain-type AEMs with several cations and different length of spacers per chain, to explore the structure-property relationship and obtained AEMs with high performance for alk. enrichment via electrodialysis (ED). Our investigation demonstrates that, the optimized AEM (CM-TQ6Q6Q-1, 1.38 mmol·g-1) exhibits low swelling ratio of 8.9%, low area resistance of 2.48 Ω·cm2, acceptable OH- conductivity of 13.7 mS·cm-1. In addition, this AEM also shows relatively good alk. stability with the IEC retention of 96.7% relative to the original IEC, suggesting the potential application of alk. enrichment via electrodialysis (ED). After 5-times NaOH enrichment tests in ED, CM-TQ6Q6Q-1 AEM shows an efficient ED performance with alk. concentration times of ∼1.8 (current efficiency: ∼90.0%; energy consumption: 8.47 kWh·kg-1), and maintains 96.4% of its original IEC, which are even comparable to those from com. AEM (Neosepta AHA). The results demonstrate that the as-prepared AEM shows the promising potential ED application for alkali enrichment from the alk. waste water.
I hope my short article helps more people learn about this compound(N1,N1,N6,N6-Tetramethylhexane-1,6-diamine)Safety of N1,N1,N6,N6-Tetramethylhexane-1,6-diamine. Apart from the compound(111-18-2), you can read my other articles to know other related compounds.
