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 Chlorine-Resistant Epoxide-Based Membranes For Sustainable Water Desalination, published in 2021-09-14, which mentions a compound: 111-18-2, mainly applied to chlorine resistant polyepoxyether membrane water desalination, Safety of N1,N1,N6,N6-Tetramethylhexane-1,6-diamine.
The hypersensitivity of state-of-the-art polyamide-based membranes to chlorine is a major source of premature membrane failure and module replacement in water desalination plants. This problem can currently only be solved by implementing pre and post-treatment processes involving addnl. chem. use and energy input, thus increasing environmental, capital, and operational costs. Herein, we report a chlorine, acid and base resistant desalination membrane comprising a cross-linked epoxide-based polymer-selective layer with permanent pos. charges. These novel membranes exhibit high mono- and divalent salt rejection (81% NaCl, 87% CaCl2, 89% MgCl2) and a water permeance of 2 L m-2 h-1 bar-1, i.e., desalination performance comparable to that of com. available nanofiltration membranes. Unlike conventional polyamide-based membranes, this new generation of epoxide-based membranes takes advantage of the intrinsic chem. stability of ether bonds while achieving the polymer and charge needed for desalination. In doing so, the stability of these membranes opens new horizons for sustainable water purification and many other separations in harsh media in a variety of applications (e.g., solvent recovery, gas separations, redox flow batteries).
As far as I know, this compound(111-18-2)Safety of N1,N1,N6,N6-Tetramethylhexane-1,6-diamine can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
