Highly heat-resistant NF membrane modified by quinoxaline diamines for Li+ extraction from the brine was written by Xie, Huan-Yin;Tang, Run-Hua;Chen, Gui-E.;Xu, Zhen-Liang;Mao, Hai-Fang. And the article was included in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) in 2022.SDS of cas: 4422-95-1 This article mentions the following:
The functional layers with excellent heat-resistance nanofiltration (HRN) property were designed by fixing thermal stabilized quinoxaline diamines (QHDA) on poly (m-phenyleneisophthalamide) (PMIA) substrate through interfacial polymerization QHDA was used as aqueous monomer while cinnamoyl chloride (CNC), isophthaloyl chloride (IPC) and trimesoyl chloride (TMC) were served as organic monomers to realize the immobilization of thermally stable N heterocycles. The exptl. results stated clearly that the compact package reaction of QHDA with TMC lead a raise of thermal stability and salts rejection at high temperature stream. With the optimal TMC and 0.5 weight% QHDA, the as-developed membrane achieved the excellent NF performance and thermal stability. The rejection of MgSO4 reached to 94.6% at 30°C and hardly decrease at 90°C. The reduction in rejection was satisfactory at high temperatures The functional layer still showed highly stability after 10 h long-term operation at 90°C with only 2.8% reduction in MgSO4 rejection. Besides, the excellent Mg2+ and poor Li+ rejection made this membrane have huge potential in the application of extracting Li+ from brine. The separation factor of Mg2+-Li+ at high temperature was satisfactory. Over all, this study offered a prospect technol. to exploit heat-resistant membranes for extraction lithium at high temperature In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1SDS of cas: 4422-95-1).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.SDS of cas: 4422-95-1
