Quantitatively relating the structural performance of polyamide layer with skin layer modified via in-situ precipitation was written by Zuo, Hao-Ran;Pang, Shu-Ya;Duan, Ming;Su, Wei;Shu, Hang;Xu, Xiang-Feng. And the article was included in Journal of Membrane Science in 2022.Application In Synthesis of Trimesoylchloride This article mentions the following:
How the structure of skin layer determines the structure of incipient film and final membrane formed during interfacial polymerization is decisive for polyamide composite membranes but difficult to monitor. This work introduced a methodol. to predict an estimated initial molar ratio between monomers (畏) via introducing pore diameter (dp), porosity (蔚Skin), tortuosity (蟿Skin), and thickness (lSkin) of skin layer to Fick’s diffusion law to correct flux of monomers. The structure of skin layer was regulated via in-situ preparation of sacrificial precipitation With characterized parameters of dp = 25.91 nm, 蔚Skin = 8.32%, 蟿Skin = 7.41, and lSkin = 260 nm, 畏 was 4.25. The resultant forward osmosis membrane exhibited flux of 58.83 卤 3.58 L/(m2路h) and reverse salt flux of 10.68 卤 2.38 g/(m2路h) under AL-DS mode with 1.0 mol/L NaCl and DI as draw and feed solution, resp., which had broken historical upper boundary. The proposed methodol. can make quant. prediction for the structural performance of polyamide composite membranes. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Application In Synthesis of Trimesoylchloride).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Application In Synthesis of Trimesoylchloride
