A pillar[5]arene-based crosslinked polymer material for selective adsorption of organic dyes was written by Zhang, Ge;Lou, Xin-Yue;Li, Meng-Hao;Yang, Ying-Wei. And the article was included in Dyes and Pigments in 2022.Safety of Trimesoylchloride This article mentions the following:
Industrial wastewater containing organic dyes poses severe threats to the global aquatic ecosystem. The exploration of low-cost and environmentally friendly adsorbents has become a major task for the fast and effective elimination of organic dye contaminants. The authors fabricate a new type of polymeric dye adsorbent (P1) by crosslinking bihydrazide-functionalized pillar[5]arene with trimesoyl chloride as linkers. Benefiting from the π-electron rich cavity of pillar[5]arene, P1 demonstrated outstanding potential in the selective adsorption and separation of small cationic dyes. Kinetic exptl. results prove that the adsorption behaviors for methylene blue (MB) and neutral red (NR) are accurately matched with the pseudo-second-order model and Freundlich isotherm model. The integral adsorption rate is determined by both external diffusion and intra-particle diffusion. The pillararene-based polymer adsorbent can be recycled 5 times with almost no loss of adsorption efficiency, holding great potential to function as an available material for wastewater regeneration and purification In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Safety 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. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Safety of Trimesoylchloride
