Removal of volatile radioiodine from air and wastewater streams using porous materials is imperative to curb its long-term adverse effects on the environment. Herein, we report the development of a hydrogel system (PEIG) using polyethylenimine and glutaraldehyde followed by production of xerogel (PEIXG). PEIXG effectively captured iodine in its vapor form with an excellent adsorption capacity of 2.9 g/g. Addnl., PEIXG efficaciously removed dissolved iodine from water and nonpolar solvent. Moreover, the reversible nature of the uptake enabled good recyclability and utilization of I2-PEIXG as a catalyst for the synthesis of an important class of functional heterocycle, 2-aminobenzothiazoles. In the experiment, the researchers used many compounds, for example, N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6Application of 1843-21-6).
N-Phenylbenzo[d]thiazol-2-amine (cas: 1843-21-6) belongs to thiazole derivatives. Thiazole rings are planar and aromatic. Thiazoles are characterized by larger pi-electron delocalization than the corresponding oxazoles and have therefore greater aromaticity. Thiazole sulfonation occurs only under forcing conditions: the action of oleum at 250 °C for 3 hours in the presence of mercury(II) sulfate leads to 65% formation of 5-thiazole sulfonic acid.Application of 1843-21-6
