In this research, a nano-inorganic composite of CuO/NiO is prepared by co-precipitation method as an efficient recyclable nanocatalyst for the regioselective synthesis of 1,4-disubstituted-1,2,3-triazoles in water. The catalyst was characterized by several techniques such as the field emission SEM (FESEM), energy dispersive spectroscopy (EDS), x-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric anal. (TGA), x-ray fluorescence, inductively coupled plasma at. emission spectroscopy (ICP-OES), and brunauer-emmett-teller (BET) surface area anal. The regioselective synthesis of 1,4-disubstituted-1,2,3-triazoles was carried out from reaction of various benzyl halides or alkyl halides with Ph acetylene and sodium azide in water under reflux condition in high yields. The CuO/NiO nanocatalyst can be simply recovered and reused 6 runs without a significant slight in activity. In the experiment, the researchers used many compounds, for example, 1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9Application of 620-19-9).
1-(Chloromethyl)-3-methylbenzene (cas: 620-19-9) 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. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Application of 620-19-9
