Preparation, spectral analysis of a substituted phenyl acetanilide from aniline.

For the synthesis of acetanilide from aniline, magnesium sulfate-glacial acetic acid system is a safe, environmentally friendly, and reasonably priced catalyst. The procedure is quick, easy, and environmentally friendly, does not require hazardous acetic anhydride, and uses a catalyzed reaction in accordance with green chemistry principles. The technique is simple to use at the undergraduate level and might be used to acetylate primary and secondary amines on a large scale in industry. The crystal that was treated using the aforementioned approach underwent numerous characterisation analyses. The sample's crystalline nature was confirmed by the powder X-ray diffraction technique. The crystal's functional group was located via FT-IR spectrum analysis. UV-Visible investigations looked at the crystals' transparency and optical characteristics. Through differential thermal analysis and differential scanning calorimetry (DTA/DSC), the thermal stability of the formed crystal was analysed. To display the molecular structure, 1HNMR spectra was analysed. The crystal's band gap value supports the material's application-oriented features. [ABSTRACT FROM AUTHOR]
