I found the field of Chemistry very interesting. Saw the article Aqueous Media Synthesis of Pyrano[3,2-c]chromen Derivatives Using Magnesium Oxide Nanoparticles as a Recyclable Catalyst published in 2021. COA of Formula: C7H5NO3, Reprint Addresses Ghashang, M (corresponding author), Islamic Azad Univ, Dept Chem, Najafabad Branch, POB 517, Najafabad, Iran.. The CAS is 99-61-6. Through research, I have a further understanding and discovery of 3-Nitrobenzaldehyde
Here, the synthesis of MgO nanopowders via a simple precipitation method is defined. The morphology, phase identification, particle size distribution and specific surface area of the sample was investigated by FE-SEM, TEM, XRD, DLS, and BET techniques. The structural parameters were determined through XRD pattern. The sample crystallized in a pure cubic phase with the average crystallite size of 55 nm. The micro-strain (epsilon) and dislocation density (delta) of the sample were also calculated to be 0.1153 and 3.306 x 10(-4), respectively. The catalyst has a specific surface area and of 26.7 m(2)g(-1). The catalytic activity of MgO nanopowders was studied in the three-component condensation of aldehydes, 4-hydroxycoumarin, and malononitrile in aqueous media. A range of aromatic aldehydes undergoes the reaction to produce a series of pyrano[3,2-c]chromen derivatives in good yields.
