B 540 b 5 chi apparatus

A Bruker, Equinox 55 spectrometer was used to record the Fourier transforms infrared (FT-IR) spectra. A Bruker (DRX-400 Avance) nuclear magnetic resonance (NMR) instrument was also used to record the NMR spectra. In addition, a Buchi B-540 B.V.CHI apparatus served to determine the melting points of the compounds. Mass spectrometry spectra were recorded with a Agilent Technology (HP), Model: 5793, Ion source: Electron Impact (EI), 20-EV, 230 °C, and Quadrupole analyzer.

Whole reagents and solvent were procured from Merck, Aldrich and fluka chemical companies. Fourier transform infrared spectroscopy (FT-IR) (ATR or KBr pellets) was run on a Bruker, Eqinox 55 spectrometer. The nanoparticles size and catalyst morphology were ascertained at Field emission scanning electron microscope (FE-SEM) using a Mira 3-XMU. Proton nuclear magnetic resonance (¹H NMR) and carbon nuclear magnetic resonance (¹³C NMR) spectra were record at Bruker (DRX-400 Avance) in DMSO-d₆ as the solvent. The crystallographic characteristics of the sample were obtained by X-ray diffractometer (XRD, Philips Xpert) using Ni-filtered CuKα (kCuK = 0.1542 nm, radiation at 40 kV and 30 Ma) in the 2θ range from 10° to 80°. Thermo gravimetric analysis (TGA) was accomplished using a STA 505 instrument under argon atomosphere. The BET surface area, pore size and pore volume were measured by using Tristar II 3020 analyzer. Melting points were recorded on a Buchi B-540 B. V. CHI apparatus. Energy Dispersive X-ray Spectroscopy (EDS) was measured by Phenom pro X.
