Model 8300 ft ir spectrophotometer

All chemicals were either prepared in our laboratory or were purchased from Merck and Fluka. Reaction monitoring and purity determination of the products were accomplished by GLC or TLC on silica-gel polygram SILG/UV 254 plates. Gas chromatography was carried out on Shimadzu GC 14-A. IR spectra were obtained by a Shimadzu model 8300 FT-IR spectrophotometer. 1 (link) H NMR spectra were recorded on 400 MHz spectrometer in CDCl 3 . TGA was carried out on a Stanton Redcraft STA-780 with a 20 °C/min heating rate. Melting points were determined on a Fisher-Jones melting-point apparatus. XRD patterns were recorded by a Phillips X-ray diffractometer using graphite monochromatized Cu Kα radiation. A morphological study of the synthesized products was carried out directly by a Hitachi S4160 field emission scanning electron microscope (FESEM). Room temperature magnetic properties were investigated by Lakeshore device in an applied magnetic field sweeping between ±8000 Oe.

Chemicals were purchased from Merck and Fluka chemical companies. IR spectra were run on a Shimadzu model 8300 FT-IR spectrophotometer. NMR spectra were recorded on a Bruker Avance DPX-250. The purity of the products and the progress of the reactions were determined by TLC on silica-gel polygram SILG/UV254 plates. Elemental analysis was performed on a Thermo Finnigan (San Jose, CA, USA) Flash EA micro analyzer.

IR spectra were obtained by a Shimadzu model 8300 FT-IR spectrophotometer. 1 (link) H NMR spectra were recorded on 400 MHz spectrometer in CDCl 3 . The Leco sulfur analyzer was used for the measurement of sulfur in the catalyst. TGA was carried out on a Stanton Redcraft STA-780 with a 20 °C/min heating rate. SEM and TEM images were taken with a Hitachi S-3400N scanning electron microscope and a Philips CM10 transmission electron microscope, respectively. Melting points were determined on a Fisher-Jones melting-point apparatus.
