Bentonite-based nano organic clay using chalcone and azo dye as organophilic reagents

Abstract

Organclays (OBNTs) were prepared using two new organic surfactants including 3-(4-aminophenyl)- 1-(4-chlorophenyl)prop-2-en-1-on (CH) synthesized from a Claisen-Schmidt condensation reaction between p-aminoacetophenone and p-chlorobenzaldehyde; and 4-((4-nitrophenyl)diazenyl)-N- (pyrimidin-2-yl) (AZ) prepared from reaction of sulfadiazine and p-nitoaniline. Organclays OBNTs were characterized by Fourier transform infrared spectroscopy (FTIR) to evaluate the incorporation of surfactants in bentonite. The X-ray diffraction (XRD) technique was utilized to indicate the basal spacing of the treated clay as a measure of susceptibility of new organoclays. The FTIR and XRD results showed that the OBNTs were successfully incorporated in the layers of bentonite clay. Thermogravimetric analysis (TGA) was also used to determine thermal stability. An enhancement in stability was observed in OBNTs compare to pure bentonite. OBNTs prepared in this study can be used to produce disposable packaging a promising polymer nanocomposite.
