Smectite Clay Modified with Quaternary Ammonium as Oil Remover

Thermal properties of ethylene octene copolymer (Engage)/ dimethyldioctadecyl quaternary ammonium chloride-modified montmorillonite clay nanocomposites

The nanocomposites of ethylene octene copolymer (Engage ) with an organically modified (dimethyldioctadecyl quaternary ammonium chloride) montmorillonite (M-MMT) clay were synthesized by using a solution intercalation technique. The intercalation of M-MMT layers for M-MMT loading of 2.5–7.5% was verified by the shift of X-ray diffraction peak to a lower angle, showing change in basal d-spacing ...

preparation of 3, 4-dihydropyrimidin-2(1H)-ones using quaternary ammonium- treated clay in water

In this study, a variety of 3, 4-dihydropyrimidin-2(1H)-ones derivatives were synthesized via three-component Biginelli reaction. The quaternary ammonium- treated clay -catalyzed process proved to be simple, efficient, and environmentally friendly.
