Cocrystal of 4-Nitrophenol and 2,1,3-Benzoselenadizole

open access: yesMolbank, 2023
The 1:1 cocrystal of 4-nitrophenol (NP) and 2,1,3-benzoselenadiazole (BSA) was successfully synthesized. The X-ray single-crystal diffraction analysis revealed that the structure contained a [Se–N]2 cyclic supramolecular synthon.

Glauconite as a sorbent of 4-nitrophenol [PDF]

open access: yesIzvestiya of Saratov University. New Series. Series: Chemistry. Biology. Ecology, 2021
The sorption properties of glauconite from Beloozersk deposits (Saratov region) for 4-nitrophenol (4-NF) have been investigated. The effect of glauconite on pH and 4-nitrophenol structure in solution is estimated. It is shown that glauconite increases pH of aqueous environment to 8 and shifts the equilibrium towards the formation of aci-form 4-NF.
