in this study adsorption of 1-chloro-4-nitrobenzene on single walled carbon nanotubes has been investigated.  the effect of contact time, ph, initial concentration of 1-chloro-4-nitrobenzene, adsorbent dosage and temperature on its adsorption has been carried out in order to find optimum adsorption conditions. adsorption isotherms and related constants were also determined. results showed that ...

Pseudomonas sp. WR912 was isolated by continuous enrichment in three steps with 3-chloro-, 4-chloro-, and finally 3,5-dichlorobenzoate as sole source of carbon and energy. The doubling times of the pure culture with these growth substrates were 2.6, 3.3, and 5.2 h, respectively. Stoichiometric amounts of chloride were eliminated during growth. Oxygen uptake rates with chlorinated benzoates reve...

Overexpression of mutant p53 in cancer cell inactivates the pathways to execute apoptosis and cycle arrest. This study aimed synthesize new kardiena derivative compound, 3-carbethoxy-4(3’-chloro-4’-hydroxy)phenyl-but-3-en-2-one, reactivate Characterization synthetic compound employing melting point, IR, EI-MS, 1H-NMR, 13C-NMR spectra revealed 3-carbethoxy-4(3’-chloro-4’-hydroxy)phenyl-but-3-en-...

In the title compound, [CoCl(2)(C(12)H(14)ClN(3))(2)], the central Co(II) ion lies on a twofold rotation axis and adopts a distorted tetra-hedral coordination geometry defined by two N atoms from two 2-(2-chloro-ethyl)-1,2,3,4-tetra-hydro-pyrazino[1,2-a]benzimidazole ligands and two chloride anions. The Cl atom located in the side chain of the ligand is involved in inter-molecular C-H⋯Cl hydrog...

this research evaluates the efficiency of nanosized zno in the catalytic ozonation of 4-chloro-2-nitrophenol and determines the effect of ph on heterogeneous catalytic ozonation. the combined use of ozone and zno catalyst leads to conversion of 98% 4-chloro-2-nitrophenol during 5 min. in addition, it was found that in zno catalytic ozonation, the degradation efficiency of 4-chloro-2-nitrophenol...

The title compound, C(14)H(11)ClO, is a racemic derivative of benzoin. Its carbonyl group adopts a nearly eclipsed conformation with the Cl substituent characterized by a dihedral angle of 17.5 (2)°. The closest intermolecular π-π contact is 4.258 (1) Å.

In the title hydrated salt, C7H9ClN(+)·Cl(-)·H2O, the organic cations, anions and water mol-ecules are connected by N-H⋯Cl, N-H⋯O and O-H⋯Cl hydrogen bonds. These inter-actions lead to the formation of layers parallel to the ac plane.
