Abstract:
A low expense chloro-monomer, 1-(4'-chloro-1-benzoyl)-3-(4'-1-choro-benzene sulfonyl)-benzene(CBCBSB), was synthesized by the Friedel-Crafts reaction of m-chlorosu1fonyl benzoyl chloride with chlorobenzene. A novel poly (aryl ether sulfone ketone)s (PAESK) containing m-sulfonylbenzoyl linkages in the main chains were prepared by copolycondensation of CBCBSB with hydroquinone in N, N-Dimethylacetamide (DMAc). The structure of PAESK was confirmed by FT-IR, 1H-NMR and characterized by XRD. thermogravimetry (TG) and Differential Scanning Calorimeter (DSC) were carried out to demonstrate its good melt processability. The polymer exhibited the better solubility in chloroform, N-methyl-2-pyrrlidone(NMP), dimethylacetamide(DMAC), dimethylformamide (DMF) and dimethylsulfoxide (DMSO) and excellent mechanical performance.Keywords:

Sonochemical degradation of chlorobenzene in aqueous solutions was studied. The pH of the aqueous solutions of chlorobenzene, the concentration of Cl- ion and chlorobenzene remained were measured. It is found that the chlorobenzene concentrations in aqueous solutions with 1.5721,0.9826, and 0.04912 molm-3 initial concentrations were reduced by 57.6, 40.3, and 30.9% after 120 minutes of sonication respectively. The results showed that the pH of the aqueous solutions dropped gradually, the concentration of Cl- ion was in the same order of magnitude as H+ ion and increased with the reaction time, the chemical kinetics of the reaction for sonochemical degradation of chlorobenzene fitted to the first-order rate law approximately. The mechanism of the sonochemical degradation of chlorobenzene was proposed.

In this paper, the study on the inhibition and recovery of the methanogenic activity of the granular sludge which uncontacted and contacted with chlorobenzene caused by chlorobenzene, and the study of the treatment of organic wastewater containing chlorobenzene by using an EGSB reactor were conducted. The results showed that the activity of the granular sludge which had not contacted with chlorobenzene would be inhibited by different concentrations chlorobenzene; but for the granular sludge which had contacted with chlorobenzene, its activity would be inhibited only by higher concentration (100 mg/L) chlorobenzene. Using EGSB reactor to treat organic wastewater containing chlorobenzene, when the influent chlorobenzene concentration was about 10-50 mg/L, the effluent concentration was lower than 7 mg/L before 65 days, but after the 66th day, the effluent concentration suddenly reached above 25 mg/L, and after stopping adding chlorobenzene, the effluent chlorobenzene concentration was between 3.4-38.32 mg/L, this showed that the high chlorobenzene removal efficiency was mainly due to the strong adsorption by granular sludge, and the biological degradation of chlorobenzene was not obvious.

The adsorption behavior for chlorobenzene from TBBP-A by polymeric macroporous resin was studied.The influences of the initial chlorobenzene concentration,pH and temperature on the adsorption performance were discussed,and the kinetics of chlorobenzene adsorption was explored,and the adsorption isotherms of chlorobenzene at different temperature were measured.The results indicate that the adsorption isotherm of chlorobenzene fits well into the Freundlich adsorption isotherm,and the adsorption kinetic data fits to the pseudo-second-order model;the chlorobenzene adsorption capacity of resin is 267.8 mg/g when chlorobenzene concentration is 6 612 mg/L and pH value is 1-2 at 283 K.

The process of oxidation of toluene, chlorotoluene and chlorobenzene is studied and the optimum parameters for successful implementation of the synthesis modeling industrial processes selected as well. The results obtained in catalytic oxidation of toluene, chlorotoluene and chlorobenzene justify that Ag/MnO2 based catalytic systems have high activeness. Mentioned hydrothermal synthesized catalyst keeps its activeness and properties during the reaction of transition of compounds of toluene, chlorotoluene and chlorobenzene. In the presence of catalysts with Ag/MnO2 nanoparticles, the reaction runs with high percent (90 %) of conversion. The activeness of the catalyst in conversion process of these compounds is optimal with 8000 s-1 volume rate. The optimum temperature for high activeness of toluene, chlorotoluene and chlorobenzene is equal to 543, 490 and 658 К correspondingly. According to the results of analysis on the effect of the components and particles size of catalysts on its activeness, the systems are active in high conversion of the components of Ag/MnO2 + Mn, R-Ag/MnO2 + Ag, R-Ag/MnO2 + Al. These systems containing nanoparticles have high catalytic activeness as well.
