      Molecular dynamics simulation has been used to study the interactions between calcite crystal and seven kinds of phosphonic acids. The results indicate that the sequence of scale inhibition performance of all phosphonic acids against calcite scale is EDATMP>HDATMP>HEBP>NTMP>GBMP>HEBP>NMBMP, and the inhibition against the growth of (1l̄0) crstal face is on the dominant status; phosphonic acids are deformed during the combination process; electrovalent bonds formed between the calcium ions in scale crystal and the phosphoryl oxygen atoms in phosphonic acids.

      Two surfactants (A and B) of alkylbenzenesulfonate type with different carbon chains have been studied in terms of adsorption on oil sands for chemical flooding applications to oilfields. Surfactant adsorption on the sands heavily depends on its lipophilicity, and the adsorption quantity increases with increasing the lipophilic chain length of the surfactant.

      A batch system was applied to study the adsorption behavior of methylene blue (MB) and rhodamine B (RB) in single and binary component systems on natural zeolite. In the single component systems, the zeolite presents higher adsorption capacity for MB than RB with the maximal adsorption capacity of 7.95×10−5 and 1.26×10−5 mol/g at 55°C for MB and RB, respectively.

    4. DFT Study of N2O Activation with La+, Hf+, Ta+ and W+ in the Gas Phase (pages 357–362)

      Jianhui Zhang, Yongcheng Wang, Yanli Leng and Fengxian Li

      Article first published online: 31 MAR 2010 | DOI: 10.1002/cjoc.201090079

      The spin-forbidden reaction N2O(X1Σ)+M+[RIGHTWARDS ARROW]N2(X1Σ+g)+MO+ (M+=La+, Hf+, Ta+, W+) was discussed using density functional theory. The reaction mechanism between M+ transition metal ions and N2O is an insertion-elimination one. All products are formed in exothermic processes. In comparison with the previous work, an essential conclusion could be drawn that the reaction N2O(X1Σ)+CO(1Σ+)[RIGHTWARDS ARROW]N2(X1Σ+g)+CO2(1Σ+g) catalyzed by M+ was endothermic by 358.89 kJ·mol−1 which is in accord with the experiment finding.

      The photophysical properties of N,N-bis(pyrimidenyl)-3,4,9,10-perylenetetracarboxylic diimide (PmPBD), N,N-bis(pyridenyl)-3,4,9,10-perylene-tetracarboxylic diimide (PyPBD) and N,N-bis(4-methylpyridenyl)-3,4,9,10-perylenetetracarboxylic diimide (MPyPBD) have been measured in different solvents. Both electronic absorption and fluorescence spectra are not sensitive to medium polarity, while the fluorescence quantum yield is solvent dependent. Perylene derivatives under investigation undergo molecular aggregation to dimmer or larger aggregates in water. The value of energy transfer rate constant and critical transfer distance indicate a F?rster type energy transfer mechanism. There is a large interaction between the perylene compounds under investigation and the hydrated nanoparticles in the excited state therefore the fluorescence quenching rate constant of these derivatives by hydrated iron oxide nanoparticles has a large value.

      Divya Shukla, Shashi Singh, Shahla Parveen, Manisha Gupta and Jagdish Prasad Shukla

      Article first published online: 31 MAR 2010 | DOI: 10.1002/cjoc.201090081

      Ultrasonic velocity (u) and density (ρ) were measured for the binary mixtures formed by heptane with ethyl acetate or butyl acetate at temperatures 293, 298 and 303 K over the entire composition range. Deviation in ultrasonic velocity (Δu), deviation in isentropic compressibility (Δκs), and excess intermolecular free length (LEf) have been evaluated using the ultrasonic velocity data and the computed results were fitted to the Redlich-Kister polynomial equation. The values of Δu, Δκs and LEf were plotted against the molar fraction of heptane. The observed positive and negative values of excess parameters were discussed in terms of molecular interaction between the components of the mixtures. Experimental values of ultrasonic velocity and density were compared with the results obtained by theoretical estimation procedures. The results were discussed in terms of average absolute deviation (AAD).

The synthesis of benzyl acetate was carried out with H2SO4/ammonium cerium phosphate as catalyst, and uniform experimental design as well as data mining technology was applied to the experiments, in which the effect of the reaction time, the molar ratio of acid to alcohol and the amount of catalyst on the conversion yield of acetic acid were studied. Under the optimal reaction conditions, the esterification rate of acetic acid was 97.9%.

For β-aryl substituted α,β-unsaturated ketones and esters such as 4-aryl-3-buten-2-ones, chalcones and methyl cinnamate, the [4+2] reactions could proceed smoothly at room temperature to afford 6-acyl-5,6,6a,11-tetrahydroisoindolo[2,1-a]quinolin-11-ones and 4-acyl-1,3a,4,5-tetrahydropyrrolo[1,2-a]quinolin-1-ones or 4-acyl-1,2,3,3a,4,5-hexahy-dropyrrolo[1,2-a]quinolin-1-ones in moderate to high yields; while for simple α,β-unsaturated ketones and esters such as methyl crotonate and ethyl 3-methylbut-2-enoate, except mesityloxide, the [4+2] reactions were difficult to proceed. The cycloaddition reactions were highly stereoselective, and only one stereoisomer was produced in each reaction.
