      The intercalation of avermectin (AVM) into sodium dodecyl sulfate (SDS) modified hydrotalcite-like compounds (HTlc) was carried out using an evaporating solvent enhanced intercalation method to obtain AVM-SDS-HTlc nanohybrids. It was found that the nanohybrids could well control the release of avermectin, showing that the nanohybrids are a potential pesticide controlled-release formulation.

      A new copper(II) tetrazolate coordination polymer [Cu(pzta)2]n (1) (pzta=5-pyrazinyltetrazolate) was prepared from the hydrothermal reaction of Cu(OAc)2·H2O with NaN3 and pyrazinecarbonitrile (pzCN) in the presence of ethanol, and characterized by elemental analysis, IR, TGA and X-ray crystallography. The X-ray diffraction analysis of 1 shows that the compound crystallizes in the monoclinic system with space group P2(1)/c and Cu(II) ion center is six-coordinated by four different pzta ligands. The complex 1 features a 2D tetrazole coordination polymer. The thermal analysis of 1 shows that the decomposition of the complex occurs in two regions.

    7. Catalytic Combustion of Ethyl Acetate over Nanostructure Cobalt Supported ZSM-5 Zeolite Catalysts (pages 483–488)

      Aligholi NIAEI, Dariush SALARI, Seyed Ali HOSSEINI, Masumeh KHATAMIAN and Azadeh JODAEL

      Article first published online: 2 APR 2009 | DOI: 10.1002/cjoc.200990079

      Gas phase catalytic combustion of ethyl acetate, as one of volatile organic compounds (VOC), was studied on nanostructure ZSM-5, HZSM-5 and Co-ZSM-5 with different cobalt loadings. Nanostructure of ZSM-5 was determined by XRD, SEM and TEM. Catalytic studies were carried out under atmospheric pressure in a fixed bed reactor. Results showed that the Co-ZSM-5 catalysts had better activity than others and at temperatures below 350 °C, amount of Co loading was more effective on catalytic activity. The order of conversion of ethyl acetate over different Co loading is as follows: Co-ZSM-5 (0.75 wt%)<Co-ZSM-5 (1.5 wt%)<Co-ZSM-5 (15 wt%)<Co-ZSM-5 (2.8 wt%). Besides the higher the inlet concentration of ethyl acetate, the lower the conversion yield, and oxygen concentration in catalytic oxidation conditions has not so large influence on conversion. Furthermore, the presence of water vapor in inlet gaseous feed has an inhibitive effect on ethyl acetate conversion and at the temperatures above 400 °C, the effect decreases.

    8. Flame-retardancy of a Cellulosic Fabric by the Application of Synergistic Effect between Ammonium Bromide and Antimony(III) Oxide (pages 489–493)

      The outcomes of TG curves concerning the flame-retarded supported samples show the similar three stages but with lower decomposition temperatures and mass. The figure also demonstrates TG curve of the flame-retarded cotton fiber and the combined curves respectively. It is obvious that the decomposition temperature of the treated cotton substrate with Sb2O3 is higher compared with untreated one, indicating no influence occurred by using it as a dehydrating agent. Note that both ammonium bromide and its synergy with antimony(III) oxide illustrated a significant role as a dehydrating agent to catalyze the dehydration of the cellulosic substrate, since they lowered the dehydrating temperature around 300 °C.

      Adsorption of nitrogen, hydrogen and methane in square and rectangular nanopores of various sizes has been studied by grand canonical Monte Carlo simulations (GCMC). By comparison of three kinds of potential models, it was found that the site-site model was more rational, which was therefore used in the work. Adsorption behavior of fluids in square, rectangular and cylindrical pores at T=77 K was compared. Prewetting was found in the corners of the square and rectangular pores, which is absent in the cylindrical pores. Adsorption of hydrogen and methane in the three kinds of pores was compared. Among them, the adsorption uptake of hydrogen in the square pore is highest, especially at low pressures, because the effect of potential superposition in the "corners" makes an important contribution to hydrogen adsorption. The results indicate that the presence of corners has a profound effect upon the adsorption and phase behavior of fluids at low pressures.

      In the presence of SCN, Cu(II) was reduced to Cu(I) by isoniazid. The resulting Cu(I) reacted with SCN to develop white emulsion precipitate CuSCN, which was floated on the surface of water when NaNO3 was added into the solution. By determining the amount of residual Cu(II) in the water phase, the amount of isoniazid could be obtained.

      The thermodynamics and extra-thermo- dynamics of Bacillus subtilis α-amylase in some chromatographic systems were studied. It was found that their adsorption procedures were driven by both of the enthalpy change and the entropy change on some chromatographic media, while on some other chromatographic media, their adsorption procedures were driven only by the entropy change; and for α-amylases on a RP-C18 reversed-phase medium (⋄), a Zn-chelated Sepharose fast-flow affinity medium (□), a WCX-1 cation-exchange media (Δ), a PEG-400 hydrophobic medium (◯) and a modified PEG-400 medium (∗), their enthalpy-entropy compensation relationships lay on the same straight-line and their enthalpy changes could be compensated only with their entropy changes rising from their conformational change.
