Extraction Parameters

Three new extractants for palladium(II) extraction: bis(noctyl-Sulfinyl-ethyl) ether(L1), bis(isooctyl-Sulfinyl-ethyl)ether(L2), bis(isooctyl-Sulfinyl-ethoxy)ethane(L3) were synthesized. Micro-analytical data, elemental analysis, 1HNMR and IR-spectra were used to confirm the structures. Based on independent extraction experiments of Pd(II) , the extraction parameters of Pd(II) were studied in detail, and the optimal extraction parameters were obtained and summarized as the following: H+ concentration of aqueous phase 1.0-1.5 mo1·L-1, sulfoxide extractants concentration 0.01-0.1 mo1·L-1. The order of the extractability of the three extractants towards palladium(II) was L2>L3>L1. The coordination number was studied by the slope method. The results indicated that, in low acidity, the coordination number for extracting palladium (II) was 1.0 with all three extractants, while it was 2.0 in high acidity. FT-IR spectra was used to analyze the structure of the complex. Palladium (II) was coordinated with the oxygen atom in S=O group of the three extractants. and palladium (II) may also coordinated with the oxygen atom in C-O-C group of extractant L1, L2.

In this paper, some chalcone derivatives (C1, C2) were synthesized based on the reaction of equal amount of substituted acetophenone and substituted banzaldehyde in basic medium. Oxazine and thiazine derivatives were prepared from the reaction of chalcones (C1-C2) with urea and thiourea respectively in a basic medium. Pyrazole derivatives were prepared based on the reaction of chalcones with hydrazine mono hydrate or phenyl hydrazine in the presence of glacial acetic acid as a catalyst. The new synthesized compounds were identified using various physical techniques like1 H-NMR and FT-IR spectra.

The synthesis of tetra and octa perfluoroalkyl substituted zinc and metal free phthalocyanines ( ZnPc and H 2 Pc ) are reported. The compounds 1–5 have been prepared by nucleophilic substitution of 4-nitrophthalonitrile with 1H,1H,2H,2H-perfluorooctanethiol, 1H,1H,2H,2H-perfluorodecan-1-ol, 1H,1H-perfluorodecan-1-ol, 1H,1H-perfluorotetradecan-1-ol and 1H,1H-perfluoro-3,6,9-trioxatridecan-1-ol, respectively. The compounds 6–8 have been prepared by the reaction of 1H,1H,2H,2H-perfluorodecan-1-ol, 1H,1H-perfluorodecan-1-ol and 1H,1H-perfluoro-3,6,9-trioxatridecan-1-ol with 4,5-dichlororphthalonitrile, respectively. The compound 9 with thia-bridge has been synthesized from 4,5-dichlororphthalonitrile. Zinc and metal free phthalocyanines were obtained from the corresponding phthalonitrile derivatives. All compounds were characterized by using mass, 1 H , 19 F NMR, UV-vis and FT-IR as well as elemental analysis. Tetra substituted Zn ( II ) phthalocyanines are slightly soluble only in THF (Compound 4a and 7a are insoluble) but metal free phthalocyanines are not soluble. Octa substituted Zn ( II ) and metal free phthalocyanine are soluble in polar solvents such as THF and DMSO.

In this study, a new series consisting of 12 heteroaryl chalcone derivatives of 1,3,5-trimethoxybenzene were synthesised. Chalcones were synthesised in high purity and efficiency, via condensation of mono, bis and tris 2,4,6-trimethoxy acetophenones with hetero-2-carbaldehyde derivatives based on Claisen Schdmit condensation. The reactions feature a good scope for the all products, mild reaction conditions and good yields. The synthesized compounds were characterized by using FT-IR, NMR and elemental analysis spectroscopic techniques.

Novel polymers with imide and ether were synthesized by pyromellitic dianhydride and Pyromellitic dianhydride (PMDA), 4,4'-metylenedianiline (MDA), amino-teminated polyoxypropylene (D2000). The structures and thermostability of polymer were characterized through FT-IR spectra, thermogravimetric analysis (TGA) and differental scanning calorimetry (DSC), solubility behavior was determined via seven solvents. The results indicate that these polymers have good chemical resistance and exhibit excellent thermostability owing to the introduction of imide units.
