Production of fatty acid ethyl esters from rubber seed oil in hydrodynamic cavitation reactor: Study of reaction parameters and some fuel properties

Series of coordination complexes of Ni(II), Cu(II), Zn(II), Cd(II) and Sn(II) metal with 4-amino-5-(pyridyl)-4H-1,2,4-triazole-3-thiol, as a ligand has been successfully prepared in alcoholic medium. The prepared complexes were characterized quantitatively and qualitatively by using: microelemental analysis, FTIR spectroscopy, UV-visible spectroscopy, 1H and 13C NMR, magnetic susceptibility and conductivity measurements. This triazole ligand act as bidentate that coordination to the metal ions through sulphur and amine group. According to the spectral data of the complexes a tetrahedral geometry was suggested for these complexes except Cu (II) complexes which exhibit a square structure.

Synthesis of 2-N-salicylidene-5-(substituted)-1,3,4-thiadiazole as potential antimicrobial agents

New metal complexes of the ligand 2-thioacetic-5-phenyl-1,3,4-oxadiazole with the metal ions Ni(II), Cu(II), Zn(II), Cd(II) and Sn(II) were prepared in alcoholic medium. The prepared complexes were characterized by FTIR Spectroscopy, electronic spectroscopy, mass spectroscopy 1H NMR, 13C NMR, magnetic susceptibility and conductivity measurements. From the spectral measurements, monomer structures for the complexes were proposed. Square planar geometry was proposed for the copper complex. The other complexes were proposed to be tetrahedral. Preliminary in vitro tests for antimicrobial activity show that all prepared compounds display good activity to Staphylococcus aureus, Escherishia coli, Pseudononas aeroginosa and Cndida albicans.

Enhancement of Photostabilization of Poly(vinyl chloride) Doped with Sulfadiazine Tin Complexes

New diorganotin (IV) complexes of the type Ph2SnL2, Bu 2SnL2 and Me2SnL2 of the ligand benzamidocysteine (LH). Ligand formed by reaction of benzoyl chloride with cysteine in presence of sodium hydroxide. The prepared complexes were characterized by elemental analysis, infrared, conductance measurements and nuclear magnetic resonance ( 1 H, 13 C and 119 Sn NMR) spectral data. From the spectral measurements, monomer structures for the complexes were proposed. Bidentate and Octahedral geometry was proposed for the complexes prepared. Preliminary in vitro tests for fungicidal activity show that all prepared compounds display good activity to Gibberela, Cercospora arachidicola, Physolospora piricola and Fusarium oxysporum.

Synthesis and fungicidal activity of some diorganotin(iv)with benzamidocysteine

Physicochemical and instrumental characterization of rubber (Hevea brasiliensis (kunth. Muell.)) seed oil (RSO) were carried out for the purpose of quality assessment, identification, and authentication. Properties such as free fatty acid (FFA %), acid value, color, saponification value, iodine value, and unsaponifiable matter were determined. Fatty acid (FA) composition and TAG profiles were determined using gas chromatography (GC) and high performance liquid chromatography (HPLC), respectively. Structural features of RSO were also determined using FTIR, 1 H NMR and 13 C NMR spectroscopy. The natural form of RSO is highly acidic (acid value=17.43±0.06 mg KOH/g). The saturated FAs are palmitic (9.10±0.06) and stearic (12.63±0.01), and the main unsaturated FAs are oleic (25.31±0.13), linoleic (36.31±0.09), and linolenic (15.78±0.18). The oil can be classified as semidrying. Polyunsaturated TAGs of LnLnL and LnOO were the major TAGs found in RSO. FTIR, 1 H NMR and 13 C NMR analysis confirmed
