Abstract :

Schiff bases are aldehyde- or ketone-like compounds in which the carbonyl group is replaced by an imine or azomethine group. They are widely used for industrial purposes and also exhibit a broad range of Antimicrobial Activity. The extreme efforts have been developed to design novel series of Schiff ‘s bases with triazole ring (8a and 8b) have been synthesized from 4-Amino-5-((4-amino-5-phenyl-4H-1,2,4-Triazol-3- ylthio)methyl)-4H-1,2,4-Triazole-3-thiol (7), which is built by multiple consecutive cyclization reactions starting from benzoic acid hydrazide (1). Infrared spectroscopy and melting points were used to characterize the synthesized compounds. The biological activity of compounds (7) and (8a and 8b) were evaluated toward gram negative bacteria (Escherichia coli) and gram positive bacteria (staphylococcus aureus).

Abstract :

A kinetic study of dipolar protic solvent on ethyl nicotinate was highlighted by carrying out the varying composition from 30% to 70% (v/v) at five different temperature ranging from 20oc to 40 0c. The specific rate constant values of the reaction found to decrease with gradual addition of ethyl alcohol in water- ethanol media. The value of iso composition activation energy (Ec) and iso-dielectric energy (ED ) values of the reaction were found increase with increase proportion of ethyl alcohol in water- ethanol media. The number of water molecule associated with the activated complex is found to be decrease (1.230 to1.178) in water -ethanol media. The thermodynamic activation parameter such as H*, S*, and G* values of the reaction have been calculated.

Abstract :

Permagnetic oxidation of Benzocaine has been studied at different temperatures using spectrophotometer under acidic conditions. The effect of variation of substrate Benzocaine (BZC), oxidant (KMnO4) and acid H2SO4 was studied under pseudo first order reaction conditions. The effect of different salts and solvents on oxidation of BZC was also studied. The reaction was found to be first order with respect to oxidant, substrate and acid H2SO4 .

Electrical Double Layer Capacitance And Impedance Characteristics of Inorganic Precipitate Membranes
PRADEEP KUMAR JADON (pk_jadon@yahoo.com)
Department of Chemistry, Narain college, Shikohabad- 283135, (U.P.) (India)
Abstract :

To understand the mechanism of ionic diffusion through membranes the membrane resistance, capacitance and impedance of parchment supported Iron phosphate, cupric phosphate and complex ironcupric phosphate membranes have been analyzed. The electrical resistance (Rx), and capacitance(Cx) developed across these membranes have been measured at different electrolyte concentrations and oscillator frequencies.

The obtained  values of membrane resistance(Rm), membrane capacitance(Cm), impedance(Z) were found to dependent on the concentration of the electrolyte and on the applied oscillator frequency at isothermal temperature (25±0.1°C). The electrical double-layer at the membrane-electrolyte interface was influenced and controlled by the transport of ions. An increase in concentration of electrolyte solution causes the counter ions in the form of double-layer inside the membranes makes membrane more conductive. Different model-equivalent electrical circuits against to membranes have been analyzed using the experimental data. There is a deviation from theoretical predictions in Membrane resistance, capacitance and impedance due to roughness and non homogeneity of the membranes used in present investigation.

Abstract :

A single crystal of cerium doped urea thiourea naphthylamine has been grown successfully from its aqueous solution. The grown crystals have been subjected to X-ray diffraction studies to identify the morphology and structure. The TGA-DTA studies showed the thermal properties of the crystals. The functional group of the grown crystals was found by UV - Visible double beam spectra, FT-IR analysis, NMR and XRD studies.
