Considering the impacts of industrial effluents on the quality of water of many dams and rivers as reported in the literature, a study of water quality of Pench Reservoir (India) has been carried out. In the present work, physico-chemical parameters and bacteriological status are evaluated to determine its suitability for drinking and irrigation. From various parameters like pH, DO, BOD,COD, EC and minerals etc, it is concluded that the water is suitable for drinking. Also contents of chlorides, TDS, SAR, Na%, and RSC are within the limits accepted for irrigation, therefore, the water can be classified as fit for irrigation purpose.

Salicylic acid is a basic nucleus used for the synthesis of different antipyretic, analgesic and antibiotic drugs which are widely used in medicinal field. Various techniques have been used to study intermolecular interactions, one such technique is the measurement of ultrasonic velocity. Ultrasonic parameters provide valuable information about various intermolecular interactions in solution. Measurements of ultrasonic velocity, density and viscosity of 0.01 M solution of salicylic acid in ethanol have been carried out at 303.15 K at different frequencies. The experimental data was used to calculate various acoustical parameters such as adiabatic compressibility (β), apparent molar compressibility (Φ k), specific acoustic impedance (Z), relative association (R A), relaxation time (τ) and intermolecular free length (L f). The results are interpreted in terms of solute - solvent interactions occurring in the solution.

Ultrasonic is a powerful nondestructive technique having wide range of applications in the field of material science. When ultrasonic wave passes through the medium these waves can actively interact with medium and activate the different processes in the medium. Structural changes occurring in the medium are explained in the form of velocity of propagation and amplitude of absorption. These two parameters are used as a function of temperature, pressure and frequency to evaluate several thermo acoustic parameters which gives detailed information about the molecular interaction. Ultrasonic velocity, density and viscosity measurements of Dichlofenac sodium in aqueous media have been made at different concentrations, temperatures and at different frequencies such as 2MHz, 4MHz and 6MHz. The data obtained during the investigation may give information regarding drug absorption, transmission and effect of the drug.

The molecular interaction between solute-solute and solute-solvent was studied with the help of acoustic properties determined by ultrasonic interferometer at 303.15 K in polar acetone and non polar dioxane solvents. The effect of introduction of metal ions viz Cu(II), Fe(in) in die same solution was found out. Also me effect of position of same group at ortho or para position on the molecular interaction was simultaneously examined. © 2011 RASAYAN. All rights reserved.

Recently a new series of biologically active 2-hydroxy-5-methyl-α-H/Substituted thiocarbamido-acetophenones and 3-(2-Hydroxy-3-nitro-5-methyl) substituted-1,2,5-amino/ substituted aminothioxazines have been synthesized in our laboratory. The conditional stability constants of metal-ligand complexes of these compounds with Co(II) and Cr(II) have been investigated in polar and non polar solvents by Job's method of continuous variation, spectrophotometrically. The stiochiometry of complex formation was found to be 1:1.

Density and ultrasonic velocity by interferometer at 2 MHz have been measured for the medicinally important compound 3, 4-dihydroxy-5-nitrobenzaldehyde in ethanol as a solvent at different concentrations at constant temperature 303 K. The data obtained is used to evaluate the different thermodynamic and acoustic properties like adiabatic compressibility, apparent molar compressibility, acoustic impedance, relative association, intermolecular free length etc. From these thermodynamic and acoustic properties, the molecular interactions like solute-solute and solute-solvent occurring in solution have been interpreted, with respect to change in concentration. © 2013 RASAYAN.

2-Hydroxy-3-nitro-5-methyl-a-bromoacetophenone (1) firstly reduced to 2-hydroxy-3-amino-5-methyl-a-bromoacetophenone (2) with treatment of tin and hydrochloric acid. 2-Hydroxy-3-amino-5-methyl-a-bromoacetophenone (2) is further treated with various isothiocyanate (3) such as phenylisothiocyanate (3a), p-chloro-phenylisothiocyanate (3b), p-tolylisothiocyanate (3c), methylisothiocyanate (3d), ethylisothiocyanate (3e) and t-butylisothiocyanate (3f), in presence of acetone-ethanol medium to synthesize 2-hydroxy-3-(3- substituted thiamido)amino-5-methyl-a-bromoacetophenones (4). The products isolated in these reactions were characterized on the basis of conventional elemental analysis, chemical characteristrics and spectral data.
