Molecular Reorientation of Methanol in Mixtures with Carbon Tetrachloride

چکیده
Proton and oxygen-17 nmr relaxation rates of C D 3 1 7 O H as well as deuteron nmr relaxation rates of C H 3 O D were measured in mixtures with carbon tetrachloride at different compositions and temperatures. By varying the 1 0-content different contributions to the proton relaxation rate could be separated and from the 1 7 0 H dipolar interaction contribution the correlation time of the O H bond was determined. Using these correlation times the composition dependence of the deuterium and oxygen-17 quadrupole coupling constants of methanol was derived. A strong variation of the coupling constants over the measured composition range is evident.

Potential Hepatoprotective Effect and Antioxidant Role of Methanol Extract of Oldenlandia Umbellata in Carbon Tetrachloride Induced Hepatotoxicity in Wistar Rats
The present work examines the protective mechanisms of methanol extract of Oldenlandia umbellata (MEOU) in carbon tetrachloride intoxicated rats. Rats were treated with carbon tetrachloride at the dose of 1 ml/kg body weight intraperitonially once in every 72 hrs for 16 days. The hepatoprotective activity of methanol extract of Oldenlandia umbellata was evaluated by measuring levels of serum ma...
متن کاملDirect acoustic impedance measurements of dimethyl sulphoxide with benzene, carbon tetrachloride and methanol liquid mixtures
Ultrasonic impedance has directly been measured for various binary mixtures using a novel experimental technique. The mixtures are dimethyl sulphoxide with benzene, carbon tetrachloride and methanol at 295 K in different mole fraction ratios. The acoustic impedance of binary mixtures thus obtained was found to be in good agreement with those calculated from experimentally measured ultrasonic ve...

In this study, the hepatoprotective effect of the methanol extract of aerial parts (shoot) from Otostegia persica Boiss (Golder) was investigated against the carbon tetrachloride (CCl4)-induced acute hepatotoxicity in male rats. Liver damage was induced through the oral administration of 50% CCl4 in liquid paraffin (2.5 mL/Kg bw, per os) 60 min after the administration of the methanol extract o...

متن کاملMutual diffusion of binary liquid mixtures containing methanol, ethanol, acetone, benzene, cyclohexane, toluene, and carbon tetrachloride.
Mutual diffusion coefficients of all 20 binary liquid mixtures that can be formed out of methanol, ethanol, acetone, benzene, cyclohexane, toluene, and carbon tetrachloride without a miscibility gap are studied at ambient conditions of temperature and pressure in the entire composition range. The considered mixtures show a varying mixing behavior from almost ideal to strongly non-ideal. Predict...
