چکیده
Dipole Moments, Diazoketones, Thermodynamic, Dielectric Measurements The electric dipole moments of acetyldiazomethane (MeCOCHN2) and 1-acetyl-1-diazoethane (MeCOCMeN2) between 10 and 70 °C have been measured. Using appropriate group and bond moments, the concentrations of the two rotamers present in each have been calculated and, hence, the equilibrium constant for the cis trans equilibrium at the various temperatures. ^ The change in standard enthalpy (A H°), standard free energy (A G°) and standard entropy (A S°) are reported for the conversion of one mole of cis isomer to trans isomer.

متن کاملA Fugacity Approach for Prediction of Phase Equilibria of Methane Clathrate Hydrate in Structure H
In this communication, a thermodynamic model is presented to predict the dissociation conditions of structure H (sH) clathrate hydrates with methane as help gas. This approach is an extension of the Klauda and Sandler fugacity model (2000) for prediction of phase boundaries of sI and sII clathrate hydrates. The phase behavior of the water and hydrocarbon system is modeled using the Peng-Robinso...
متن کاملThermodynamic Study of the Ion-Pair Complexation Equilibria of Dye and Surfactant by Spectral Titration and Chemometric Analysis
Surfactant-dye interactions are very important in chemical and dyeing processes. The dyes interact strongly with surfactant and show new spectrophotometric properties, so the UV-vis absorption spectrophotometric method has been used to study this process and extract some thermodynamic parameters. In this work, the association equilibrium between ionic dyes and ionic surfactant were studied by a...
