Characterisation of Reactions in Supercritical Difluoromethane
Reactions in scCO2 are frequently limited by the low polarity of the solvent. This may result in low solute/ product solubility or low catalyst activity. The use of more polar sc fluids such as difluoromethane (HFC 32) can circumvent many of these issues and facilitate reactions that are not possible in CO2. We demonstrate the use of HFC 32 for three types of reaction; an esterification reactio...
متن کاملKinetics inversion of chloro-olefine in the solid acid system
The reaction kinetics of the isomerization 3,4-dichlorobutene-1 to 1,4-dichlorobutene-2 was investigated by using gas-liquid chromatography method in the presence of Fe2O3/MgO as solid catalyst in the temperature range 25-55°C. Fe2O3/MgO has been prepared by the support saturation method, tested in the isomerization of 3, 4-dichlorobutene-1 into 1, 4-dichlorobutene-2. This catalyst shows a high...
متن کاملPrediction of Vapor-Liquid Equilibria Using CEOS /GE Models
The present study investigates the use of different GE mixing rules in cubic equations of state for prediction of phase behavior of multicomponent hydrocarbon systems. To predict VLE data in multicomponent symmetric and asymmetric mixtures such as systems that contain light gases (nitrogen, carbon dioxide, etc.) and heavy hydrocarbons, the SRK equation of state has been combined with excess Gib...

متن کاملThermodynamic Properties of Difluoromethane on the Saturation Curve
Vapor pressures in the range of 256 to 331 K and saturated liquid and vapor densities from 315 to 331 K have been measured for difluoromethane (HFC-32) on the saturation line by means of variable volume and static experimental methods. Our results have been combined with literature values, and on the basis of all the measurements, accurate analytical correlations for saturated liquid and vapor ...
