Prediction of solid–water–hydrocarbon contact angle
چکیده انگلیسی

The reliability of a recently developed solid–vapour and solid–liquid interfacial tension models has been investigated by applying them to predict liquid–vapour and liquid–liquid interfacial tension values. The impact of the geometrical molecular packing and the molecular orientations near the surface on the predicted values are discussed. The mutual solubility data are shown to be adequate for calculation of the interaction parameters in the solid–liquid model and a new equation, using this information, is developed for prediction of water–hydrocarbon interfacial tension. The model has been applied to recent data on water–methane–n-decane and water–methane–cyclohexane–n-decane interfacial tensions at elevated temperature and pressure and its reliability demonstrated. It is shown that the solid–liquid interfacial tension model is solely adequate for predicting the contact angle by applying it to mercury–water–benzene and stearic acid–water–n-decane systems.

It is shown that the solid–liquid interfacial tension model along with the solubility data is solely adequate for predicting the contact angle.Figure optionsDownload as PowerPoint slide
