abstract |
The crystallization temperatures of two binary systems - tetradecane + hexadecane and tetradecane + pentadecane - were measured under high pressure up to 100MPa using a polar microscopy device. The slopes of the melting curves in the (T, P) diagram show a dependence on the nature of the different solid phases that can appear. The effect of pressure on the liquidus curve in a (T, x) diagram is discussed and represented in the last part of this work with an excess Gibbs energy model, slightly modified to take the different solid phases into account.
