Determination of wax appearance temperature (WAT) in paraffin/solvent systems by photoelectric signal and viscosimetry

The wax appearance temperature (WAT) is the temperature at which the first wax crystals start to form, on cooling of paraffin/solvent systems. There are a number of different WAT determination methods, including: density and viscosity variation, differential scanning calorimetry, laser dispersio...
