It is related to a kind of ternary system fluid mutual solubility assay method, in addition, further relating to a kind of ternary system fluid mutual solubility measurement system.
Background technology
Currently, measuring fluid mutual solubility/solubility mainly uses cloud point method and analytic approach.Cloud point method is will be pre-configured
Certain density solute and solvent be put into equilibrium still, pressure or temperature are then gradually changed, until observing that a certain phase is opened
Beginning appears or disappears, the solubility under pressure, temperature and known the solute concentration i.e. temperature, pressure at this time.
Cloud point method is divided into as two kinds of constant temperature method and temperature-switching method, since cloud point method is not necessarily to sampling analysis, thus avoids high pressure
