This Document describes 2 methods for determining the solubility of dyes in organic solvents. This Document applies to dyes that do not undergo chemical changes under the influence of solvents and are stable and non-volatile under specified drying conditions. The applicable dye mass concentration is 1g/L~1000g/L. If the viscosity of the solution satisfies the conditions for smooth operation, higher concentrations can also be used. For volatile solvents (boiling point less than 120 ℃), the gravimetric method is used; for less volatile solvents (boiling point greater than 120℃), the photometric method is used. This Document does not apply to the determination of insoluble matter in dyes.
