Dyestuffs - Determination of solubility in organic solvents - Gravimetric and photometric methods
Also Known As:
This International Standard specifies a method for determining the solubility of dyestuffs in organic solvents. It is applicable to dyestuffs that do not change chemically under the influence of the solvent, are stable and non volatile under the specified drying conditions. For volatile solvents (boiling point lower 120 °C) we generally recommend a gravimetric, for less volatile solvents (boiling point greater 120 °C) a photometric procedure. The individual selection should be taken on a problem specific base. The method is suitable for concentrations between 1 g and 1000 g of dyestuff per litre of solvent. In case of higher concentration the viscosity of the test solutions must be suitable for the described procedures. The method is not suitable for the determination of insoluble matter in a dyestuff.
