Kauri-butanol value

The Kauri -butanol value ( " Kb value") is a measure of the solubility of an organic solvent and is determined according to the ASTM standard ASTM D1133. The higher the solubility, the higher is the unitless value Kb. Weak solvent are between about 10 and 20 may reach values ​​of chlorinated solvents in the hundreds field. It is an alternative to the aniline point and is given in hydrocarbon solvents.

The dimensionless value is determined by the cloud point of the titration of a kauri resin - butanol solution against the solvent.
