Abstract
A method of purifying an alcoholphenol from impurities contained therein, by crystallization and washing of the resulting crystals with an inert solvent for the alcoholphenol, characterized in that the crystallization of the alcoholphenol, characterized in that the crystallization of the alcoholphenol is effected continuously, the alcoholphenol being fed to a speed comprised between 0.12 and 0.31 hr-1, and the crystals being washed in a layer formed by said crystals, and which descends at a speed of 0.1 to 1.0 hr-1; washing with a solvent that moves in countercurrent at a speed of 0.09 to 0.35 hr-1.
