摘要： A method of purifying alkylphenyl from impurities contained therein resides in continuous crystallization of alkylphenol and continuous washing of the resulting crystals with a solvent.Washing of the crystals is performed in a layer formed by said crystals, the layer moving downward continuously, with a solvent moving upward.The invention makes it possible to purify alkylphenols effectively and produce them with a high degree of purity with minimum losses of the product, as well as to reduce consumption of the solvent.
