摘要

Process for the separation of paracresol from mixtures containing phenol, ortho-cresol, metacresol and at least 60% para-cresol, by fractional crystallization, characterized in that the crystallization is carried out in the absence of auxiliary solvents by cooling the crystallization mixture under an initial crystallization temperature that is less than 35º c.
