Verfahren zur Abtrennung von 2,3,6-Trimethylphenol aus einem Xylole und/oder Trimethylphenole enthaltenden Phenolgemisch

摘要

2,3,6-Trimethylphenol is recovered in high yield and high purity from its admixture with di- and tri-methyl-substituted phenols by subjecting the admixture to the sequential steps of butylation, fractional distillation, debutylation, and finally, fractional distillation.
