CONVERSION OF META/PARA-CRESOL MIXTURE

The instant invention relates to a process for the conversion of meta/para-cresol mixtures by catalytically methylating the meta/para-cresol mixtures in their ortho-positions, separating the 2,3,6- and 2,4,6-trimethylphenols formed and converting subsequently the 2,4,6-trimethylphenol in the presenc...

Zusammenfassung:	The instant invention relates to a process for the conversion of meta/para-cresol mixtures by catalytically methylating the meta/para-cresol mixtures in their ortho-positions, separating the 2,3,6- and 2,4,6-trimethylphenols formed and converting subsequently the 2,4,6-trimethylphenol in the presence of iron oxide(s) or catalysts which contain iron oxide(s) and at least one additional oxide, to a mixture of methyl phenols, which is essentially free from meta-substituted methylphenols.
