Technology for the isomerization of o-cresol to m-cresol and p-cresol

I would like to ask everyone: Is there any mature process technology in China for the isomerization of o-cresol to produce m-cresol and p-cresol at present? It is only known that a molecular sieve catalyst is used, but it seems that the one-pass conversion rate of o-cresol is not high, at around 50% only. Furthermore, in the product, the boiling point difference between m-cresol and p-cresol is extremely small, less than 1 degree Celsius. Therefore, the separation and purification of the subsequent products is also one of the technical challenges; those who are aware of this are invited to discuss it.
