Purification of 2,6-xylenol streams |
摘要 |
2,6-xylenol admixed with meta,para-cresol is reacted with methanol in a contact with a titanium/SO4/magnesium oxide catalyst to yield a product stream which can be readily distilled to give 2,6-xylenol in high purity. The particular catalyst used allows low loss of 2,6-xylenol during the reactions and low amounts of side products obtained.
