    • An improvement in a process for the isomerization of cresols may be obtained by effecting the isomerization reaction of a cresol in the presence of a phosphorous containing crystalline aluminosilicate zeolite catalyst. The added phosphorous provides stability and longer life to the catalyst as well as more stable selectivity to the desired isomers. The isomerization reaction is effected at temperatures ranging from about 350.degree. C. to about 500.degree. C., pressures ranging from about 1 to about 60 atmospheres, a Liquid Hourly Space Velocity that ranges from 1 to about 5 hours.sup.-1, with the abovementioned catalyst containing from about 1% to about 8% by weight phosphorous.
    • 通过在含磷结晶硅铝酸盐沸石催化剂的存在下进行甲酚的异构化反应,可以获得甲酚异构化方法的改进。 添加的磷提供催化剂的稳定性和更长的寿命以及对所需异构体的更稳定的选择性。 异构化反应在约350℃至约500℃的温度下进行,约1至约60个大气压,约1至约5小时-1的液体小时空间速度与上述 催化剂含有约1%至约8%重量的磷。
