Isomerization of Cresols. |
摘要 |
<p>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 crystalline aluminosilicate zeolite catalyst and added hydrogen. The added hydrogen will provide stability and longer life to the catalyst as well as a more stable selectivity to the desired isomers. The isomerization reaction is effected at temperatures ranging from about 250 DEG to about 450 DEG C. and pressures ranging from 2 to about 75 atmospheres in the presence of added hydrogen, said hydrogen being present in a mole ratio in the range of from about 1:1 to about 10:1 moles of hydrogen per mole of cresol.</p> |
