Abstract:
There is provided a process for reacting phenol with butene or butanol over fairly large-pore zeolites to give butylphenol with high para-selectivity. Particular zeolites for use in this reaction include ZSM-12 and zeolite beta. A particular butene or butanol reactant is isobutanol. The product of this reaction may have a high content of the mono-alkylated, tert-butyl product.
