Document Type and Number:
Japanese Patent JPS5791940
Kind Code:
A
Abstract:
A process for the preparation of phenol ethers from mono- or polyhydric-phenols and aliphatic alcohols with high selectivity is characterized by the use of catalysts containing or composed of superacids, at temperatures from 110 DEG to 170 DEG C, and at phenol: alcohol ratios of from 2:1 to 6:1.
