Adjacent hydroxy benzene ether is important, and the fine chemical intermediates for the purified is of major importance, this design through its atmospheric distillation for a single study, no longer rough, relieving pressure to remove the residue contamination, which can ultimately be purity great

The neighbouring hydroxyl phenetole for the important fine chemical intermediate, has the great significance to its separation depuration, this design through carries on the atmospheric distillation to it to obtain the monoether thickly, again carries on the rectification under vacuum to remove impu

O-phenyl ether as an important fine chemical intermediates, on separation and purification of its significance, this design through the crude atmospheric distillation it access to single ether, then vacuum distillation to remove impurities, eventually finished o-phenyl ether under purity greater tha
