Title:

METHOD FOR PURIFICATION OF β-PHENYLETHYL ALCOHOL

Document Type and Number:

WIPO Patent Application WO/2008/088074

Kind Code:

A1

Abstract:

Disclosed is a method for the purification of β-phenylethyl alcohol, which comprises supplying β-phenylethyl alcohol to be purified to a distillation column to produce β-phenylethyl alcohol in a purified form as a side-cut fraction. In the method, it is preferred to recycle a fraction collected from the top section of the distillation column into the light boiling substance separation step, from the view point of preventing the loss of β-phenylethyl alcohol in the components present in the top section of the distillation column.
