<p><P>PROBLEM TO BE SOLVED: To provide a method for purifyingβ-phenylethyl alcohol with which an off-flavor component produced in a purifying column is efficiently and selectively separated and removed only by simple operation without requiring a complicated apparatus or operation and the high-purityβ-phenylethyl alcohol having an excellent fragrance for perfumes can be obtained. <P>SOLUTION: The method for purifying theβ-phenylethyl alcohol with which theβ-phenylethyl alcohol to be purified is fed to a rectifying column and theβ-phenylethyl alcohol purified as a side cut is obtained. The fraction obtained from the column top of the rectifying column is preferably recycled to a light-boiling separation step from aspects that the loss of theβ-phenylethyl alcohol in the overhead component can be suppressed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
