PROBLEM TO BE SOLVED: To provide a method for purifying β-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-purity β...
The feedstock may be obtained by acetoxylation of toluene followed by hydrolysis, or alternatively, by oxidation of toluene to benzaldehyde followed by reduction to benzyl alcohol . Components in the reactor effluent, e.g., dibenzyl ethers, may be recycled to suppress by-product formation and ...
PURPOSE:The crude product is subjected to azeotropic distillation together with water, a mixture thereof with a dihydric alcohol or with a monoalkyl ether of the dihydric alcohol to produce the titled substance of high purity efficiently through simple operations. CONSTITUTION:Crude beta-phenylethyl ...
BETA-PHENYLETHYL ALCOHOL PURIFICATIONJOSEPH W. BRITTON
Process for the preparation of beta -phenylethyl alcohol from styrene oxide, in which an acid is used for inhibiting the formation of phenylacetaldehyde, and/or in which two catalyst systems are used in reactions carried out in succession for converting phenylacetaldehyde into beta -phenylethyl ...
