Title:
METHOD FOR PURIFICATION OF BETA-PHENYLETHYL ALCOHOL
Document Type and Number:
Japanese Patent JP3858512
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To purify β-phenyletyl alcohol useful for perfumes, etc., without requiring complicated devices and operations and efficiently separating and removing nasty smell components by washing crude β-phenylethyl alcohol with an aqueous alkali solution, extracting it and distilling the extract.
SOLUTION: Crude β-phenylethyl alcohol is purified by washing the crude β-phenylethyl alcohol with an aqueous alkali solution such as an aqueous sodium hydroxide solution or the like in an alkali washing tank 3, subsequently extracting and distilling the washed crude β-phenylethyl alcohol in an extracting and distilling tower 7. The extracting solvent is preferably one or more of solvents selected from (i) water, (ii) a mixture solution of water with 1,2- ethanediol or 1,2-propanediol, (iii) a mixture solution of water with 1,2-theanediol monomethyl ether, 1,2-theanediol monoethyl ether, or the like.
