Abstract
PURPOSE: To obtain the titled high-purity substance, by epoxydizing a specific α- olefin in a nonaqueous organic solvent in the presence of an organic acid and hydrogen peroxide to give an oxide, hydrolyzing the oxide, hydrolyzing the oxide after separation in a tertiary alcohol, followed by separating hydrolyzate by distillation.
CONSTITUTION: An α-olefin shown by the formula C2nH4n (n is 6, 7, 8, 9) comprising ≥95wt% single component is epoxydized in a nonaqueous organic solvent in the presence of an organic acid (e.g., formic acid, acetic acid) and hydrogen peroxide to give an oxide, which is separated, hydrolyzed in a tertiary alcohol (e.g., t-butanol), and separated by distillation to give the titled substance. Conditionally the solvent to be used is not oxidized and has a boiling point higher than the reaction temperature, for example, halogenated hydrocarbon, aromatic hydrocarbon, etc. may be cited as the solvent.
EFFECT: The high-purity desired substance is obtaind without using a high level technique, e.g., molecular distillation, etc.
USE: A base for cosmetic, and surface active agent.
