Abstract
PURPOSE: To obtain the carbonyl compound corresponding to a ≥6C olefinic compound (C) industrially advantageously, by oxidizing C in the presence of a specific water-soluble polyoxyalkylene glycol.
CONSTITUTION: A≥6C olefinic compound, (alkyl substituted) styrene, is oxidized in the presence of a water-soluble polyoxyalkylene glycol, preferably a polyoxyethylene glycol (di) methyl ether, wherein m is 6W75, of the formula (R1and R2 are H, 1W8C hydrocarbon groups, m and n are the numbers of oxyethylene or oxypropylene units, m+n≥4, and m>3n) in an aqueous solution containing palladium (or its salt) and a copper salt, preferably at 40W110°C, to give the corresponding carbonyl compound, e.g. phenylacetaldehyde useful as a raw material for perfumes. The amount of the glycol is 0.25W3 times that of water.
EFFECT: Improved reaction rate, selectivity, and separation procedures.
