Abstract

NEW MATERIAL:A 4-oxononanal expressed by formula I and its intermediate, an acetal of the 4-oxononanal expressed by formula II (n is 2 or 3).
USE: An aromatic or flavoring agent or a modifier having a continuous fruity flavor, used for food and drink, cosmetics, healthful and hygienic goods, medicines, etc. Particularly, a compound expressed by formula I is a key flavor giving a flavor and taste of a water melon.
PROCESS: A Grignard reagent expressed by formula III (X is halogen) is reacted with a hexanoic acid or its functional derivative expressed by formula IV (Y is OH, halogen, or O; when Y is OH or halogen, m=1, and when Y is O, m=2) to prepare a compound expressed by formula II. The resultant compound is reacted with an acid, e.g. sulfuric acid, to give the compound of formula I.
