摘要： PURPOSE:To obtain the titled compound useful for improving the flavor of a food and drink, table luxuries, tobacco, etc. and the frangrance of a cosmetic, industrially, readily, safely and selectively, by oxidizing a beta-ionone enol ester with oxygen in a nonpolar solvent. CONSTITUTION:A beta-ionone enol ester of formula (7) is oxidized with oxygen in a nonpolar solvent, e.g. henzene, to form a mixture of beta-ionones expressed by formulas (2), (3), (8) and (5). A compound of formula (2) in which X is O in the titled compound of formula I (X is O, OH or alkoxyl) is separated and extracted from the reaction product. The yield of the compound of formula (2) is increased by the addition of a dehydrating substance, e.g. magnesium sulfate or calcium chloride, and the compound of formula (3) and a 4-alkoxy-beta-ionone in the titled compound are obtained selectively by changing the reaction conditions.

摘要： PURPOSE:A cigarette beetle repellent that contains a specific fatty acid as an active igredient, thus being inexpensively available and showing the effect of preventing female beetles from ovipositing with an extremely small amount of application. CONSTITUTION:The objective repellent contains, as an active ingredient, a fatty acid of the formula (n is 6-11), e.g., n-caprilic acid, pelargonic acid, lauric acid, tridecanoic acid and so on. The fatty acids cited above are saturated monobasic acids and widely occur in nature in the form of binding with glycerol, higher fatty alcohol, etc., in animal or vegetable oil or wax, thus being readily available from them. The repellent is used in the form of a preparation such as wettable dust, emulsion, powder, granules or fine dust which is obtained by combining an above-cited fatty acid with appropriate carriers and additives. Or a sheet, for example, is impregnated with a solution containing the active ingredient and dried, then the product is used as a packaging material or it is applied to a part of package.

摘要： NEW MATERIAL:3-Hydroxy-7,8-dehydro-beta-ionone of the formula. USE:A tobacco flavor improver. PREPARATION:Leaves of Burley tobacco is extracted with dichloromethane, the extract is subjected to steam distillation to collect the volatile neutral fraction by a usual method. The neutral fraction is subjected to silica-gel column chromatography, then to preparative gas chromatography to isolate the compound of the formula. Or 3-hydroxy-7,8-dehydro-beta-ionol is oxidized to give the compound of the formula. The product is light-yellow oil having flower-like smell containing tobacco-like odor, thus being suitable for use as a tobacco flavor improver.

摘要： NEW MATERIAL:The compound of formulaI. USE:A flavor and taste improving agent for tobacco. PROCESS:Silver nitrate is added to lolioride and alpha-acetoboromoglucose solution in methylene chloride, and stirred in a dark place for 2 days. After filtration, the resultant filtrate is evaporated under reduced pressure to rmove the methylene chloride. The remaining oily residue is then fractionated by the silica gel chromatography. A fraction eluted by a solution of ethyl acetate and hexane at a weight ratio of 4:6 is collected by the high-speed liquid chromatography to give lolioride glucoside tetraacetate expressed by formula II (Ac is acetyl). The resultant compound is then deacetylated by methanol saturated with ammonia, and freeze-dried to give the compound expressed by formulaI.
