- Taste modifiers
-
A method of modifying the taste of a consumable, comprising adding to a consumable base at least one compound of the formula I in which (a) A is selected from the moieties (b) n is from 0-7, such that X is absent or a linear alkylene group in which n is from 1-7; and (c) Z is absent and Y is a moiety selected from the groups —CHO, or —CH2OH; or (d) Z is present and is a C1-7 linear alkane, and Y is selected from —CHOH, —CO, or —COC(CH3)O. The result is a consumable with enhanced mouthfeel and/or creaminess.

- Reactions of Dioxiranes with Selected Oleochemicals
-
Reaction of fatty acids with dimethyldioxirane in acetone produces ketoacids in 9-12percent yields in which the ketone carbonyl is distributed along the fatty chain.The n-1 position appears to be preferred.Lactones of hydroxy fatty acids are oxidized by this reagent, but in low yields, to the corresponding ketoacids.Biphasic epoxidations with methylethyldioxirane in 2-butanone were conducted with methyl oleate and methyl ricinoleate to give the corresponding epoxides in high yield, and olive oil and tallow were cleanly epoxidized by this procedure as well.KEY WORDS: Chain functionalization, dioxirane, epoxidation, oleic acid, ricinoleic acid, tallow.

- OZONOLYSIS OF ALKENES AND REACTIONS OF POLYFUNCTIONAL COMPOUNDS. XVIII. INVESTIGATION OF A NEW OZONOLYTIC SYNTHESIS OF CARBOXYLIC ACIDS
-
By identification of the 18O isotope label in the oligomeric peroxide obtained by ozonization of a cyclic olefin in the presence of heavy oxygen and also in the product from catalytic isomerization of this peroxide ( the α,ο-dicarboxylic acids or its dimethyl ester ) it was shown that oxygen enters the ozonolysis product when the reaction is carried out in ether solvents.It is suggested that the increased content of active oxygen in the ozonolysis peroxy product is due to oxidation of the ether solvent to form α-hydroperoxide and addition of the latter to the oligomeric zwitterion, solvated by the polar solvents.It was established that the catalytic and thermal isomerization of the oligomeric peroxides and ozonides of cyclic olefins to the α,ο-dicarboxylic acids and ο-formyl carboxylic acids occurs through the oligomeric α-hydroxy peresters and α-hydroxy esters respectively.
