	Preparation of ionones - Patent 4565894
		Ionones are prepared by cyclization of pseudoionone with concentrated sulfuric acid in the presence of an organic solvent or diluent, while cooling, and by dilution of the reaction mixture with water, by a continuous process in which the pseudoionone is combined with an aliphatic or cycloaliphatic hydrocarbon which boils at 25.degree.-65.degree.
		A process for the continuous preparation of ionones by cyclization of pseudoionone with concentrated sulfuric acid in the presence of an organic solvent or diluent, while cooling, and by dilution of the reaction mixture with water, wherein the pseudoionone is combined with an aliphatic or cycloaliphatic hydrocarbon which boils at 25.degree.-65.degree.
		The results obtained are surprising since it is emphasized in virtually all of the conventional methods that good yields of ionones, in particular of.beta.-ionone, are obtained in the cyclization of pseudoionone with sulfuric acid only when the process is carried out at very low temperatures.

	Sweet and Powdery Fragrance Ingredients: Ionones :: Bois de Jasmin
		While the ionones range from a scent that is reminiscent of violets in full bloom to an aroma of soft wood overlaid with violet sweetness, the methyl ionones are stronger, with a more pronounced orris and wood tonality.
		The role of methyl ionone in the floral-oriental genre represented by fragrances such as Coty L’Origan (1905) and Guerlain L’Heure Bleue (1912) is undoubtedly important, given its ability to round out the notes and lend a sweet softness to the floral accords.
		The violet facet of Trésor’s apricot and rose marriage is enhanced by pairing of Iso E Super with methyl ionone, and the finished result is the epitome of a sweet, soft, and gently powdery fragrance.

	CCM/Market Reports-/Beta Ionone Production & Market in China
		In China, ionone & methyl ionone are either made from natural citral, which comes from litsea cubeba oil, or made from synthetic citral, which is imported from overseas.
		The import and export quantity of beta ionone in 2002 is 250MTs and 12MTs, respectively.
		This kinds of ionone is made from synthetic citral.

		No adverse effects were observed as judged (in comparison with controls) by appearance, growth, haematological and blood chemical determinations, terminal body weight, organ weights, or gross and microscopic examination of major organs (Oser et al., 1965).
		Groups of 10 male and 10 female rats were maintained for 17 weeks on diets containing "Ionone Standard" (60% alpha-ionone and 40% ß-ionone) at levels of 0, 1000, 2500, and 10 000 ppm (approximately equivalent to 50, 125, and 500 mg/kg bw).
		No adverse effects were observed on growth, appearance, food intake, haematology, final body weights, organ weights, or macroscopic appearance of organs of rats on all levels of "Ionone Standard" in the diet.

	Ingredient: Ionone Beta
		Ionone Beta has a particularly intense freesia character.
		The volume of Ionone Beta is emphasized by a fruity, somewhat raspberry-like background.
		Ionone Beta Extra, Code N° 0011893, is similar to the regular quality but has a slight olfactive nuance and increased substantivity.

		Interestingly, the isomer of ß-ionone, a-ionone, did not show such trend, and was perceived at the same level for all the panelists.
		Another compound, also found in many fruit, ß-damascenone, was perceived 700 times higher for some panelists when it was tested in orange juice, but there were no such differences when it was tested in water.
		There were no such differences for a-ionone, a constitutional isomer of ß-ionone.

	Solvated electrons in electrolytes
		Minimization of the free energy F gives nonlinear equations, which have localized solutions.
		This suggests an idea of a new type of self-localized states in on electrolyte ionone, when the electron is self-trapped by a cloud of surrounding ions (Fig.1a and Fig.1b).
		The screening of solvated electrons in electrolytes produces an experimentally observed effect: as the ion concentration increases, the solvated electron absorption band shifts to the blue side.

	Molecule of the Day : Ionone (You're turning violet, Violet!)
		Being one of the first people to synthesize an odorant that simulates something from Nature must have felt absolutely magical.
		Check out the entry on violet (which mentions ionones) at Indieperfumes, a site I hadn't seen before today.
		International Flavors and Fragrances (a catalog in which you can spend quite some time; see also Flavornet) describes it as "Woody, Dry, Fruity, Raspberry." I love reading commercial fragrance materials - they read like serious chemical catalogs with structures, flashpoint, molecular weight, and the like...

	CIPO - Patent - 1053688
		Mild, floral-woody, somewhat oily-herbaceous odor, remotely reminiscent of Rose with similarity to the odor of hydrogenated Ionones.
		More fruity than really floral, but not as tenacious as the Ionone.
		Suggested for use in perfume compositions, but since it does not offer any new or unusual odor characteristics, and it cannot be produced in economical competition to betaIonone, there is little or no chance that it will ever become a standard shelf ingredient for the perfumer.
