Usage

General Description

2,6-Dimethyl-3-acetyl-4H-pyran-4-one, also known as maltol, is a naturally occurring organic compound with a pleasant caramel-like odor and flavor. It is commonly found in roasted malt, coffee, cocoa, and bread, and is often used as a flavor enhancer and fragrance ingredient. Maltol has antioxidant properties and is used in the food industry as a flavoring agent in various products such as desserts, candies, and beverages. It is also used in the pharmaceutical industry as a flavoring additive in oral medications and as a fragrance ingredient in cosmetic and personal care products. Maltol is considered safe for consumption and is approved for use in food and fragrance applications by regulatory agencies.

Interaction of acetonitrile with trifluoromethanesulfonic acid: Unexpected formation of a wide variety of structures

Interaction of acetonitrile with trifluoromethanesulfonic acid has been studied by multinuclear NMR and ESI-MS. It has been found that the interaction results in formation of a great variety of different cations and neutral compounds which is controlled by the ratio of CH3CN to TfOH. In the presence of an excess of the acid (molar ratio 1:8-14) diprotonated N-acetylacetamidine 1 is formed as the major product, which eventually transforms into protonated acetamidine 3 and acetic acid 4. At molar ratio of (1:1-2) diprotonated 2,4-dimethyl-6-methylidene-3H-1,3,5-triazine 12, tautomer of the diprotonated trimethyl-s-triazine 11, becomes the main product at an early stage of the reaction and diprotonated 1-(dimethyl-1,3,5-triazin-2-yl) prop-1-en-2-ol 15 at a later stage. In the case of a large excess of acetonitrile (4-20:1) trication 17 is formed as a result of the interaction between 11 and 12 along with some oligomers [(CH3CN) 3]n (n = 4-12).
