| Questions And Answer | Back Directory | [Application]
2-Methylhexanoic acid, also known as 2-butylpropionic acid, butylmethylacetic acid, or hexane-2-carboxylic acid, is FEMA number 3191. It is a colorless, oily liquid at room temperature. Its optically active isomers are miscible with water, ether, ethanol, chloroform, and other solvents. It is naturally found in apples and strawberries. Aroma: Acidic, oily, fatty, lard, and chicken fat aroma, with hints of roasted, appetizing dishes. Taste: Dairy, creamy, and oily fatty aroma. Used in food processing flavorings such as lard, chicken fat, appetizing dishes, and dairy products. It can be produced by chlorinating sec-hexanol to form a Grignard reagent, then passing dry carbon dioxide gas into the Grignard reagent reaction solution, reacting, and finally hydrolyzing to obtain the product. |
