GENERAL DESCRIPTION AND APPLICATIONS |
||
|
Isovaleric acid ( also called Isopentanoic acid ) is a member of the series of fatty acids of colorless liquid with a penetrating aroma; slightly soluble in water, soluble in alcohol, and ether; boils at 176 C . It is used in flavorings, perfumes, plasticizers and pharmaceuticals. This compound reacts with bases, oxidizing agents and reducing agents. Valeric acid and its derivatives are used as components and intermediates in perfume manufacturing; flavors, ester-type lubricants; plasticizers, pharmaceuticals, vinyl stabilizers. There are almost infinite esters obtained from thousands of potential starting materials. Esters are formed by removal of water from an acid and an alcohol, e.g., carboxylic acid esters, phosphoric acid esters, and sulfonic acid esters. Carboxylic acid esters are used as in a variety of direct and indirect applications. Lower chain esters are used as flavouring base materials, plasticizers, solvent carriers and coupling agents. Higher chain compounds are used as components in metalworking fluids, surfactants, lubricants, detergents, oiling agents, emulsifiers, wetting agents textile treatments and emollients, They are also used as intermediates for the manufacture of a variety of target compounds. The almost infinite esters provide a wide range of viscosity, specific gravity, vapor pressure, boiling point, and other physical and chemical properties for the proper application selections. |
