Isobutyric acid

Isobutyric acid is a colorless, volatile liquid with a pungent, rancid odor, melting at –47 °C and boiling at 155 °C. It is a branched-chain aliphatic carboxylic acid and classified as an organic chemical intermediate. Its primary industrial use is as a precursor in the synthesis of esters—particularly isobutyl esters—for fragrances, flavorings, and plasticizers. It also serves as a building block in the production of herbicides (e.g., propanil derivatives), pharmaceuticals (e.g., certain anti-inflammatory agents), and specialty polymers. Typical application areas include agrochemicals, fine chemicals, food additives, and coatings.

1. Isobutyric acid is mainly used in the synthesis of isobutyric acid esters, such as methyl isobutyrate, propyl ester, isoamyl ester and benzyl ester. It can also be used as edible flavor and used in pharmaceutical.2. GB 2760-1996 provides for isobutyric acid as the food flavors allowed to use. It is mainly used for the preparation of butter, apple, caramel, cheese, bread, yeast and other flavors.3. Isobutyric acid is not more important than butyric acid, but has the similar uses with n-butyric acid. Isobutyric acid is mainly used to produce the corresponding esters, such as methyl isobutyrate with apricot incense, propyl isobutyrate with pineapple flavor, isobutyl isobutyrate with banana flavor, octyl isobutyrate with grapes taste, benzyl isobutyrate with jasmine smell, etc. It can be used for preparing flavors and solvents and also used in the manufacture of varnishes and plasticizers. Isobutyric acid has some important derivatives that, in the industry, is actually used for the production of isobutyronitrile intermediates, and then converted to isobutylamidine hydrochloride that is the raw materials of pesticide diazinon.4. Used for the raw materials of perfume and perfume ester, and also used as the solvents of textile auxiliaries (in the form of salt) and a variety of chemical reactions.
Colorless oily liquid; strong irritating odor; miscible with water; soluble in alcohol, ether and so on.
