Description: Isobutyric acid, also known as 2-methylpropanoic acid, It is found in the free state in carobs (Ceratonia siliqua), in vanilla and in the root of Arnica dulcis, and as an ethyl ester in croton oil. Isobutyric acid is an isomer of n-butyric acid; they have the same chemical formula C4H8O2 but a different structure. Usage: 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. |
