Description:
Iso-butyric acid not important. Use and n-butyric acid is similar, mainly used to produce the corresponding esters, such as methyl iso have apricot, isobutyric acid ester pineapple flavor, isoamyl isobutyrate banana flavor, isobutyl, octyl grapes taste, iso-butyric acid benzyl ester has strawberry flavor jasmine flavor, etc., may be used as synthetic flavors and solvents. Also for the manufacture of varnishes and plasticizers. There are some important differences acid derivative, for the production of industrial real AIBN intermediates, and then converted to the hydrochloride azobis it is insecticide diazinon raw materials.
Usage:
1. Major isobutyrate for synthesis of products, such as methyl isobutyrate, propyl, iso-amyl acetate, benzyl acetate, etc., can be used as food flavors, also used in the pharmaceutical 2.GB 2760-1996 provides for the use of food flavors. Mainly for the preparation of cream, apple, caramel, cheese, bread, yeast and other flavors. 3. isobutyric acid not important. Use and n-butyric acid is similar, mainly used to produce the corresponding esters, such as methyl iso have apricot, isobutyric acid ester pineapple flavor, isoamyl isobutyrate banana flavor, isobutyl, octyl grapes taste, iso-butyric acid benzyl ester has strawberry flavor jasmine flavor, etc., may be used as synthetic flavors and solvents. Also for the manufacture of varnishes and plasticizers. There are some important differences acid derivative, for the production of industrial real AIBN intermediates, and then converted to the hydrochloride azobis it is insecticide diazinon raw materials.
4. The production of raw materials for perfumes and perfume esters for use as textile auxiliaries (in the form of a salt) as a solvent and a variety of chemical reactions.
Brief manufacture process:
Iso-butyric acid and butyric acid preparation method is similar, mainly isobutanol and direct oxidation of isobutyraldehyde, isobutyraldehyde with air or oxygen direct oxidation is a reaction. Other manufacturing methods are: AIBN hydrolysis, methacrylic acid hydrogenation. Methyl-1-nitropropane isobutyric acid oxidation can also get a higher yield. Isobutyric acid can be purified by azeotropic distillation with water, dried over anhydrous isobutyric acid from carbon tetrachloride to give extractive distillation. Acrylic acid ester and at 50 ℃ catalyzed by hydrofluoric acid to produce methyl iso-propyl and iso sour.
