APPLICATIONS |
||
| n-Butyric acid is a saturated four-carbon carboxylic acid which is a clear liquid, with a suffocating odor and with melting point -6 C and boiling point 164 C. It occurs naturally in rancid butter, in much animal fat and in plant oil. It is soluble in water, ethanol and ether. It can be obtained by the fermentation of sugar or starch, brought about by the addition calcium carbonate or by the oxidation of butanol in the presence of potassium permanganate. There is a structural formula called isobutyric acid which can not be obtained by the fermentation but by the oxidation of isopropyl alcohol with potassium bichromate and sulfuric acid. Isobutyric acid melts at -47 C and boils at 154 C. It is slightly soluble in water but soluble in ethanol, ether and organic solvents. Butyric acid is a strong acid and reacts with bases, strong oxidants and metals. It is used to eliminate calcium in leather industry. Butyric acid family products, such as their esters, are used for the production of plastics, plasticizers, surfactants and textile auxiliaries. They are used in food additives, flavorings, varnishes, perfumes, pharmaceuticals and disinfectants. | ||
