Chemical properties:
Colorless oily liquid with irritating and unpleasant odor. Miscible with water, ethanol and ether.
Uses
1. Used to determine the critical temperature and surface tension of fat dissolution, to eliminate the influence of iron when measuring copper by electrolysis, and also used as an extractant and decalcifying agent
2. Used to prepare spices, medicines and other organic chemicals, and also used for leather deashing. Butyric acid is a food flavoring allowed by my country’s regulations, and is often used to enhance the flavor of butter, cheese and fruit flavors. The dosage is based on normal production needs, generally 82mg/kg in candy; 60-270mg/kg in chewing gum; 32mg/kg in baked goods; 18rag/kg in margarine; 6.5mg/kg in cold drinks.
3. The main use of butyric acid is to make cellulose butyrate, which is used to make thermoformed signs, glasses, car steering wheels, black telephone parts, etc. It is stronger than cellulose acetate in terms of anti-aging, water resistance, shrinkage, etc. Butyric acid is also widely used in the manufacture of varnish and molding powder. Butyric acid is used to make cellulose acetate. It can be mixed with a variety of resins and is mostly used for paint, spinning and cotton blending. Butyric acid is used to synthesize various butyric acid esters, cellulose flame retardants and other organic synthesis. The main derivatives are butyric acid formate, ethyl butyrate, α-bromobutyric acid, butyramide, butyrylanilide, butyryl chloride, butyric acid triglyceride, butyrylaminophenylethyl ether, butyrylaminoanisidine, etc. It is used in spices, food additives, medicine, flame retardants, mildew inhibitors, etc. Butyric acid esters have a pleasant fruity aroma, such as methyl butyrate has an apple aroma, ethyl butyrate has a pineapple aroma, isoamyl butyrate has a snow pear aroma, and isopropyl butyrate also has a pineapple aroma. Linalyl butyrate and geranyl butyrate in daily flavors are also derivatives of butyric acid. Although butyric acid is a malodorous substance and its use is restricted, it is also an indispensable substance for flavoring raw materials. It can not only be used as a raw material for the main seasoning of butter and cheese flavors, but also can enhance the flavor and thicken many fruit flavors. When used as a flavoring agent, a very small amount of butyric acid can emit a very strong and thick smell.
4. As a feed preservative and electrolyte balancer. It is also a food flavoring allowed by my country’s regulations, and is often used to enhance the flavor of butter, cheese and fruit flavors. Uses: An important fine chemical raw material for the synthesis of cellulose butyrate and butyrate esters. Its esters are widely used in spices, instrument additives, medicine and other fields. Uses: To determine the critical temperature of fat dissolution. Determination of surface tension. When determining copper by electrolysis, it is used to eliminate the influence of iron.
