Mainly used for the preparation of apple, pear, banana and cream flavor. occasionally used for cosmetics flavor, mainly with its fruit flavor in lipstick flavor, or as a modifier in the new flavor. A large number of food essences such as pineapple, banana, apple, pear, Berry, nuts, peach, alcohol, etc. butyl butyrate is a kind of edible flavor that is allowed to be used by our country. It is commonly used in the preparation of banana, pineapple, apple and other fruit flavor, as well as the flavor of the cream flavor. Dosage according to the normal production needs, generally in the chewing gum usage is about 150 ~ 1500mg/kg; Candy in 24 mg/kg; Cold drink in 22 mg/kg; Baked food in 22 mg/kg; 8.6mg/kg in beverage. used in organic synthesis, as solvent and fragrance. Butyl butyrate as a solvent, applied to nitrocellulose, shellac, coumarone resin and coatings; Used as spices is mainly modified with apple, pineapple and other flavors. used as chromatographic analysis standard substance and solvent, also used in organic synthesis mainly used in the preparation of daily food flavor, but also in the manufacture of paint, solvent for resin and nitrocellulose organic synthesis. Fragrance preparation. Solvent. Used in organic synthesis, as a solvent and fragrance. |
| production method | is obtained by esterification of butyric acid and butanol. Butyric acid, butanol and a small amount of sulfuric acid were added into the reaction Pan, heated and refluxed for about 4-5H, then neutralized with alkali, washed, and fractionated under reduced pressure to collect 112 ℃(14.6kPa) fractions to obtain the finished product. n-butyl butyrate is naturally found in bananas, strawberries, apples, grapes, etc. It is produced industrially by esterification of butyric acid with butanol under sulfuric acid catalysis. Butyric acid, butanol and a small amount of concentrated sulfuric acid were added to the reaction kettle, heated to reflux for 4-5H, cooled and washed with water; Then neutralized with 5% Na2C03 solution, and then washed with water to neutral. 1kg of anhydrous calcium chloride was added, dried, filtered and distilled, and the fraction at 112 ° C. (14.6kPa) was collected to obtain butyl butyrate. C3H7COOH + C4H9OH[H2SO4]→ C3H7COOC4H9 + H2O is made by heating n-butanol to 400 ° C. Vapor through manganese dioxide or zinc oxide. N-butanol was obtained by passing CuO-VO at 180-200 °c. It is refined by esterification of butyric acid and butanol under the catalysis of sulfuric acid. |
