| use | GB 2760-1996 specified as allowed food spices. the product can dissolve oil, wax, rosin, nitrocellulose, cellulose acetate, cellulose ether, etc., and is used as a solvent for paints and films, as well as for artificial leather, spices and organic synthesis. Used as a standard substance and solvent for chromatographic analysis, and also used in perfume manufacturing and organic synthesis |
| production method | obtained by esterification of butanol and formic acid. Formic acid and butanol were heated and refluxed for 24h. After cooling, wash with saturated sodium chloride solution, saturated sodium bicarbonate solution, and then wash with saturated sodium chloride solution. Dry with anhydrous sodium sulfate, distilled, and collect the 106-107 ℃ fraction to obtain the finished product with 74% yield. The esterification reaction can also be carried out in the presence of sulfuric acid. It is obtained by azeotropic distillation of formic acid, n-butanol and isopropyl formate. |
