4-溴丁酸乙脂 - Reference Information
| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| introduction | ethyl 4-bromobutyrate is a carboxylate derivative, colorless and transparent to yellow liquid, which can be used as pesticide and pharmaceutical intermediate, and can be used in laboratory research and development process and chemical production process. |
| Application | 1-aminoanthraquinone is an organic compound that can be used as an analytical reagent and also used in organic synthesis; it can also be used to prepare dispersion, activity, Intermediate of vat dyes. |
| Use | Used as pesticide and pharmaceutical intermediate |
| production method | 1. preparation method: 200g(2.33mol) of γ-butyrolactone (2), 375mL of absolute ethanol are added to a reaction bottle equipped with a stirrer, a thermometer and a ventilation catheter, cold to 0 ℃ in an ice salt bath, and dry hydrogen bromide gas is introduced until the reactants do not change, which takes about 2 hours. Place at 0 ℃ for 24 hours. The reactant is poured into 1L of cold water, and after full stirring, the organic layer is separated, and the water layer is extracted with bromoethane twice, 10mL each time. The organic layers were combined, the ethanol was washed with 2% potassium hydroxide solution, dilute hydrochloric acid and water, and anhydrous sodium sulfate was dried. After the solvent was recovered, the fraction was fractionated under reduced pressure, and the fraction of 97~99 ℃/3.3kPa was collected to obtain 350~380g of γ-bromobutyrate (1) with a yield of 77% ~ 84%.
