3-Ethoxybenzenamine - Reference Information
| Chemical properties | colorless oily liquid. Boiling point 248 ℃,167-169 ℃(12.93kPa),127-128 ℃(1.47kPa), relative density 1.032, refractive index 1.5655. Soluble in alcohol and ether, slightly soluble in water, light and air into a brown yellow. |
| Use | for organic synthesis. |
| production method | from M-aminophenol by acetylation, alkylation, hydrolysis, neutralization. 1. Acetylation M-aminophenol was added to acetic acid and heated to reflux for 8H. After the acetic acid was recovered, the mixture was water-separated, cooled, and then filtered to obtain acetaminophen ([621-42-1]). 2. Alkylation ethanol, sodium hydroxide, M-acetaminophen and bromoethane were added into the reactor, heated and refluxed for 8H, poured into water, cooled and filtered to obtain m-acetamidophenyl ether. 3. Hydrolysis, neutralization M-acetamidophenylether was mixed with industrial hydrochloric acid, heated in a water bath for 8H, then poured into water and neutralized to alkalinity with 40% sodium hydroxide. The oil layer was separated. The aqueous solution was extracted with ether, and the ether was recovered and then distilled under reduced pressure together with the oil layer. Under the protection of nitrogen, a fraction of 140-144 ° C. (2.0kPa), I .e., M-ethoxyaniline, was collected. |
