3. Ethanol + Ammonia + Sulfuric Acid The most widely used method is the passing of ammonia and ethanol over a catalyst such as alumina or silica (Schweizer et al 1978). Diethylamine can be separated from the mixture by selective distillations and extractions. ...
sulfuric acid. The acidic phase was adjusted to pH 9 and re-extracted with heptane–isoamyl alcohol, and the organic phase was evaporated to dryness. The residue was dissolved in the mobile phase (aqueous 60% acetonitrile) and subjected to high-performance liquid chromatography on a column (15...
This results in the formation of the methyl ester of 4-(4-acetaminophenyl)-butyric acid (30.2.1.4). This is treated with an alkali in order to hydrolyze both the amide and ester parts of the molecule, which forms 4-(4-aminophenyl)butyric acid (30.2.1.5), which upon reaction with ...
