| titleOfInvention | Method for preparing first-grade amide from aldoxime or formaldehyde and hydroxylamine |
| abstract | The invention provides a method for preparing first-grade amide from aldoxime or formaldehyde and hydroxylamine. According to the method, alkalis such as CsOH, KOH, and NaOH are used as catalysts to be heated in an organic solvent, water or a mixed solvent of an organic solvent and water under the air condition without nitrogen protection; simple, mild and green rearrangement reaction of the aldoxime or direct condensation and rearrangement reaction of the formaldehyde and hydroxylamine hydrochloride can be realized through the method for the synthesis of a series of first-grade amides. The raw material aldoxime used by the method provided by the invention can be conveniently prepared through a laboratory method or an industrial method, and the formaldehyde, the hydroxylamine hydrochloride and the alkali catalysts can be obtained by direct purchase. Compared with other methods reported in documents, the alkali catalysts used by the method disclosed by the invention are simple, low in price and small in toxicity, do not need to be prepared, and belong to water soluble catalysts; and in addition, the reaction is pretty mild in conditions, can be carried out in air, is easy to operate, and can also use the mixed solvent of the organic solvent and the water. The method is very low in requirements on the reaction conditions, and has certain application prospect. |
