production method
Acetaldoxime is derived from the reaction of hydroxylamine and acetaldehyde aqueous solution. Reaction equation: CH3CHO+NH2OH·HCl+NaOH→CH3CH=NOH+NaCl+H2O In current industrial production, crystalline hydroxylamine sulfate with a higher content is generally used as raw material, and then it is formulated into 20%-50% during use The aqueous solution then reacts with acetaldehyde to produce acetaldoxime. The reaction equation is such as: CH3CHO+(NH2OH)2·H2SO4→CH3CH=NOH. Add acetaldehyde to the above hydroxylamine sulfate aqueous solution, react at 40～50℃ for 2h, and remove the inorganic salt after cooling to obtain about 50% of acetaldoxime. After testing, the amount of impurities in the aqueous solution is very small except for acetaldoxime and water, and the yield of acetaldoxime is also more than 90% (calculated as hydroxylamine sulfate). This aqueous solution is extracted and refined , You can get acetaldoxime products with a content of more than 90%.
use
1. After melting, it is used as a good solvent for many inorganic and organic compounds, organic synthesis, stability, plasticizer, alcohol denaturant.
2. Aldoxime one-pot method to generate amide. In the presence of the catalyst InCl3, acetaldoxime replaces water and hydrates with nitriles to form amides, and the yield is high
