Abstract
A qualitative analysis for the ammoximation of acetaldehyde to its oxime in the TS-1(Titanium Silicalite-1)/H2O2 system was investigated using an in situ infrared spectrometer (ReactIR15). NH3 is first oxidized to NH2OH by TS-1/H2O2; then, CH3CH=NOH forms after NH2OH reacts with CH3CHO. That means the intermediate of this reaction is NH2OH instead of CH3CH=NH. Experiments have been conducted to verify the mechanism, and the results are in good agreement with the infrared findings.
Highlights
Acetaldoxime is one of the simplest oxime-containing compounds, and it has a wide variety of uses in chemical synthesis processes as an important intermediate [1,2]
Acetaldehyde and TS‐1 were added to the reactor in accordance with the order of Ammonia, acetaldehyde and TS-1 were addedconditions
ReactIR15, we found that the hydroxylamine concentration was uniformly reduced during filtration
Summary
Acetaldoxime is one of the simplest oxime-containing compounds, and it has a wide variety of uses in chemical synthesis processes as an important intermediate [1,2]. Investigated the correlation between the membrane structure and reaction efficiency; the effects of the conditions on the benzene conversion, product yield, hydrogen conversion and water production rate were examined in detail [15].
