THE low temperature polymer of acetaldehyde was first described by Travers1 and Letort2. The structure suggested for it by Staudinger3 was a chain: The formation of this polymer has been further investigated by Letort and Duval4, but so far little positive evidence has been given for ...
In ethanol, NH2OH's transformation into NH4+ involves the oxidation of acetaldehyde as a consequence. While in CH3CN, CuII oxidizes NH2OH, yielding N2O and [Cu(CH3CN)4]+. The solvent-dependent reaction's mechanistic route is identified and substantiated through the synthesized integration of ...

Adsorption isotherms for acetaldehyde, propionaldehyde, and butyraldehyde on Davison molecular sieve 13X were determined gravimetrically at three temperatures. The isoteric heat of adsorption of acetaldehyde and propionaldehyde decreased initially with the increase in loading, then increased up to a ...
