    摘要: An improved process for oxidizing an amine to the corresponding amine oxide with peracetic acid comprises carrying out the reaction in a distillation column, using as oxidant the gaseous mixture of peracetic acid and acetaldehyde resulting from the vapor-phase oxidation of acetaldehyde with oxygen. The amine is introduced in liquid form into the upper portion of the distillation column while the gaseous mixture of peracetic acid and acetaldehyde is simultaneously introduced into an intermediate location in the column. Reaction takes place within the column, with acetic acid and acetaldehyde being withdrawn as vapor from the top while a liquid comprising the amine oxide product is recovered from the base.
