摘要： A method for reducing aldehydes in an acetic acid production process is disclosed. The acetic acid is produced by reacting methanol and carbon monoxide in the presence of a carbonylation catalyst. The method comprises reacting an aldehyde-containing stream with an alcohol to form an acetal-containing stream. An acetal-enriched stream is separated from the acetal-containing stream and then hydrolyzed to form a hydrolysis mixture comprising the alcohol and the aldehydes. The alcohol is isolated from the hydrolysis mixture and used to react with the aldehyde-containing stream to form the acetal-containing stream. The invention reduces aldehydes in the acetic acid produced.

摘要： A process is disclosed for the production of vinyl acetate where a mixture of ethylene, acetic acid, and oxygen is reacted in the presence of a catalyst to produce a product mixture of vinyl acetate, ethylene, carbon dioxide, acetic acid, water, ethyl acetate, and ethylene glycol diacetate. The product mixture contains both a gaseous phase and a liquid phase, which are separated. The gas phase contains at least carbon dioxide, which is removed via gas stream. The crude vinyl acetate stream is removed via a liquid stream. The crude vinyl acetate is then further separated to isolate a stream containing at the majority of the ethylene glycol diacetate. The ethylene glycol diacetate stream is then methanolyzed in the presence of a methanolyzing catalyst, to recover methyl acetate, which can be optionally recycled as a feed stock to an acetic acid plant.
