Title:
PROCESS FOR PRODUCING ACETIC ACID
Document Type and Number:
WIPO Patent Application WO/1996/033965
Kind Code:
A1
Abstract:
A process for producing acetic acid by reacting methanol, methyl acetate and the like with carbon monoxide continuously in the presence of a group 8 metal catalyst, methyl iodide and water, wherein water is added to the first distillation column to maintain the state of liquid separation at a decanter on top of the column. It is possible to produce acetic acid with a high quality unattainable heretobefore while reducing the energy of purification.
