Abstract

Postupak ovog pronalaska obezbedjuje poboljšanje ranijeg postupka karbonizacije metanola koje značajno smanjuje proizvodnju karbonilnih nečistoća. Proizvodnja karbonilnih nečistoća, posebno acetaldehida, krotonaldehida, i 2-etil krotonaldehida, u reakcijama karbonizacije metanola je otkriveno da se smanjuje održavanjem metil jodida na oko 5 mas% ili manje u reakcionom medijumu za vreme toka reakcije.[The method of the present invention provides an improvement over prior art methanol carbonylation methods which substantially reduces the production of carbonyl impurities. The production of carbonyl impurities, particularly acetaldehyde, crotonaldehyde, and 2- ethyl crotonaldehyde, in methanol carbonylation reactions has been found to decrease by maintaining about 5 wt % or less methyl iodide in the reaction medium during the course of the reaction.
