Method for preparing acetic acid ACETIC ACID and / or Khlayat bromide METHYL ACAETATE by Alazmrt ISOMERIZATION and introducing a carbonyl group CARBONYLATION

摘要

Abstract: the invention relates to a preparation of acetic acid and methyl acetate and / or acetic acid methyl acetate using simultaneous interactions Llazmrt and carbonylation carbonyl group.The reaction mixture contains a substance detector and at least one provides the roots of Fwrmyl formyl radicals and detecting material, and at least one provides the roots of methyl methyl radicals, together with water. The second part is at a maximum. 5% by weight, and carbon monoxide under a partial pressure of 0, Ytrawhbyn1 u00d7 25 u00d7 10 Pa, 10 Pa Pa Pa, solvent, and catalytic system containing a Mhljn halogenated one of at least one compound at least the iridium based iridium.In a typical interaction, Azmrt isomerized methyl formate methyl formate composition, acid - acetic acid according to interact HCOO CH3 u2192 CH3 COOH and the methanol nrethanol for carbonyl group carbonylation The formation of acid - acetic acid according to interact CH3 OH + CO u2192 article is maintained CH3 COOH reagents that provide formyl radicals formula1 roots at or the weight of the reaction mixture, while less than 20% Molecular ratioThe roots of methyl radicals bromide to the root of the formula1 formyl radicals in mixture is greater than one.
