摘要： A method for preparing carboxylic acids including (n+1) carbon atoms, or the related esters, by liquid phase carbonylation of an alcohol including (n) carbon atoms, in the presence of a uniform catalytic system based on at least one iridium compound and at least one halogenated promoter. In particular, the method is characterised in that the content of ester related to said carboxylic acid and alcohol is kept between 15 and 35 % in the medium during the reaction, while the halogenated promoter content is kept between 10 and 20 %, and the partial carbon monoxide pressure is 40-200 bar. Said method enables both the rate of carbonylation and the acetic acid selectivity to be increased.

摘要： A method for preparing carboxylic acids by carbonylating a reagent, particularly an alcohol, in the presence of a rhodium catalyst. According to the method, the liquid phase reaction is carried out in a first zone in the presence of a rhodium catalyst, and the resulting reaction mixture is partially vaporised in a second zone. The vaporised fraction containing the carboxylic acid is later purified and the unvaporised liquid fraction containing the catalyst is recirculated to the first zone. The method is characterised in that said unvaporised fraction is contacted with carbon monoxide in such a way that this compound is not returned to the second zone.

摘要： A method for preparing acetic acid and/or methyl acetate by means of an isomerisation reaction and a carbonylation reaction is disclosed. Specifically, the method for preparing acetic acid and/or methyl acetate comprises reacting reagents that provide formyl radicals and reagents that provide methyl radicals, in the presence of carbon monoxide, water, a solvent and a catalytic system including at least one halogenated promoter and at least one iridium compound. According to the method, a partial carbon monoxide pressure of 0.1.10 Pa to 25.10 Pa is maintained, the amount of reagent providing formyl radicals is maintained at no more than 20 wt % based on the weight of the reaction mixture, and the reagents providing methyl and formyl radicals are supplied in such a way that the molar ratio of the methyl radicals to the formyl radicals is greater than 1. The method is particularly useful for preparing acetic acid and/or methyl acetate from mixtures of methanol and methyl formate.
