摘要： A process for recovering Group VIII noble metals from tar is provided. The process involves heating a mixture of the Group VIII noble metal, tar and methyl iodide in a closed system at a temperature in excess of 50°C. During the process the Group VIII noble metal is precipitated in an insoluble form which can be separated by e.g. filtration. Precipitation preferably takes place at a temperature in the range 120 to 180°C. The process is particularly suitable for the recovery of either rhodium or iridium.

摘要： The solubility and stability of rhodium catalysts in rhodium-catalysed carbonylation of alkyl esters or alkyl ethers under substantially anhydrous conditions to produce carboxylic acid anhydrides is improved by the use of co-promoters selected from the group:
1,3-dialkyl-4-methylimidazolium iodide;
1,3-dialkyl-4-ethylimidazolium iodide;
1,3-dialkyl-4-n-propylimidazolium iodide;
1,3-dialkyl-4-isopropylimidazolium iodide;
1,3-dialkyl-4-n-butylimidazolium iodide
1,3-dialkyl-4-sec-butylimidazolium iodide
1,3-dialkyl-4-tert-butylimidazolium iodide;
1,3-dialkyl-2,4,5-trimethylimidazolium iodide and mixtures thereof where the alkyl groups are independently C₁ to C₂₀ alkyl.摘要翻译： 通过使用选自以下的助催化剂，改善了铑催化剂在基本无水条件下铑催化羰基化烷基酯或烷基醚以产生羧酸酐的溶解度和稳定性：1,3-二烷基-4-甲基咪唑 碘; 碘化1,3-二烷基-4-乙基咪唑鎓; 1,3-二烷基-4-正丙基咪唑碘化物; 碘化1,3-二烷基-4-异丙基咪唑鎓; 1,3-二烷基-4-正丁基咪唑碘化物碘化1,3-二烷基-4-仲丁基咪唑碘化物1,3-二烷基-4-叔丁基咪唑碘化物; 1,3-二烷基-2,4,5-三甲基咪唑碘化物及其混合物，其中烷基独立地为C 1至C 20烷基。

摘要： A process for separating a mixture comprising methyl iodide, methyl acetate and optionally acetone is provided. The process comprises an extractive countercurrent distillation using acetic acid as the extractant in which an upward flow of the mixture in vapour flow is contacted with a downward flow of liquid acetic acid. The process is suitably carried out in a distillation column having between 20 and 60 plates.
