摘要： A process as provided for producing an acetic acid process stream having less than 400 ppm propionic acid and less than 1500 ppm water. Methanol or a reactive derivative thereof and carbon monoxide is fed to a carbonylation reactor in which there is maintained during the course of the process a liquid reaction composition containing an iridium carbonylation catalyst, methyl iodide co-catalyst, a promoter, water at a concentration of less than about 8% by weight, methyl acetate, acetic acid, and propionic acid by-product and its precursors. Liquid reaction composition is withdrawn from the carbonylation reactor and introduced to a flash zone to form a vapor fraction comprising water, acetic acid product, propionic acid by-product, methyl acetate, methyl iodide and propionic acid precursors, and a liquid fraction comprising involatile iridium catalyst, involatile optional promoter or promoters, acetic acid and water. The liquid fraction is recycled from the flash zone to the carbonylation reactor and introduced into a first distillation zone where a light ends recycle stream is removed and recycled to the carbonylation reactor, A process stream is removed from the first distillation zone comprising acetic acid, propionic acid by-product and less than 1500 ppm water. If the process stream comprises greater than 400 ppm propionic acid, the process stream is introduced into a second distillation zone where propionic acid by-product is removed together with an acetic acid process stream containing less than 400 ppm propionic acid and less than 1500 ppm water.

摘要： Catalyst particles are contacted with a liquid and a gas in a vertically extending cylindrical vessel. The particles and liquid are placed in the vessel into which the gas and liquid are continuously fed from the bottom thereof so that an upwardly flowing mixture comprising the particles, liquid and gas is formed. The mixture is introduced into a gas separating zone disposed adjacent to an upper portion of the vessel to separate the mixture by gravity into a gas phase, a supernatant liquid phase and a phase rich in the catalyst particles. The gas and supernatant phases are continuously withdrawn from the separating zone while the catalyst particles-rich phase is continuously recycled to the bottom of the vessel by gravity.

摘要： A method for preparing carboxylic acids by carbonylating a reagent, particularly an alcohol, in the presence of an iridium catalyst. According to the method, the liquid phase reaction is carried out in a first zone in the presence of an iridium 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： In a process for producing acetic anhydride and acetic acid by reacting methanol and methyl acetate, optionally together with dimethyl ether, with carbon monoxide, acetic anhydride and acetic acid are effectively produced with the use of a sequence of production facilities by carrying out separation of low-boiling point fraction mainly consisting of methyl iodide, methyl acetate and dimethyl ether with the use of at least two distillation zones, separating catalyst drops entrained from the vapor-liquid separation zone in at least one distillation zone and further by controlling the pressurization of the vapor-liquid separation zone and the above distillation zones under 5 bar to a pressure greater than atmospheric pressure. The invention not only reduces the facility cost and the energy cost to be borne for separation, but also improves the capability of recovering low-boiling point fractions and further recovers the entrained catalyst, so that acetic anhydride and acetic acid can efficiently be produced with the use of a sequence of production facilities.
