摘要:
A process for the production of acetic acid by the liquid phase carbonylation of an alcohol and/or a reactive derivative thereof in which there is employed a catalyst comprising a complex of rhodium or iridium with a pincer ligand.
摘要:
Process for the production of acetic acid and dimethyl ether by contacting methanol and methyl acetate with a catalyst composition at a temperature in the range 140 to 250 ° C. The catalyst composition contains a zeolite having a 2-dimensional channel system comprising at least one channel which has a 10-membered ring.
摘要:
Process for the carbonylation of a carbonylatable reactant selected from at least one of dimethyl ether and methanol, by carbonylating the carbonylatable reactant with carbon monoxide in the presence of a catalyst to produce a carbonylation product selected from at least one of methyl acetate and acetic acid. The catalyst is formed by compositing a mordenite loaded with at least one of silver and copper, with an inorganic oxide binder.
摘要:
Process for the manufacture of methyl acetate by carbonylating a carbonylatable reactant selected from dimethyl ether and dimethyl carbonate containing less than 2.5 wt % water with carbon monoxide in the presence of a mordenite catalyst. The mordenite has been ion-exchanged with at least one Group IB metal, and the molar ratio of the Group IB metal to total aluminum present in the mordenite is in the range 5 to 50 mol %.
摘要:
A process for the carbonylation of dimethyl ether, dimethyl carbonate and/or methanol with carbon monoxide and hydrogen in the presence of a mordenite catalyst to produce at least one of acetic acid and methyl acetate in which process the mordenite catalyst is regenerated in-situ by contacting the catalyst with a regenerating gas comprising a molecular oxygen-containing gas and an inert diluent at a total pressure in the range 1 to 100 bar and wherein the partial pressure of the molecular oxygen-containing gas is such that the temperature of the catalyst is maintained within the range 225 to 325° C.
摘要:
A process for the manufacture of methyl acetate by the carbonylation of dimethyl ether or dimethyl carbonate with carbon monoxide under substantially anhydrous conditions in the presence of a Group TB metal loaded mordenite catalyst prepared by ion-exchanging mordenite with at least one Group IB metal, the ion-exchanged mordenite having a molar ratio of the Group IB metal to total aluminium present in the mordenite in the range 5 to 50 mol %.
摘要:
Process for preparing a carboxylic acid and/or ester thereof by carbonylating an alcohol and/or reactive derivative thereof with carbon monoxide in the presence of a silver loaded mordenite catalyst.
摘要:
Process for preparing methyl acetate and/or acetic acid by contacting a carbonylatable reactant selected from dimethyl ether and methanol with carbon monoxide in the presence of a catalyst. The catalyst is a H-mordenite bound with a mesoporous binder selected from silicas, aluminas, silica-aluminas, magnesium silicates and magnesium aluminum silicates.
