Process for the production of methyl acetate by carbonylating dimethyl ether with carbon monoxide in the presence of hydrogen and a zeolite catalyst. The process is carried out with a molar ratio of hydrogen to carbon monoxide of at least 1 and the catalyst has been calcined at a temperature of from about 375&#xb0; C. to about 475&#xb0; C.

Carbonylation process

Process for producing alkene(s) from an oxygenate feedstock in a reactor by dehydration in the presence of a supported heteropolyacid catalyst. The pore volume of the supported heteropolyacid catalyst satisfies the following formula:0.6&#x2212;0.3[loading/Surface Area of Dried Catalyst]where;

Process for producing alkenes oxygenates by using supported heteropolyacid catalysts

Process for the manufacture of at least one of acetic acid and methyl acetate by carbonylating at least one carbonylatable reactant selected from methanol, dimethyl ether and dimethyl carbonate with carbon monoxide in the presence of a zeolite of structure type MOR. The zeolite has greater than 50% of its crystals in the size range to 3 microns.

Carbonylation process for the production of acetic acid and/or methyl acetate

This invention relates to a novel catalyst composition comprising a heteropolyacid and a siliceous support which is in the form of extrudates or pellets and to a process for hydrating olefins to the corresponding alcohols in the vapour phase in the presence of such a catalyst composition. By using the specific catalyst composition described herein it is possible not only to increase the space-time-yield of a process but also to prolong the life thereof thereby reducing the frequency with which the catalyst is changed or replaced on a plant, especially in an olefin hydration process.

Olefin hydration process and catalyst

This invention relates to a method for the hydration of olefins to the corresponding alcohols in the presence of a catalyst system comprising phosphoric acid catalyst supported on a siliceous support. One of the features of the invention is the use of a support which has a high crush strength, a high porosity and low metallic impurities. Using such a support, the catalyst system and the reaction conditions specified not only increase the life of the catalyst system by preventing loss of the crush strength of the support but also the improve the space-time-yield of the alcohol produced.
