Реферат:
The mechanisms of the reaction between methanol and H2S at 320-500°C in the presence of aluminum oxide that is modified with alkali metal compounds have been studied. L sites and basic sites occur on the surface of the catalysts. The acidity of Al2O3 is reduced with the addition of sodium or potassium hydroxide and carbonate while the basicity is increased compared to an alumopotassium-tungsten catalyst. In terms of their overall activity the hydroxide and carbonate samples are superior to the tungstate sample while in terms of selectivity towards the formation of methanethiol they are inferior to the latter. From a study of the acid-base properties of the catalysts and analysis of the kinetic data, a reaction scheme is proposed that involves the formation of methanethiol via a rapid methoxylation of the surface of the catalyst followed by reaction between the CH3O groups and activated H2S.
