Abstract: The invention relates to a method for producing a catalyst for cracking organic carbon compounds, said method comprising the following steps: a) producing an aqueous suspension comprising red mud and at least one calcium salt, b) heating the suspension to a temperature between 25° C. and 78° C., and c) removing at least most part of an aqueous phase from a solid product mixture produced in step b), said solid product mixture comprising the catalyst. The invention further relates to a catalyst and to a method for cracking organic carbon compounds.

Abstract: The invention relates to a method for transesterification of at least one component comprising at least one ester group with at least one component comprising at least one hydroxyl group, wherein the red mud produced in the Bayer process used for producing aluminum is added to the method as a reaction-promoting component. The invention also relates to the use of carboxylic acid salts produced during the transesterification method as plant treating agents and as detergents in cleaning and washing agents. The invention also relates to the use of dealkalized red mud obtained by means of the method according to the invention as the iron-contributing component of an iron fertilizer which can be used in particular in agriculture and to which limestone can also be added.

Abstract: The invention relates to a process for alkaline hydrolysis of carboxylic acid derivatives, especially carboxylic esters, to carboxylic acids, wherein, for the alkaline hydrolysis of the carboxylic acid derivatives, red mud which is produced by the Bayer process used for aluminum production is used as a reaction-promoting component, especially as a hydroxide ion source.
