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.
