FIELD: chemistry.
SUBSTANCE: invention relates to an improved method for alkaline hydrolysis of carboxylic acid derivatives to carboxylic acids, where for hydrolysis of carboxylic acid derivatives, red mud formed during production of aluminium via a Bayer process is used as a reaction accelerating component. The invention is suitable for hydrolysis of all carboxylic acid derivatives. The method also enables comprehensive recycling of red mud, owing to which further economic and environmental advantages are provided.
EFFECT: effective reduction of the cost of the method.
