| abstract | The essence of the invention: extraction with ethyl acetate of untreated production water for the production of maleic or phthalic anhydride, washing the extract with water, combining aqueous fractions which are treated with activated carbon at a weight ratio of maleic acid: ethyl acetate: water: coal equal to 1: 2.0-8, 2: 2.3-4.5: 0.005-0.015, followed by isomerization of an aqueous solution of maleic acid using UV irradiation in the presence of sodium bromide and chlorine or using thiourea. |
