FIELD: chemical industry, production of terephtalic acid. SUBSTANCE: oxygen or oxygen beneficated gas is used during terephtalic acid production in reaction system, that allows to decrease connected with it danger of fire. Method allows to reduce consumption of reactant and solvent in conjunction with formation of decreased amounts of undesirable by-products, decreased costs connected with processing of waste gasses and decreased pollution of environment as compared with the fact, that takes place during usual process of terephtalic acid production based on air usage. EFFECT: improved process, decreased its costs, improved ecological conditions of process. |
