| titleOfInvention | Method (versions) and systems for producing isophthalic acid and terephthalic acid |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to an improved method of converting a raw material stream containing at least one C8 aromatic compound, ortho-xylene, meta-xylene, para-xylene and ethylbenzene, into at least one product stream containing isophthalic acid and terephthalic acid (IPA/TA), which comprises the following steps: a) removing ethylbenzene from said raw material stream to form a raw material stream poor in ethylbenzene; b) removing ortho-xylene from said ethylbenzene-poor raw material stream to form a raw material stream poor in ortho-xylene, containing meta-xylene and para-xylene; c) oxidising said ortho-xylene-poor raw material stream to form a product stream containing IPA/TA in ratio of 0.5% to 99.5% IPA and 0.5% to 99.5% TA; d) drying said product stream in a drier to remove residual solvent and water; e) removing the substantially purified IPA/TA product stream; f) dissolving said product stream; and g) separating said IPA and said TA from said dissolved product stream. n EFFECT: method enables to obtain optimum amounts of IPA and TA from a raw material stream containing at least one C8 aromatic compound, in order to optimise output of IPA and TA. n 7 cl, 4 dwg |
