| titleOfInvention | Method of producing hydroxytetralones from dihydroxynaphthalenes |
| abstract | FIELD: chemistry. n SUBSTANCE: present invention relates to the method of obtaining isomer 5-, 6- and 7-hydroxy-1-tetralones, as well as 6- and 7-hydroxy-2-tetralones through selective ion hydrogenation with alkanes of corresponding dihydroxynaphthalenes, which can be used in chemical, pharmaceutical and other industries. The process is carried out in the presence of aluminium chloride, containing up to 5% water impurities, using excess alkane at temperature 100-150°C. Aluminium chloride is used in molar excess of between 2.5 and 5 relative the initial dihydroxynaphthalene. n EFFECT: simple method of producing hydroxytetralone. n 5 cl, 3 ex, 1 tbl |
