process for the production of 5 - nitro - and 6 - nitroderivate of 1,2,3,4 - tetrahydroanthrachinons starting from 1, 2, 3, 4 - tetrahydro - anthracene - 9,10 - diol

摘要

1. A process for the preparation of mononitro derivatives in position 5 or 6 of 1,2,3,4-tetrahydro anthraquinone, in which 1,2,3,4-tetrahydro-9,10-anthracene-diol is subjected to nitration.
