Abstract

En fremgangsmåte for syntese av 2-etylantraklnon omfatter dekomponering av et 2-(4'-etylbenzoyl )- benzosyre:nHF:mBF3-kompleks for å oppnå 1 det vesent- lig fullstendig fjerning av HF og BF3. Det gjenværende faststoff krystalliseres 1 konsentrert svovelsyre eller 1 oleum til uren 2-etylantraklnon, EAQ. Denne EAQ renses i en vandig, basisk oppløsning og ved "suhllmerlng" for å oppnå en EAQ med en renhet som er tilstrekkelig for kjent videre anvendelse ved syntese av hydrogenperoksyd.A process for the synthesis of 2-ethyl anthraconone involves decomposition of a 2- (4'-ethylbenzoyl) benzoic acid: nHF: mBF3 complex to achieve substantially complete removal of HF and BF3. The residual solid is crystallized in 1 concentrated sulfuric acid or 1 oleum to impure 2-ethyl anthraconone, EAQ. This EAQ is purified in an aqueous, basic solution and by "mixing" to obtain an EAQ of a purity sufficient for known further use in the synthesis of hydrogen peroxide.
