     Beispiel B :   Wird an Stelle von   Antbrachinon   2-Methylanthrachinon verwendet, so geht die Reduktion ganz ähnlich vor sich. Man erhält ebenfalls eine gelbe alkalische Lösung, aus welcher   Methyl- und Azetylderivate,   in analoger Weise wie beim Anthrachinon gewonnen werden können. Die erhaltenen Produkte zeigen wenig Neigung zum krystallisieren.

     Example B: If 2-methylanthraquinone is used instead of antrachinone, the reduction proceeds in a very similar manner. A yellow alkaline solution is also obtained, from which methyl and acetyl derivatives can be obtained in a manner analogous to that for anthraquinone. The products obtained show little tendency to crystallize.
