실험 절차

Known in the present-day practice is a method of producing the bisulfite compound of 2-fluorenonyl-glyoxal, said method consisting in that fluorene is acylated by acetic anhydride in the presence of aluminum chloride to obtain 2-acetylfluorene at a yield of 60 weight percent. Then the thus-obtained 2-acetylfluorene is oxidized by sodium bichromate in an acetic-acid medium at 70°-75° C during 6 hours and 2-acetylfluorenon is isolated at a yield of 50 weight percent.
