Abstract:  Conditions have been found for the determination of some phenoxazones by titanometric coulometry using platinum electrode to generate Ti(III) ions, while the point of equivalency was recorded potentiometrically. It has been found, that correct and accurate results can be obtained when the amount of ethanol in the coulometric vessel is within 2—7 ml and the amount of the substance determined is 0.2—0,6 mg in 50—100 ml. Acetone was found a suitable solvent in the determination of 9-diethylaminobenzo[a]phenoxaz-5-one.
