Abstract

Procedure for preparing semicarbazone of β naphthoquinone, by reaction of semicarbazide hydrochloride on β naphthoquinone, characterized by reacting an aqueous solution of semicarbazide hydrochloride on a boiling ethanolic solution of β naphthoquinone, the amounts of water and ethanol being in the presence, in the reaction mixture such that the volumetric water: ethanol ratio is around 40: 100 to 360: 100.
