By the reaction of phenylisothiocyanate, halogen-, nitrobenzoyl isothiocyanates with 1,2-dioxanthraquinone (alizarin) and 1,2,5,8-tetrahydroxyanthraquinone (quinalizarin) in pyridine at 90-100 °C for 5 hours, the corresponding derivatives phenyl(benzoyl) thiocarbamates were obtained. The dyeing properties of synthesized compounds were studied. The property of dye in 1,2-0,0-bis (para-chlorobenzoylthiocarbamоyl) alizarin has been revealed and this compound is used as a dye of toilet soap with antiseptic action.
