Synthesis and properties of reactive dyes, derivatives of 3,10-bis(3aminopropylamino)-6,13-dichlorotriphenodioxazin-4,11-disulphonic acid

2-Chloro-5-nitrobenzenesulphonic-1 acid, 1,3-propylenediamine, chloranil and cyanuric chloride were used as raw materials to synthesise several reactive dyes, derivatives of 6,13-dichlorotriphenodioxazine. Spectroscopic and application properties of the dyes were determined.
