The specification HG/T 30005-2012 covers production safety for disperse navy blue H-GL, the disperse dye indexed as C.I. Disperse Blue 79. It concerns the route that starts from reducing substances, ethylene oxide, acetic acid, 2,4-dinitro-6-bromoaniline, nitrosylsulfuric acid, sulfuric acid and peregal O and runs through hydroxylation, esterification, renitration, coupling and pressure treatment.
