The reactivities of dyes with ozone were in the following order, Acid Blue 74>disodium 1-(2-hydroxyphenylazo)-2-naphthol-3,6-disulfonate>Direct Yellow 12>Acid Orange 7>disodium 1-phenylazonaphthalene-3,6-disulfonate-2,2′-diolatocopper(II)>Mordant Red 3>Basic Green 4. The reaction of disodium 1-phenyl-azonaphthalene-3,6-disulfonate-2,2′-diolatocopper(II) with ozone was retarded by the introduction of electron-withdrawing groups and 8-sulfonato group. The potassium sulfonate dye was less reactive than the sodium one. Ozonization of l-phenylazonaphthalene-2,2′-diolatocopper(II) gave phenol, 2-naphthol, and phthalic anhydride.
染料与臭氧的反应活性依次为:酸性蓝 74>1-(2-羟基苯基偶氮)-2-萘酚-3,6-二磺酸钠>直接黄 12>酸性橙 7>1-苯基偶氮萘-3,6-二磺酸钠-2,2′-二茂铁铜(II)>媒染红 3>碱性绿 4。在 1-苯基-3,6-萘二磺酸钠-2,2′-二茂铁铜(II)与臭氧的反应中,引入了缩电子基团和 8-磺酸基团,从而延缓了反应的进行。磺酸钾染料的反应性低于磺酸钠染料。臭氧氧化 l-苯基-2,2′-二茂萘铜(II)会产生苯酚、2-萘酚和邻苯二甲酸酐。
