Soluble in water, orange yellow, add hydrochloric acid red and produce precipitation, adding sodium hydroxide solution color unchanged, but the excess after precipitation. Soluble in ethanol, ether, benzene and ethylene glycol ether, acetone-soluble. It is purple in concentrated sulfuric acid, and red precipitate is produced after dilution; It is blue in concentrated nitric acid, and then gradually turns orange. When staining, copper ion color was dark green; When iron ion color was shallower; When chromium ion color changed slightly. |
Use | Acid golden yellow G can be used for wool dyeing and direct printing of wool and silk fabrics, and can also be combined with acid yellow 2G and acid red G to dye golden yellow. Used for soap coloring, but also for paper, leather, paint, medicine, cosmetics, coloring, and for the manufacture of lake pigments. Also used as acid-base indicator (pH = 1-3). Mainly used for the coloring of soap and wool, silk, leather, paper, etc |

Overview | at present, acid Golden G is one of the main varieties of golden dye, acid Golden G is mainly used for dyeing agent, acid-base indicator, for the coloring of soap and silk, wool, paper, leather and other dyeing. |
Application | currently, acridine yellow (soap yellow) is used for paper, soap, coloring of cosmetics (paper coloring gives a good amount of color, but not acid-resistant wool, silk fabric dyeing and printing, leather dyeing. It can also be used as an indicator (pH = 1-3). It can also be used in medicine, organic pigments, paints, wood products and biological coloring. |
