Physical and Chemical Properties | Red Lotus with gray powder. Very soluble in water, ethanol, also soluble in ethylene glycol ether. The aqueous solution is pink with fluorescence, and sodium hydroxide is added to turn blue pink. The dye was yellow pink in concentrated sulfuric acid, and turned blue pink after dilution; Apricot yellow in concentrated nitric acid. |

Use | The cationic pink FF is suitable for dyeing silk, cotton, acetate, nylon and acrylic fibers. But the light fastness is poor, also used for leather and paper coloring. |
production method | with ω-aldehyde as raw material, it was mixed with sodium formate in acetic anhydride, the product is obtained by condensation reaction in the presence of magnesium oxide. The product is poured into water to precipitate the dye. The final product was obtained by filtration, drying and pulverization.. |
