| | PRIMULINE Usage And Synthesis |
| Preparation | p-Methylaniline (2 Moore) and sulfur (4.5 atomic ratio) in 200 ~ 280 ℃ heat, with hair smoke from the sulphonated sulfuric acid alkali primrose spirit. | | Properties and Applications | green light yellow. Soluble in water for light yellow, with a light blue fluorescence. The strong sulfuric acid for light yellow, a green fluorescent, after diluted orange yellow precipitation. The dye solution to join strong hydrochloric acid has golden precipitation; Add thick sodium hydroxide solution for orange brown precipitation. Used for the cellulose fibre, silk dyeing, leather and biological shading. Silk dyeing in acetic acid bath, dyeing copper and iron ion in colored light basic unchanged.
