| Use | is mainly used as a priming agent for cotton fabric dyeing and printing, also can be used as fast pigment intermediates phenol AS-RL is mainly used for cotton dyeing red priming agent, also used for dyeing vinylon, viscose fiber, silk, acetate fiber and used for cotton printing. The affinity to cotton was moderate, the coupling ability was moderate, and its performance was similar to that of phenol AS-OL (C.I.37530). |
| production method | with 2,3-acid and p-methoxyaniline as raw materials, first of all, the 3-acid is prepared as a sodium salt and then condensed with P-methoxyaniline in the presence of PCl3, neutralized, distilled, filtered and dried to give a finished product.. |
