use | red ITR is mainly used for dyeing cotton, but also for dyeing viscose fiber, silk, nylon and printing cotton cloth. It is AS-ITR with chromophenol and dyed brilliant red. The coupling ability is medium and the coupling speed is slow. It can replace soluble reduction of rosin IR and large red base. |
Production method | Using N-acetyl o-methoxyaniline as raw material, first undergo chlorosulfonation reaction with chlorosulfonic acid, and then with diethylamine Hydrolysis, and finally alkaline hydrolysis to obtain the product.. |
