| Hazard Information | Back Directory | [Uses]
3-Hydroxy-N-2-naphthyl-2-naphthamide is mainly used as a base agent for dyeing and printing cotton fibers (cotton fabrics). It is a commonly used base agent for dyeing cotton yarn red or brown and can be used as a substitute for Naphthol AS. It is also used for dyeing vinylon, viscose fiber, silk, and nylon; it can be coupled with bright red base RC and red base KB to dye bright red, coupled with blue salt to dye blue, and coupled with black base or black salt to dye black. | [Preparation]
Naphthalen-2-amine and 3-Hydroxy-2-naphthoic acid condensation. | [Properties and Applications]
yellowish powder, soluble point 243 ~ 244 ℃. Insoluble in water solution and sodium carbonate, soluble in chlorobenzene, in the solution for hydrogen oxide yellow liquid. To the stability of the air is good. Mainly used for cotton, cotton yarn line, bath towel dyeing, also can be used to PVA, viscose, silk and polyamide fiber dyeing, general is not used for printing. This product to cotton affinity is higher, coupled ability medium. |
