Acid Yellow 127 Chemical Properties,Uses,Production

Preparation

2,4-Diaminobenzenesulfonic acid first and 2,4,6-Trichloro-1,3,5-triazine condensation, again with N-methylbenzenamine condensation, and then diazo, and 1-(2-Chlorophenyl)-3-methyl-1H-pyrazol-5(4H)-onecoupling.

Properties and Applications

colourful green light yellow. Yellow powder, soluble in water. The strong sulfuric acid for yellow, diluted still is yellow, accompanied by precipitation; In strong hydrochloric acid for yellow, diluted unchanged; In the nitric acid is yellow, diluted and precipitation for tender yellow; In the thick of sodium hydroxide solution of decomposition, after diluted yellow precipitation. The dye solution for green light light yellow, boil can get clear solution. Used for wool, silk, polyamide fiber fabric dyeing and printing directly, can also be used for leather color.
