DISPERSE RED 19 Usage And Synthesis
Chemical Properties
dark purple to dark red-brown crystalline powder
Uses
DR19 can be used as red side groups in an NLO polyester for potential application in optical switching devices. It can also be bonded with polyurethane to form stable films, which may be used in the fabrication of analog systems.
Preparation
4-Nitrobenzenamine diazo, and N,N-dihydroxyethylaniline?coupling.
General Description
Disperse Red 19 (DR19) is widely used as a non-linear optical (NLO) dye with two hydroxyl (OH) groups, which can covalently connect with the base polymer. It can be linked as a side chain group that provides thermal and photo stability to the polymeric unit.
Properties and Applications
Yellow?red .red powder. Soluble in ethanol, acetone and benzene. The strong sulfuric acid for yellow, diluted for brown; In strong hydrochloric acid for red, and then into a brown. Used for polyester, vinegar fiber, three vinegar fiber, polyamide, acrylic and their blended fabric dyeing, also used for sheep and plastic shading, hue for yellow light red.
