Disperse Red 221 Usage And Synthesis
Preparation4-Hydroxy-naphthalene-1,8-dicarboxylic anhydride and 3-Methoxypropan-1-amine?condensation, and diazo the M-chloroaniline?coupling.
Properties and ApplicationsYellow light red powder. In dye in bath of iron, calcium, magnesium ions on color shade without the influence, a slight change of copper ions. Dyeing appropriate pH value for 4 ~ 6, dyeing and printing alkali not when. The dyes as bright red yellow light, suitable for indonesians;, the fastness is compatible, sublimation fastness is better, the levelness general. Carrier dyeing, performance is poor, the melt method suitable for temperature, should not be more than 220 ℃. Dye two vinegar fine performance is a bit poor, three vinegar fiber is fair. Not suitable for the polyamide fiber dyeing, in the dyeing performance on fiber is a bit poor. Can’t be printing the impression of the discharge.
