Chemical Properties
Dark red uniform powder. Easily soluble in water is bright red. The color and luster remain unchanged under high temperature (120℃), the color and luster change slightly when encountering copper ions, and the color and luster remain unchanged when encountering iron ions. Stable color and light in pH=2-6 range, good level-dyeing property, color and light remain unchanged when dyeing with sulfuric acid or formic acid. Fastness to sunlight 6 levels. Compatibility value K=4.
Uses
C.I. Basic red 14 is an alkaline dye that can be removed from aqueous solutions in intermittent adsorption systems using tree ferns as biosorbents.
Preparation
1,3,3-Trimethyl-2-methyleneindoline and 3-((4-Formylphenyl)(methyl)amino)propanenitrilecondensation, and then into chloride.
Properties and Applications
red. Dark red powder. 40 ℃ in the water when the solubility of 40 g/L, a colourful red in the water. The strong sulfuric acid for green light yellow, diluted into a red light yellow. With fluorescent dye acrylic colourful red. Tungsten light in a little dark. In 120 ℃ high temperature dyeing, colour and lustre is unchanged. Dyeing copper ions in colour and lustre micro have change, encounter iron ion colour and lustre is unchanged. Mainly used in acrylic fiber, fiber scattered and article of wool terylen dyeing. Can be used for two vinegar fiber and modified polyester direct printing.
