Usage

Uses

Basic blue 3 has a brilliant blue shade and thus has been used as a colorant in dyeing acrylic fabrics.

Preparation

3-(Diethylamino)phenol or N,N-diethyl-3-methoxybenzenamine?nitrosation, then the product with hydrochloride between 3-(Diethylamino)phenol condensation.

General Description

Basic blue 3 (BB3) can be removed from aqueous solutions with the help of activated carbon prepared from rubber seed coat.

Properties and Applications

colourful green light blue. Bronze powder. In 20 ℃ water solubility of 40 g/L, solubility effected by temperature is very small, water solution is green light blue. The strong sulfuric acid for wine, diluted into a red light blue. In aqueous solution of sodium hydroxide to join a blue-black precipitation. For green light blue dye acrylic colourful, tungsten light in more green. In 120 ℃ high temperature dyeing, color is green. Copper ions in dyeing color shade significant turn green in colour and lustre of iron ion in the dark. Compatibility value is 3.5, the f value is 0.31. For wool/nitriles, stick/acrylic blended fabric graft copolymerization dyeing, also can be used for direct printing acrylic carpet.
