Bright brown powder

Uses

Basic Blue 7100 (CAS# 2390-60-5) is a dye with antimicrobial properties. Basic Blue 7100 is a toxic substance with a toxicologial screening value of 0.0025 ug/kg body weight per day. Dyes and metabolites, Environmental Testing

Preparation

Bis(4-(diethylamino)phenyl)methanone and N-Ethylnaphthalen-1-amine in toluene in different amine chlorine presence of phosphorus condensation.

Properties and Applications

colourful red blue light. Flash brown cream content. Slightly soluble in cold water, soluble in hot water for blue, easily soluble in ethanol to blue. The strong sulfuric acid is palm in light yellow, diluted red for yellow; In nitric acid for olive green. The dye solution to join sodium hydroxide for red brown. The thing in cotton dyeing, drop 10% of sulfuric acid into a light yellow brown; Drops of 10% sodium hydroxide solution become red light yellow; Drop acid solution red yellow ferrie sulfate-potassium thiosulfate change. Used for silk, wool, cotton cloth tannins mordant dyeing of dyeing, also can be used in the manufacture of oil, carbon, ball pen wax paper, bamboo and wood light color. Also used in the manufacture of color pigments and solvent dye deposit.
