ACID BLUE 41 CAS #2666-17-3

Acid Blue 41, molecular weight is 487.46000, density is 1.542g/cm³. Its molecular formula is C₂₃H₁₈N₃NaO₆S, exact mass is 487.08100, PSA (polarizable surface area) is 158.08000, logP (logarithm of oil-water partition coefficient) is 4.40960.
Appearance is dark purple powder. It needs to be stored in a sealed, cool, dry warehouse. It is stable at room temperature and pressure, and should avoid contact with strong oxidants.
Acid Blue 41 can be used for dyeing wool, nylon, silk and wool blended fabrics, and can also be directly printed on wool, silk and nylon fabrics. It has a large strength and good levelness, and is suitable for dyeing medium-depth blue or for color matching.

ACID BLUE 41 Usage And Synthesis
Chemical Properties purple to dark violet powder
Preparation 1-Amino-4-bromo-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid and?N-(4-aminophenyl)-N-methylacetamide in copper salt and tied the presence of acid agents condensation, and then into sodium salt.
Properties and Applications blue. Dark blue powder, soluble in water, water solution without gathered at room temperature phenomenon. The strong sulfuric acid dyes for dark brown, after dilute for pink; In the nitric acid for brown (already break). The water solution is blue, add hydrochloric acid sodium hydroxide or after the same color. Discharge sex is bad, dyeing copper ions in the dark colored, iron ion in light and dark red. Used for wool, polyamide fiber, silk and wool blended fabric dyeing and printing directly, can also be used for leather and paper shading.
