ACID GREEN 3 Chemical Properties,Uses,Production
Chemical Properties
Green powder
Uses
Limited use as a dye for silk and wool fabrics; as biological stain.
Definition
ChEBI: An organic sodium salt having 3-[(ethyl{4-[(4-{ethyl[(3-sulfonatophenyl)methyl]amino}phenyl)(phenyl)methylidene]cyclohexa-2,5-dien-1-ylidene}azaniumyl)methyl]benzene-1-sulfonate. Used as a substitute for Light green SF yellowish in Masson's trichrome, alth ugh it is prone to fade. Previously used as a food dye but is now no longer approved.
Preparation
Benzaldehyde (1 Moore) and 3-(Ethyl(phenyl)amino)methyl)benzenesulfonic acid (2 Moore) condensation, will product oxidation, and then translate into sodium salt.
General Description
A dull dark green powder. Used as a dye for silk or wool and biological stains.
Air & Water Reactions
Very soluble in water. Forms a green solution, which becomes brownish-yellow by addition of HCl, and blackish-green with NaOH.
Reactivity Profile
ACID GREEN 3 neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides.
