Pigment Green 18 Usage And Synthesis

Chemical Properties

Green crystals. Soluble in water; ethyl, methyl, and amyl alcohol.

Uses

A triphenylmethane dye with fungicidal and limited antiseptic activity. The term Malachine green applies to the oxalate as well as the chloride. Harmful if swallowed. Avoid release to the environment.

Definition

ChEBI: An organic chloride salt that is the monochloride salt of malachite green cation. Used as a green-coloured dye, as a counter-stain in histology, and for its anti-fungal properties in aquaculture.

Preparation

commonly known as Malachite Green. (a) in the presence of hydrochloric acid or sulfuric acid, Benzaldehyde ?(1 Moore) and N,N-dimethylaniline(2 Moore) condensation, and then used lamps and acid oxidation its products; (b) N,N-dimethylaniline and 1-(Trichloromethyl)benzene?heating.

General Description

Green crystals with metallic luster. Water solutions are blue-green. Used in dyeing silk, wool, biological staining, etc.

Air & Water Reactions

Very soluble in water.

Reactivity Profile

Pigment Green 18 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. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Hazard

Toxic by ingestion.

Properties and Applications

bright blue light green. Green belt flash crystallization. Soluble in cold water and hot water are blue-green, easily soluble in ethanol are blue-green. The strong sulfuric acid for yellow, diluted into dark orange; In nitric acid to orange, diluted into orange brown. The dye solution to join sodium hydroxide formation microstrip green white precipitation; Add hydrochloric acid to red light yellow. Used in acrylic, silk, wool, vinegar fiber dyeing, also used in leather, hemp, bamboo, wood, paper, shading, also used in the manufacture color amylum, solvent dye
