Acid Green 25 Chemical Properties,Uses,Production

Chemical Properties

dark green powder

Uses

For nylon sutures: Fed. Regist. 42, 52395 (1977). Permitted for use in drugs and cosmetics, excluding use in eye area: ibid. 47, 49628 (1982).

Preparation

(a) ?anthracene-1,4,9,10-tetraol?or 1,4-Dihydroxyanthracene-9,10-dione and anthracene-1,4,9,10-tetraol?mixture?with 2 moles of p-Methylaniline in the presence of boric acid condensation; (b) 1,4-Dichloroanthracene-9,10-dione and 2 Moore’s p-Methylaniline?condensation, its product (C.I. Solvent Green 3, C.I. 61565) products, and translate into sodium salt.

General Description

Fine black or green powder.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

Acid Green 25 is incompatible with strong oxidizing agents. .

Fire Hazard

Flash point data for Acid Green 25 are not available. Acid Green 25 is probably combustible.

Safety Profile

Moderately toxic by ingestion. Askin and severe eye irritant.
When heated to decomposition it emits very toxic fumesof NOx, SOx, and Na2O.

Purification Methods

Purify it by salting out three times from an aqueous solution with sodium acetate, followed by repeated extraction with EtOH [McGrew & Schneider J Am Chem Soc 72 2547 1950]. It is a green powder that is slightly soluble in Me2CO, EtOH and pyridine. It is soluble in conc H2SO4 to give a blue solution that becomes turquoise on dilution. [Allen et al. J Org Chem 7 63 1942, Beilstein 14 H 725.]
