아크리딘 C화학적 특성, 용도, 생산
화학적 성질
colourless to light yellow crystals
용도
manufacture of dyes and intermediates; some dyes derived from it are used as antiseptics, e.g. 9-aminoacridine, acriflavine and proflavine. The hydrochloride has been used as reagent for cobalt, iron and zinc.
정의
A colorless
crystalline heterocyclic compound
with three fused rings. Derivatives of acridine
are used as dyes and biological stains.
World Health Organization (WHO)
Acridine derivatives with antiseptic and disinfectant activity,
including acriflavine, proflavine and euflavine, were formerly used in the treatment
of infected wounds and burns. Such use has largely been discontinued on the
grounds that safer and more effective alternatives are now available. Following
demonstration of the mutagenic activity of proflavine in 1978 it was withdrawn from dental products in Denmark. Subsequently, euflavine was similarly withdrawn.
일반 설명
Small colorless needle-like crystalline solid. Slightly soluble in hot water. Slightly denser than water. Contact may irritate skin, eyes, and mucous membranes. Sublimes before melting when heated. May be toxic by ingestion.
공기와 물의 반응
Slightly soluble in hot water.
반응 프로필
Acridine 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. Burns to give toxic oxides of nitrogen.
건강위험
Inhalation irritates respiratory system and causes sneezing, crying, and vomiting. Contact with liquid irritates eyes, skin, and mucous membranes. At high temperature and during sun exposure, damage to the cornea, skin, and mucous membranes may occur following the liberation of Acridine vapor.
Safety Profile
Poison by ingestion, subcutaneous, and intravenous routes. Mutation data reported. A skin, eye, and mucous membrane irritant. When heated to decomposition it emits toxic fumes of NO,.
잠재적 노출
Acridine and its derivatives are widely used in the production of dyestuffs, such as acriflavine, benzoflavine, and chrysaniline; and in the synthesis of pharmaceuticals; such as aurinacrine, proflavine, and rivanol. A constituent of coal tar, coal tar creosote; found in wastes from gas and tar plants and coke oven emissions. Incompatibilities: Strong acids, strong oxidizers.

UN2713 Acridine, Hazard Class: 6.1; Labels: 6.1-Poisonous materials
Purification Methods
Acridine has been crystallised twice from *benzene/cyclohexane, or from aqueous EtOH, then sublimed, removing and discarding the first 25% of the sublimate. The remainder is again crystallised and sublimed, discarding the first 10-15% [Wolf & Anderson J Am Chem Soc 77 1608 1955]. Acridine can also be purified by crystallisation from n-heptane and then from ethanol/water after pre-treatment with activated charcoal, or by chromatography on alumina with pet ether in a darkened room. Alternatively, acridine can be precipitated as the hydrochloride from *benzene solution by adding HCl, after which the base is regenerated, dried at 110o/50mm, and recrystallised to constant melting point from pet ether [Cumper et al. J Chem Soc 4518 1962]. The regenerated free base may be recrystallised, chromatographed on basic alumina, then vacuum-sublimed and zone-refined. [Williams & Clarke, J Chem Soc, Faraday Trans 1 73 514 1977, Albert, The Acridines Arnold Press 1966.] It can exist in five crystalline forms and is steam volatile. It is a strong IRRITANT to skin and mucous membranes and can become a chronic irritant— handle it with CARE. [Beilstein 20/8 V 199.]
