Химические свойства

slightly beige crystals

Использование

Adamantane is mainly used for the synthesis of medicine to treat influenza, serve as NMDA receptor channel blockers. Also be used for preparation of advanced lubricants, photographic material, surface active agents, catalysts and other products.

Определение

adamantane: A colourless crystallinehydrocarbon C₁₀H₁₆; m.p.269°C. It is found in certain petroleumfractions. The structure containsthree symmetrically fusedcyclohexane rings.

Методы очистки

Crystallise adamantane from acetone or cyclohexane, and sublime it in a vacuum below its melting point [Butler et al. J Chem Soc, Faraday Trans I 82 535 1986]. Adamantane is also purified by dissolving it in n-heptane (ca 10mL/g of adamantane) on a hot plate, adding activated charcoal (2g/100g of adamantane), and boiling for 30minutes, filtering the hot solution through a filter paper, concentrating the filtrate until crystallisation just starts, adding one quarter of the original volume of n-heptane, and allowing to cool slowly over a period of hours. The supernatant is decanted off and the crystals are dried in vacuo at 25o. [Prelog & Seiwerth Chem Ber 74 1769 1941, Schleyer et al. Org Synth Coll Vol V 16 1973, Walter et al. J Am Chem Soc 107 793 1985.] [Beilstein 5 III 393, 5 IV 469.]
