CAS: 213-46-7|Picene

Kev piav qhia

Picene（CAS: 213-46-7）yog hydrocarbon pom nyob rau hauv pitchy residue tau nyob rau hauv distillation ntawm peat tar thiab roj av. Qhov no yog distilled rau dryness thiab lub distillate rov recrystallized los ntawm cymene. Nws tuaj yeem raug npaj los ntawm kev ua ntawm anhydrous aluminium chloride ntawm kev sib xyaw ntawm naphthalene thiab 1, 2-dibromoethane, lossis los ntawm distilling a-dinaphthhostilbene. Nws crystallizes nyob rau hauv loj tsis muaj xim daim hlau uas muaj ib tug xiav fluorescence. Nws yog soluble nyob rau hauv concentrated sulfuric acid nrog ib tug ntsuab xim. Chromic acid nyob rau hauv glacial acetic acid daws oxidizes nws mus rau picene-quinone, picene-quinone carboxylic acid, thiab thaum kawg mus phthalic acid.

Thaum intercalated nrog poov tshuaj los yog rubidium thiab txias kom qis dua 18 K, picene tau tshaj tawm tias muaj cov khoom siv hluav taws xob superconductive. Txawm li cas los xij, vim qhov tsis muaj peev xwm los tsim cov hauj lwm no, qhov ua tau zoo tshaj plaws ntawm doped picene tau ntsib nrog hnyav scepticism.
