Isopentane (C5H12)

Magawo Aumisiri

Isopentane, yomwe imadziwikanso kuti 2-methylbutane, ili ndi mankhwala a C5H12. Ndi madzi opanda utoto, owonekera komanso osasunthika ndi fungo lokoma. Isopentane ndiyotentha kwambiri, ndipo nthunzi ndi mpweya wake zimatha kupanga chisakanizo chophulika; ndikosavuta kuwotcha ndikuphulika ikayatsidwa moto, kutentha kwambiri, ndi ma oxidants, ndikuyaka kuti ipange utsi wokhumudwitsa; imatha kuyankha mwamphamvu ndi ma oxidants ndipo imatha kuyaka. Nkhuni yake imalemera kuposa mpweya ndipo imatha kufalikira patali kwambiri, ndipo imayambitsanso moto ngati lawi lotseguka. Pakakhala kutentha kwambiri, kupanikizika kwamkati kwa chidebe kumakulirakulira ndipo pamakhala chiwopsezo chothana ndi kuphulika. Zinthu zoyaka (zowola) ndi carbon monoxide ndi carbon dioxide. Pentane itha kupezeka kuchokera kukung'ambika kwa othandizira komanso kuwonongeka kwamafuta a gasi kapena mafuta. Amagwiritsidwa ntchito kwambiri pakuphatikizira kwazinthu, itha kugwiritsidwa ntchito ngati chosungunulira chothandizira pakupanga polyethylene, wothandizila wophulika wa polystyrene, wophulitsira makina a polyurethane thovu, chosungunulira deasphalting, ndi zina .; ikagwiritsidwa ntchito ngati chosungunulira, itha kugwiritsidwa ntchito ndi pentane, Alkane, heptane, ndi zina zotere. Izi zili ndi nambala ya octane yambiri ndipo itha kugwiritsidwa ntchito ngati mafuta pamagalimoto ndi ndege. Yosungirako ndi mayendedwe mayendedwe: nyumba yosungiramo ndi mpweya, kutentha otsika ndi youma; kusungidwa mosiyana ndi zowonjezera ndi zidulo. Njira yozimitsira moto: utsire madzi kuti muziziritse chidebecho, ndipo ngati kuli kotheka, chotsani chidebecho pamalo owotchera moto pamalo poyera. Ngati chidebe chomwe chikuwotcha moto chasintha mtundu kapena chimatulutsa mawu kuchokera pachida chachitetezo, ayenera kuchotsedwa nthawi yomweyo. Wozimitsa: thovu, ufa wouma, carbon dioxide, dothi lamchenga. Kuzimitsa ndi madzi sikuthandiza.

Ntchito:

Kuyendetsa makina oyendetsa:

Isopentane imagwiritsidwa ntchito potsekeka pakupanga kwamphamvu yamagetsi kuyendetsa ma turbines.

Kuzizira:

Isopentane imagwiritsidwa ntchito, molumikizana ndi ayezi wouma kapena nayitrogeni wamadzimadzi, kuzizira matupi a cryosectioning mu histology.

OMoto wothandizila:

Itha kusakanikirana ndi cyclopentane ngati chinthu chopopera thobvu la thovu lolimba la urethane.

Phukusi Labwino:

Ubwino:

1.Fakitole yathu imatulutsa Neon kuchokera kuzinthu zopangira zapamwamba, kuphatikiza mtengo wake ndi wotsika mtengo.
2. Neon imapangidwa pambuyo pochulukitsa njira zambiri zoyeretsera ndikukonzanso mu fakitole yathu. Makina olamulira pa intaneti amatsimikizira kuti mpweya ukuyera nthawi iliyonse.
3. Pakudzazidwa, silinda iyenera kuyanika kaye kwa nthawi yayitali (osachepera 16hrs), kenako timatsuka chopukusira, pomaliza timachichotsa ndi gasi woyambirira. Njira zonsezi zimatsimikizira kuti mpweya ndi wosalala.  
4. Takhalapo m'munda wamafuta kwazaka zambiri, zokumana nazo zambiri pakupanga ndi kutumiza kunja tiyeni tipambane kukhulupilira kwa makasitomala, amakhutitsa ndi ntchito yathu ndikutipatsa ndemanga yabwino.
