khalidwe
Zamadzimadzi zopanda mtundu. Insoluble m'madzi, sungunuka mu mowa, miscible mu ether, chloroform. Mpweya wake umapanga chisakanizo chophulika ndi mpweya, zomwe zimayambitsa kuyaka ndi kuphulika ngati lawi lotseguka ndi mphamvu ya kutentha kwakukulu. Imatha kuchitapo kanthu mwamphamvu ndi okosijeni.
Njira
The mafakitale-grade n-heptane akhoza kuyeretsedwa ndi concentrated sulfuric acid kutsuka, methanol azeotropic distillation ndi njira zina.
ntchito
Imagwiritsidwa ntchito ngati reagent yowunikira, muyeso woyeserera wa injini ya petulo, chinthu chowunikira pakuwunika kwa chromatographic, ndi zosungunulira. Amagwiritsidwa ntchito ngati mulingo wotsimikizira nambala ya octane, ndipo angagwiritsidwenso ntchito ngati choledzeretsa, zosungunulira komanso zopangira za organic synthesis.
chitetezo
mbewa mtsempha jekeseni LD50: 222mg/kg; mbewa anakoka mpweya 2h LCso: 75000mg/m3. Mankhwalawa amawononga chilengedwe, amatha kuwononga matupi amadzi ndi mlengalenga, ndipo bioaccumulates muunyolo wofunikira wa chakudya cha anthu, makamaka nsomba. Heptane ingayambitse chizungulire, nseru, anorexia, kuyenda modabwitsa, ngakhale kukomoka ndi kukomoka. Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino. Kutengeka kwambiri ndi moto. Khalani kutali ndi gwero la moto ndi kutentha. Kutentha kwa nyumba yosungiramo zinthu sikuyenera kupitirira 30 ° C. Dzitetezeni ku dzuwa. Sungani chidebecho chosindikizidwa mwamphamvu. Iyenera kusungidwa mosiyana ndi oxidizing wothandizira.
