Heptane: Chomera Chofunika Kwambiri cha Alkane

Heptane ndi alkane yodziwika bwino yolunjika yokhala ndi formula ya mankhwala C₇H₁₆, yomwe imapanga kapangidwe kokhazikika ka mankhwala kudzera mu ma bond amodzi olumikiza ma atomu asanu ndi awiri a kaboni ndi ma atomu khumi ndi asanu ndi limodzi a hydrogen.
Ponena za makhalidwe ake enieni, heptane ndi madzi opanda mtundu komanso owonekera bwino omwe ali ndi fungo lapadera lochepa. Kutentha kwake ndi pafupifupi madigiri 98.4 Celsius, kutentha kwake ndi -90.6 Celsius, ndipo kuchuluka kwake ndi kochepa kuposa madzi, pafupifupi magalamu 0.684 pa sentimita imodzi pa madigiri 20 Celsius. Heptane sisungunuka m'madzi koma imasungunuka mosavuta mu zinthu zachilengedwe monga ethanol ndi ether.
Monga mankhwala ofunikira kwambiri, heptane imagwiritsidwa ntchito mosiyanasiyana m'ma laboratories ndi mafakitale. Nthawi zambiri imagwiritsidwa ntchito ngati organic solvent kusungunula zinthu monga mafuta, rabara, ndi utomoni; pofufuza mankhwala, heptane ingagwiritsidwe ntchito ngati chinthu chokhazikika choyezera zida ndikutsimikizira kulondola kwa njira zowunikira.
Tiyenera kudziwa kuti heptane imatha kuyaka, ndipo nthunzi yake imatha kupanga chisakanizo chophulika ndi mpweya, chomwe chimakhala chosavuta kuyaka ndi kuphulika chikayikidwa pa malawi otseguka komanso kutentha kwambiri. Chifukwa chake, pakusunga ndi kugwiritsa ntchito, ndikofunikira kupewa magwero a moto ndi magwero a kutentha, kusunga mpweya wabwino, ndikuchita njira zoyenera zopewera moto ndi kuphulika kuti zitsimikizire chitetezo.
