Mawu Oyamba

Pentane. Makhalidwe ake ndi awa:

Zimasakanikirana ndi zosungunulira zambiri za organic koma osati ndi madzi.

Chemical Properties: N-pentane ndi aliphatic hydrocarbon yomwe imatha kuyaka ndipo imakhala ndi malo otsika komanso kutentha kwa autoignition. Ikhoza kuwotchedwa mumlengalenga kuti ipange carbon dioxide ndi madzi. Mapangidwe ake ndi osavuta, ndipo n-pentane imagwira ntchito ndi mankhwala omwe amapezeka kwambiri.

Ntchito: N-pentane imagwiritsidwa ntchito kwambiri poyesera mankhwala, kukonzekera zosungunulira ndi zosakaniza zosungunulira, komanso ndizofunikira kwambiri pamakampani a petroleum.

Njira yokonzekera: n-pentane imapezeka makamaka mwa kusweka ndi kukonzanso mu ndondomeko yoyenga mafuta. Mafuta a petroleum omwe amapangidwa ndi njirazi ali ndi n-pentane, yomwe imatha kupatulidwa ndi kuyeretsedwa ndi distillation kuti ipeze n-pentane yoyera.

Chidziwitso chachitetezo: n-pentane ndi madzi omwe amatha kuyaka ndipo amayenera kusungidwa kutali ndi malawi otseguka komanso kutentha kwambiri. Iyenera kugwiritsidwa ntchito pamalo abwino mpweya wabwino ndi kupewa kukhudzana ndi amphamvu oxidizing mankhwala. Kuwonekera kwa n-pentane kwa nthawi yaitali kungayambitse khungu louma komanso lopweteka, ndipo njira zotetezera zoyenera monga magolovesi ndi magalasi ziyenera kutengedwa. Mukapuma mwangozi kapena kukhudzana ndi khungu ndi n-pentane, funsani thandizo lachipatala mwamsanga.
