Mawu Oyamba
Heptanal. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha heptanaldehyde:
Ubwino:
1. Maonekedwe: Heptanal ndi madzi opanda mtundu okhala ndi fungo lapadera.
2. Kachulukidwe: Heptanal imakhala ndi kachulukidwe kakang'ono, pafupifupi 0.82 g/cm³.
4. Kusungunuka: Heptanal imasungunuka mu mowa ndi ether solvents, koma pafupifupi osasungunuka m'madzi.
Gwiritsani ntchito:
1. Heptanaldehyde ndi yofunika kwambiri yapakatikati, yomwe ingagwiritsidwe ntchito popanga biodiesel, ketones, acids ndi mankhwala ena.
2. Heptanaldehyde nthawi zambiri amagwiritsidwa ntchito popanga zonunkhira, ma resin, mapulasitiki, ndi zina zotero.
3. Heptanaldehyde ingagwiritsidwenso ntchito ngati reagent ya mankhwala ndipo ingagwiritsidwe ntchito mu organic synthesis, surfactant ndi zina.
Njira:
Pali njira ziwiri zazikulu zopangira heptanaldehyde:
1. Heptane oxidation: Heptanaldehyde ikhoza kukonzedwa ndi oxidation reaction pakati pa heptane ndi mpweya pa kutentha kwakukulu.
2. Etherification ya vinyl mowa: Heptanal imathanso kupezedwa ndi etherification ya 1,6-hexadiene ndi mowa wa vinyl.
Zambiri Zachitetezo:
1. Heptanaldehyde imakhala ndi fungo lopweteka ndipo imakhala ndi mphamvu yowononga maso ndi kupuma, choncho iyenera kusungidwa kutali ndi maso, pakamwa ndi mphuno.
2. Heptanaldehyde imakwiyitsa khungu, choncho iyenera kutsukidwa ndi madzi mwamsanga mutangokhudzana.
3. Mpweya wa Heptanaldehyde ukhoza kuyambitsa mutu, chizungulire ndi zizindikiro zina zosasangalatsa, ndipo ziyenera kugwiritsidwa ntchito pamalo abwino kwambiri.
4. Heptanaldehyde ndi madzi oyaka, choncho pewani kukhudzana ndi moto wotseguka komanso kutentha kwambiri.
