Mawu Oyamba
Acetaldehyde, yomwe imadziwikanso kuti acetaldehyde kapena ethylaldehyde, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha acetaldehyde:
Ubwino:
1. Ndi madzi opanda mtundu okhala ndi zokometsera komanso fungo lamphamvu.
2. Zimasungunuka m'madzi, mowa ndi zosungunulira za ether, ndipo zimatha kusungunuka.
3. Ili ndi polarity yapakatikati ndipo imatha kugwiritsidwa ntchito ngati chosungunulira chabwino.
Gwiritsani ntchito:
1. Amagwiritsidwa ntchito kwambiri popanga mafakitale.
2. Ndi zofunika zopangira kwa synthesis ena mankhwala.
3. Ikhoza kugwiritsidwa ntchito kupanga mankhwala monga vinyl acetate ndi butyl acetate.
Njira:
Pali njira zingapo zopangira acetaldehyde, yomwe nthawi zambiri imapangidwa ndi catalytic oxidation ya ethylene. Njirayi ikuchitika pogwiritsa ntchito okosijeni ndi zitsulo zothandizira (mwachitsanzo, cobalt, iridium).
Zambiri Zachitetezo:
1. Ndi chinthu chapoizoni, chomwe chimakwiyitsa khungu, maso, kupuma ndi dongosolo la m'mimba.
2. Ndi madzi oyaka, omwe angayambitse moto pamene akuwonekera pamoto wotseguka kapena kutentha kwakukulu.
3. Njira zoyenera zotetezera ziyenera kuchitidwa pogwiritsa ntchito acetaldehyde, monga kuvala magolovesi otetezera, magalasi ndi zopumira, ndikuwonetsetsa kuti zimagwira ntchito pamalo abwino.
