koma-3-yn-2-one (CAS # 1423-60-5) chiyambi
3-butyne-2-imodzi. Zotsatirazi ndizofotokozera za chikhalidwe chake, cholinga chake, njira yopangira, ndi chidziwitso cha chitetezo:
chilengedwe:
-Maonekedwe: 3-Butyn-2-imodzi ndi madzi achikasu opepuka opanda mtundu.
-Kununkhira: Kumakhala ndi fungo lofanana ndi mowa ndi zipatso.
-Kusungunuka: kusungunuka mu zosungunulira zambiri monga ma alcohols ndi ethers.
Cholinga:
-3-butyne-2-one imagwiritsidwa ntchito kwambiri popanga organic synthesis. Itha kugwiritsidwa ntchito ngati zopangira, chothandizira, ndi zosungunulira pamachitidwe amankhwala, ndipo imatha kutenga nawo gawo pazosintha zosiyanasiyana zama organic synthesis, monga ma nucleophilic substitution reaction and coupling reaction.
Njira yopanga:
- Njira imodzi yokonzekera 3-butyne-2-one ndi momwe acetone amachitira ndi mowa wa propargyl. Choyamba, acetone imayendetsedwa ndi sodium hydroxide yochulukirapo kuti ipeze sodium acetate, yomwe imachitidwa ndi mowa wa propargyl mu chotengera mpweya kuti apange 3-butyne-2-one.
-Pali njira zina zosiyanasiyana zopangira 3-butyne-2-one, monga kulekanitsa ndi kuyeretsa zinthu zachilengedwe zokhudzana ndi chilengedwe, pogwiritsa ntchito njira zopangira mankhwala, ndi zina zotero.
Zambiri zachitetezo:
-3-Butyn-2-one imakwiyitsa maso, khungu, ndi kupuma, ndipo iyenera kutsukidwa ndi madzi ikakhudza.
- Pewani kukhudzana ndi ma oxidants amphamvu, ma acid amphamvu, ndi maziko amphamvu kuti mupewe zoopsa.
-Pogwiritsa ntchito 3-butyne-2-one, magolovesi oteteza mankhwala, magalasi, ndi chigoba choteteza ziyenera kuvala kuti zitsimikizire kuti mpweya wabwino umakhala wabwino.
Awa ndi mawu oyamba okhudza katundu, ntchito, njira zokonzekera, ndi chidziwitso cha chitetezo cha 3-butyne-2-one. Mukamagwiritsa ntchito ndikugwiritsa ntchito pagululi, chonde onetsetsani kuti mwatsata njira zoyendetsera chitetezo ndikuwunikira zambiri zokhudzana ndi chitetezo ndi Blue Book of Chemical Substances.
