Mawu Oyamba

2,3-hexanedione (yomwe imadziwikanso kuti pentanedione-2,3) ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2,3-hexanedione:

 

Ubwino:

- Maonekedwe: 2,3-hexanedione ndi kristalo wopanda mtundu wolimba.

- Kusungunuka: Imasungunuka pang'ono m'madzi ndipo imatha kusungunuka mu zosungunulira monga ma alcohols, ethers ndi ma hydrocarbon.

- Polarity: Ndi gulu la polar lomwe limatha kupanga ma hydrogen bond.

 

Gwiritsani ntchito:

- Ntchito zamafakitale: 2,3-hexanedione ingagwiritsidwe ntchito ngati zosungunulira, chothandizira ndi mankhwala apakatikati.

- Kaphatikizidwe ka Chemical: Nthawi zambiri amagwiritsidwa ntchito ngati chinthu chofunikira pakuphatikizika kwachilengedwe ndipo amatha kugwiritsidwa ntchito popanga ma ketoni, ma acid, ndi zinthu zina.

 

Njira:

- Njira ya okosijeni: 2,3-hexanedione ikhoza kukonzedwa ndi makutidwe ndi okosijeni a n-octanol. Oxidizing agents monga oxygen carbonate ndi acid hydrogen peroxide nthawi zambiri amagwiritsidwa ntchito pochita.

- Njira zina zopangira: 2,3-hexanedione, monga oxidene kapena oxanal, imathanso kukonzedwa ndi njira zina zophatikizira.

 

Zambiri Zachitetezo:

- 2,3-Hexanedione imakwiyitsa maso ndi khungu ndipo iyenera kupewedwa mwachindunji.

- Valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi malaya a labu mukamagwiritsa ntchito 2,3-hexanedione.

- Chisamaliro chiyenera kutengedwa kuti mupewe kukhudzana ndi okosijeni posunga ndikugwira 2,3-hexanedione kuteteza moto kapena kuphulika.

- Kutaya zinyalala: Taya zinyalala 2,3-hexanedione mosamala malinga ndi malamulo amderalo kuteteza chilengedwe.
