Mawu Oyamba

2-pentanone, yomwe imadziwikanso kuti pentanone, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2-pentanone:

Ubwino:

- Maonekedwe: 2-pentanone ndi madzi opanda mtundu okhala ndi fungo lapadera.

- Kusungunuka: Itha kusungunuka m'madzi komanso imasakanikirana ndi zosungunulira zambiri.

- Kutentha: 2-pentanone ndi madzi oyaka omwe amatha kuyambitsa moto ngati lawi lotseguka kapena kutentha kwambiri.

Gwiritsani ntchito:

- Kugwiritsa ntchito mafakitale: 2-pentanone imagwiritsidwa ntchito ngati chosungunulira popanga zokutira, inki, zomatira, etc., monga diluent, kuyeretsa wothandizila, ndi reaction wapakatikati.

Njira:

- 2-pentanone nthawi zambiri imakonzedwa ndi oxidizing pentanol. Njira yodziwika bwino ndiyo kuchitapo kanthu ndi pentanol pogwiritsa ntchito okosijeni monga oxygen kapena hydrogen peroxide, ndikufulumizitsa zomwe zimachitika ndi chothandizira monga potaziyamu chromate kapena cerium oxide.

Zambiri Zachitetezo:

- 2-pentaone ndi yoyaka ndipo iyenera kusungidwa kutali ndi moto wotseguka komanso kutentha kwambiri.

- Valani magolovesi odzitchinjiriza, magalasi odzitchinjiriza, ndi chishango choteteza kumaso kuti musakhudze maso, khungu, ndi nthunzi.

- Zinyalala zikuyenera kutayidwa motsatira malamulo ndi malamulo a m'deralo, ndipo zisamatayidwe m'madzi kapena chilengedwe.

- Mukasunga ndikugwiritsa ntchito, chonde tsatirani mosamalitsa njira zoyendetsera chitetezo ndi malangizo kuti muwonetsetse kuti zikugwiritsidwa ntchito moyenera komanso kusungidwa bwino.
