Isingeniso

I-2,3-hexanedione (eyaziwa nangokuthi i-pentanedione-2,3) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2,3-hexanedione:

 

Ikhwalithi:

- Ukubukeka: I-2,3-hexanedione iyi-crystalline solid solid.

- Ukunyibilika: Incibilika kancane emanzini futhi incibilika kakhulu kuzincibilikisi zemvelo ezifana notshwala, ama-ether nama-hydrocarbon.

- I-Polarity: Kuyinhlanganisela ye-polar engakha amabhondi e-hydrogen.

 

Sebenzisa:

- Izicelo zezimboni: I-2,3-hexanedione ingasetshenziswa njenge-solvent, i-catalyst kanye namakhemikhali aphakathi.

- Chemical synthesis: Ivamise ukusetshenziswa njengento eluhlaza ebalulekile ekuhlanganiseni kwe-organic futhi ingasetshenziswa ukwenza ama-ketone, ama-asidi, nezinye izinhlanganisela.

 

Indlela:

- Indlela ye-Oxidation: I-2,3-hexanedione ingalungiswa ngokusabela kwe-oxidation ye-n-octanol. Ama-oxidizing agents afana ne-oxygen carbonate ne-acid hydrogen peroxide avame ukusetshenziswa ekuphenduleni.

- Eminye imizila yokwenziwa: i-2,3-hexanedione, njenge-oxidene noma i-oxanal, ingabuye ilungiswe ngezinye izindlela zokuhlanganisa.

 

Ulwazi Lokuphepha:

- I-2,3-Hexanedione iyacasula emehlweni nasesikhumbeni futhi kufanele igwenywe ngokuthintana ngqo.

- Gqoka okokuvikela okufanele njengamagilavu, izibuko, namajazi elebhu lapho usebenzisa noma uphethe i-2,3-hexanedione.

- Kufanele kuqashelwe ukugwema ukuthintana nama-oxidants lapho ugcina futhi uphatha i-2,3-hexanedione ukuvimbela umlilo noma ukuqhuma.

- Ukulahlwa kukadoti: Lahla imfucuza engu-2,3-hexanedione ngokuphepha ngokuhambisana nemithetho yendawo ukuze kuvikelwe imvelo.
