Intshayelelo
I-2,3-hexanedione (eyaziwa nangokuthi i-pentanedione-2,3) i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2,3-hexanedione:
Umgangatho:
- Imbonakalo: I-2,3-hexanedione yinto eqinileyo yekristale engenambala.
- Ukunyibilika: Inyibilika ngokuyinxenye emanzini kwaye inyibilika ngakumbi kwizinyibilikisi zendalo ezifana neealkoholi, ii-ethers kunye neehydrocarbons.
- I-Polarity: Yikhompawundi ye-polar enokwenza iibhondi ze-hydrogen.
Sebenzisa:
- Izicelo zoshishino: I-2,3-hexanedione ingasetyenziselwa njenge-solvent, i-catalyst kunye ne-chemical intermediate.
- I-Chemical synthesis: Ihlala isetyenziswa njengento ebalulekileyo ekrwada kwi-organic synthesis kwaye ingasetyenziselwa ukudibanisa i-ketones, i-acids, kunye nezinye iikhompawundi.
Indlela:
- Indlela ye-Oxidation: I-2,3-hexanedione inokulungiswa ngokuphendula kwe-oxidation ye-n-octanol. Ii-oxidizing agents ezifana ne-oxygen carbonate kunye ne-asidi ye-hydrogen peroxide zihlala zisetyenziswa ekuphenduleni.
- Ezinye iindlela zokwenziwa: i-2,3-hexanedione, njenge-oxidene okanye i-oxanal, ingalungiswa ngezinye iindlela zokudibanisa.
Ulwazi ngoKhuseleko:
- I-2,3-Hexanedione iyacaphukisa amehlo kunye nesikhumba kwaye kufuneka igwenywe ngokuqhagamshelana ngqo.
- Nxiba izixhobo ezifanelekileyo zokukhusela ezifana neiglavu, iiglavu, kunye neengubo zelebhu xa usebenzisa okanye uphethe i-2,3-hexanedione.
- Kufuneka kuthathelwe ingqalelo ukuphepha ukudibana nee-oxidants xa ugcina kwaye uphatha i-2,3-hexanedione ukuthintela umlilo okanye ugqabhuko-dubulo.
- Ukulahla inkunkuma: Ukulahla inkunkuma ye-2,3-hexanedione ngokukhuselekileyo ngokuhambelana nemimiselo yendawo ukukhusela indalo.
