Intshayelelo
I-2,4-Dimethyl-5-acetylthiazole i-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwale khompawundi:
Umgangatho:
- Ukubonakala: I-2,4-Dimethyl-5-acetylthiazole i-crystalline engenambala ekhanyayo okanye i-powder eqinile.
- Ukunyibilika: Inyibilika kuninzi lwezinyibilikisi zendalo ezifana ne-ethanol, i-ether kunye ne-acetone, kwaye inyibilika kancinane emanzini.
Sebenzisa:
- Amayeza okubulala izitshabalalisi: 2,4-dimethyl-5-acetylthiazole sisibulali zinambuzane esibanzi esisetyenziselwa ukulawula izitshabalalisi zezityalo ezifana nenundu eliqengqelekayo kunye nekhaphetshu.
Indlela:
- I-2,4-Dimethyl-5-acetylthiazole ngokuqhelekileyo ilungiselelwe ngokuphendula i-2,4-dimethylthiazole kunye ne-acylating agent efana ne-acetyl chloride. Ukusabela kuqhutyelwa kwi-solvent efanelekileyo, ishushu kwaye ishukunyiswe ixesha elithile, kwaye ihlanjululwe nge-crystallization okanye i-filtration.
Ulwazi ngoKhuseleko:
-Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu zelebhu kunye neeglasi zokukhusela ngexesha lomsebenzi woshishino.
• Kulumkele ukudibana nolusu kunye nokuphefumla uthuli, umsi, okanye iigesi ezivela kwikhompawundi.
- Xa ugcina, gcina kwisingxobo esingangeni moya, kude nomlilo kunye nee-oxidants.
- Ngexesha lokusetyenziswa, kuyimfuneko ukulandela imigaqo yokusebenza yokhuseleko olufanelekileyo kwaye uthathe amanyathelo afanelekileyo oncedo lokuqala ngokukhawuleza xa kwenzeka ingozi. Kwimeko yokuphefumla ngempazamo okanye ukungena ngempazamo, funa unyango ngokukhawuleza.
