1,1-dibromo-3,3,3-trifluoroacetone wani fili ne na kwayoyin halitta tare da tsarin sinadarai C3Br2F3O. Mai zuwa shine bayanin kaddarorin, amfani, shiri da bayanan aminci na fili:
Hali:
-Bayyana: 1,1-dibromo-3,3,3-trifluoroacetone mara launi ne zuwa ruwan rawaya mai haske ko ƙwaƙƙwaran crystalline.
- Girman: 1.98g/cm³
- Matsakaicin narkewa: 44-45 ℃
-Tafasa: 96-98 ℃
- Solubility: Mai narkewa a cikin ruwa, ethanol da ether.
Amfani:
- 1,1-dibromo-3,3,3-trifluoroacetone an fi amfani dashi azaman reagent na kira na halitta kuma ana iya amfani dashi don shirya wasu mahadi.
- Hakanan za'a iya amfani da fili a matsayin mai kara kuzari, surfactant, da kuma a aikace-aikacen dakin gwaje-gwaje don tantance mita microwave.
Hanyar Shiri:
1,1-dibromo-3,3,3-trifluoroacetone za a iya shirya ta matakai masu zuwa:
1. Na farko, acetone yana amsawa tare da bromine trifluoride don samar da 3,3, 3-trifluoroacetone.
2. Na gaba, a ƙarƙashin yanayi masu dacewa, 3,3,3-trifluoroacetone yana amsawa tare da bromine don samar da 1,1-dibromo-3,3,3-trifluoroacetone.
Bayanin Tsaro:
1,1-dibromo-3,3,3-trifluoroacetone wani nau'in bromine ne na kwayoyin halitta tare da wasu guba da lalata. Kula da abubuwan aminci masu zuwa lokacin amfani:
-A guji tuntuɓar fata da idanu kai tsaye, sanya safar hannu na kariya, tabarau na kariya da abin rufe fuska idan ya cancanta.
-Aiki a cikin iska don guje wa shakar iskar gas ko tururi.
-A guji haɗuwa da oxidants da combustibles yayin ajiya, kuma sanya su a cikin rufaffiyar akwati, nesa da tushen wuta da wuraren zafi mai zafi.
-A guji tartsatsin wuta da lantarki a tsaye yayin amfani da shi don hana wuta ko fashewa.
Lura cewa 1,1-dibromo-3,3,3-trifluoroacetone ƙwararren reagent ne na dakin gwaje-gwaje, wanda ƙwararru kawai za su iya amfani da shi a ƙarƙashin yanayin da ya dace kuma bai kamata a yi amfani da shi ko sarrafa yadda ake so ba.
