Intshayelelo
I-2 (1H) -Pyridinone,3-bromo-5-(trifluoromethyl)-(2(1H) -Pyridinone,3-bromo-5-(trifluoromethyl)-) i-organic compound. Inayo i-molecular formula ye-C6H3BrF3NO kunye ne-molecular weight of 218.99g / mol. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko:
Indalo:
-Ukubonakala: 2 (1H) -Pyridinone, 3-bromo-5- (trifluoromethyl) -iqinile, ngokuqhelekileyo imhlophe ukuya kwiikristale eziphuzi.
-Indawo yokunyibilika: Indawo yayo yokunyibilika yi-90-93°C.
-I-Solubility: I-2 (1H) -i-Pyridinone, i-3-bromo-5- (i-trifluoromethyl) -ine-solubility ethile kwii-solvents eziqhelekileyo ze-organic, ezifana ne-ethanol, i-ether kunye ne-chloroform.
Sebenzisa:
-Uphando lwamachiza: 2 (1H) -Pyridinone, 3-bromo-5- (trifluoromethyl) -inokusetyenziswa njenge-reagent okanye ephakathi kwi-organic synthesis. Ihlala isetyenziselwa ukwenza i-skeleton yeemolekyuli ze-organic eziyinkimbinkimbi kwi-metal-catalyzed reactions.
-Uphuhliso lweziyobisi: Ngenxa yesakhiwo esikhethekileyo kunye neekhemikhali, inokudlala indima ebalulekileyo ekuphuhlisweni kweziyobisi, ezifana ne-anti-cancer agents, i-antiviral agents, njl.
Indlela yokulungiselela:
I-2 (1H) -i-Pyridinone, i-3-bromo-5- (i-trifluoromethyl) -inokwenziwa ngeendlela ezahlukeneyo, oku kulandelayo yenye yeendlela eziqhelekileyo zokudibanisa:
I-2-hydroxyl pyridine iphendulwa kunye ne-magnesium bromide ukuvelisa i-2-hydroxyl -3-bromopyridine. I-3-bromopyridine iphinda iphendule nge-fluoromethyllithium ukunika i-2 (1H) -Pyridinone, i-3-bromo-5- (trifluoromethyl) -. I-synthesis ngokubanzi iqhutyelwa kwi-solvent ye-organic, njenge-dimethyl sulfoxide, kunye namaqondo obushushu aphantsi.
Ulwazi ngoKhuseleko: Ukhuseleko lwe
- 2 (1H) -Pyridinone,3-bromo-5-(trifluoromethyl)-ayikavavanywanga ngokucacileyo, ngoko kufuneka kuthathelwe ingqalelo xa uphathwa kwaye ugcina. Abasebenzisi bayacetyiswa ukuba banxibe izixhobo ezifanelekileyo zokuzikhusela, ezinjengeeglavu zelebhu kunye nokhuseleko lwamehlo. Kuphephe ukuphefumla uthuli lwayo okanye ukudibana nolusu.
-Ngenxa yeempawu zayo zeekhemikhali, inokuba yityhefu kwindawo yamanzi. Nceda uthobele iinkqubo ezifanelekileyo zokhuseleko xa usebenzisa, ukuphepha ukukhutshwa kwayo kumzimba wamanzi.
-Xa usebenzisa le ngqungquthela, kucetyiswa ukuba usebenze phantsi kweemeko zebhubhoratri ezinomoya opholileyo ukuze ugweme ukuphefumla ukuguquka kwayo. Kwimeko yokuchitheka ngempazamo okanye ukuphefumla, funa unyango ngokukhawuleza.
