Iimveliso

I-Trifluoroacetylacetone (TFAA), kunye nefomyula yekhemikhali C5H5F3O2, yikhompawundi eguquguqukayo efumana izicelo ezininzi kwiinkalo ezahlukeneyo.Ilulwelo oluzinzileyo, olungenambala olunevumba elibi kunye neqondo eliphantsi lokubila.Enye yezinto eziphambili ze-trifluoroacetylacetone njenge-agent ye-chelating kwi-chemistry yokulungelelanisa.Inobudlelwane obuphezulu bee-ion zetsimbi kwaye inokwenza ii-complexes ezizinzile kunye noluhlu olubanzi lweetsimbi zenguqu.Ezi zixhobo zetsimbi zisetyenziswa kwiinkqubo ezahlukeneyo ze-catalytic, ezifana ne-oxidation, i-hydrogenation, kunye ne-CC bond formation reactions.I-Trifluoroacetylacetone complexes nayo ingaqeshwa njengeenzwa ze-ion zetsimbi kwaye njengezandulela ze-metal oxide films thin films synthesis.I-Trifluoroacetylacetone iphinda isetyenziswe njengebhloko yokwakha kwi-organic synthesis.Ubume bayo be-β-diketone buvumela ukuqulunqwa kwezinto ezininzi eziphuma kuyo, okwenza ukuba kube luncedo ekuhlanganiseni amayeza kunye nezinye iikhemikhali ezintle.Iyakwazi ukusabela ngeendlela ezahlukeneyo, kubandakanywa ukuxutywa, ukuphendulwa kwe-aldol, kunye nokutshintshwa kwe-nucleophilic, ukuvelisa uluhlu lweekhompawundi ezineempawu ezifunwayo.Kwintsimi yezinto zesayensi, i-trifluoroacetylacetone ingasetyenziswa njenge-precursor yokubekwa kwe-metal oxide films ezincinci.Ngokudibanisa i-TFAA kunye neetyuwa zetsimbi kwi-chemical vapor deposition (CVD) okanye inkqubo ye-atomic layer deposition (ALD), iifilimu ezincinci zee-oxide zetsimbi ezifana ne-titanium dioxide okanye i-tin oxide inokwakheka.Ezi filimu zifumana izicelo kwizixhobo ze-semiconductor, iiseli zelanga, i-anti-reflective coatings, kunye ne-gas sensors.Esinye isicelo esibalulekileyo se-trifluoroacetylacetone kukusetyenziswa kwayo ekuhlalutyweni kwesinyithi kunye nezixhobo zetsimbi.Iqeshwe njenge-agent eyinkimbinkimbi kwiindlela zokulungiselela isampuli ezifana nokutsalwa kolwelo kunye nesigaba esiqinileyo se-microextraction.I-Trifluoroacetylacetone yenza ii-complexes ezizinzile kunye ne-ion zetsimbi, ziququzelela ukuhlukana kwazo kunye nokufumanisa kwi-esingqongileyo, i-biological, kunye neesampuli ze-forensic.Ukongezelela, i-trifluoroacetylacetone isetyenziswe njenge-accelerator ye-vulcanization ekwenzeni iimveliso zerabha.Isebenza njenge-co-accelerator kunye nesulfure kwinkqubo ye-vulcanization, ukukhuthaza ukudibanisa phakathi kwamaketanga e-polymer kunye nokuphucula iimpawu ezibonakalayo zezixhobo zerabha, ezifana ne-elasticity, ukuqina, kunye nokuchasana nokushisa kunye neekhemikhali.Ngokufutshane, i-trifluoroacetylacetone yinto eninzi ihlanganiswe kunye nokusetyenziswa kwikhemistri yokulungelelanisa, i-organic synthesis, isayensi yezixhobo, ikhemistri yohlalutyo, kunye neshishini lerabha.Iipropathi zayo ze-chelating, i-reactivity, kunye nokukwazi ukwenza ii-metal complexes ezizinzileyo ziyenza ibe sisixhobo esixabisekileyo kwiinkqubo ezahlukeneyo zenzululwazi kunye nezoshishino, igalelo kwinkqubela phambili kwiinkalo ezininzi.
