Trifluoroacetylacetone (TFAA), oo leh qaacidada kiimikaad ee C5H5F3O2, waa xarun isku dhafan oo ka hela codsiyo badan oo dhinacyo kala duwan ah.Waa dareere deggan, oo aan midab lahayn oo leh ur ur daran iyo barta karkarinta hoose. Mid ka mid ah isticmaalka aasaasiga ah ee trifluoroacetylacetone waa wakiilka chelating ee isku-duwidda kimistariga.Waxay leedahay xidhiidh sare oo loogu talagalay ions birta waxayna samayn kartaa dhismo deggan oo leh noocyo kala duwan oo biraha kala-guurka ah.Dhismayaashan birta ah waxaa loo isticmaalaa habab kala duwan oo kicin ah, sida oksaydheynta, hydrogenation-ka, iyo falcelinta samaynta curaarta CC.Dhismayaasha Trifluoroacetylacetone sidoo kale waxaa loo isticmaali karaa sidii dareemayaasha ion birta iyo horudhacyada filimada khafiifka ah ee oksaydhka.Qaab dhismeedka β-diketone wuxuu u oggolaanayaa sameynta noocyo badan oo kala duwan, taasoo ka dhigaysa mid qiimo leh isku-darka dawooyinka iyo kiimikooyinka kale ee wanaagsan.Waxay la kulmi kartaa falcelino kala duwan, oo ay ku jiraan uumiga, falcelinta aldol, iyo beddelka nucleophilic, si ay u soo saaraan xeryahooda kala duwan oo leh sifooyinka la rabo.In goobta sayniska qalabka, trifluoroacetylacetone waxaa loo isticmaali karaa horudhac u ah dhigista filimada khafiifka ah ee oksaydhka birta.Marka la isku daro TFAA iyo cusbada birta ee kaydinta uumiga kiimikada (CVD) ama habka kaydinta lakabka atomiga (ALD), filimada khafiifka ah ee oksaydhyada birta ah sida titanium dioxide ama tin oxide ayaa la samayn karaa.Filimyadani waxay ka helaan codsiyada qalabka semiconductor, unugyada qorraxda, dahaarka lidka-ka-hortagga, iyo dareemayaasha gaaska.Codsiga kale ee muhiimka ah ee trifluoroacetylacetone waa isticmaalka falanqaynta biraha iyo dhismayaasha birta.Waxaa loo shaqeeyaa sidii wakiilka kakan ee farsamooyinka diyaarinta muunada sida soo saarista dareeraha- dareeraha ah iyo ka-saarista wejiga adag.Trifluoroacetylacetone waxay samaysaa dhismayaal xasiloon oo leh ion bir ah, taas oo fududaynaysa kala saaridooda iyo ogaanshaha shaybaarada deegaanka, bayoolojiga, iyo shaybaadhka. Intaa waxa dheer, trifluoroacetylacetone waxaa loo isticmaalaa dardar-geliyaha vulcanization ee soo saarista alaabada caagga ah.Waxay u shaqeysaa sidii co-xawaare leh baaruud ee geeddi-socodka vulcanization, kor u qaadista isku-xidhka u dhexeeya silsiladaha polymer iyo hagaajinta sifooyinka jireed ee alaabta caagga ah, sida barti, adkeysiga, iyo caabbinta kulaylka iyo kiimikooyinka. ka kooban codsiyo ku saabsan kimisteriga isku-duwidda, isku-dhafka organic, sayniska agabka, kimistariga falanqaynta, iyo warshadaha caagga ah.Sifooyinkeeda khiyaamada, falcelinta, iyo awooda samaynta dhismooyin bir ah oo deggan ayaa ka dhigaya qalab qiimo leh oo ku jira hababka sayniska iyo warshadaha ee kala duwan, oo gacan ka geysanaya horumarinta dhinacyo badan.
