Codsiyada acetyl acetone:
1. Pentanadedione, oo sidoo kale loo yaqaan Acetynylacetone, waa dhexdhexaadiyaha fangaska fangaska Pyriclostrodrodrod, azoxystrobin iyo dhirta subka subka ah.
2. Waxaa loo istcimaali karaa sida qalabka ceyriinka iyo dhex-dhexaadka dabiiciga ah ee dawooyinka, waxaana sidoo kale loo isticmaali karaa solvents.
3. Waxaa loo adeegsaday sidii dib-u-habeyn falanqayn iyo wakiilka soo saarista aluminium ee ku tungsten iyo molybdenum.
4. Acethuyctonetone waa mid dhexe oo isku-dhafan isku-darka dabiiciga ah, oo waxay ku foororsataa amino-4,6-gamethylpyrimine oo leh Guandine, oo ah qalab cayriin ah oo muhiim ah. Waxaa loo isticmaali karaa sidii solvent loogu tala galay unugyada cellulose acetate, oo wax lagu daro shidaal iyo saliid darooga ah, oo loo baahan yahay rinji iyo varnish, sunta sunta, iyo cayayaanka. Acetylacetone waxaa sidoo kale loo isticmaali karaa inay u dhintaan sidii wax u dhimaya dilitaanka batroolka, hydrogenition iyo falcelinta carbobiska, iyo dardar-darrooyinka oksijiinta ee oksijiinta. Waxaa loo isticmaali karaa in laga saaro oxides bir ah oo ku dhaca adkaynta adag oo lagu daaweeyo wax lagu isticmaalo polypropyleners. Wadamada Yurub iyo Mareykanka, in kabadan 50% waxaa loo isticmaalaa in dawooyinka lidka ku ah xoolaha iyo quudinta waxyaabaha lagu daro.
5. Marka lagu daro astaamaha caadiga ah ee aalkolada iyo ketones, waxay sidoo kale soo bandhigtaa midab guduudan oo madow oo leh chloride-ka mugdiga ah waxayna sameeyaan cliletes bir badan oo bir ah. By acetic andydride ama acetyl chloride iyo cufnaanta acetone, ama falcelinta acetone iyo kenet la helay. Xannibaarka kiimikada waxaa loo isticmaalaa sidii bir-qabad oo bir ah oo laga soo saaro ionsigent and tempanites-ka, darida cayayaanka, sunta cayayaanka, cayayaanka, folorine-ka, fluorindine, iyo isku-darka isku-dhafka ah.
6. Cirbado bir ah oo kala-guurka ah. Go'aaminta midabka midabka midabka birta iyo foloriinka, iyo go'aaminta tuugaynta tuurista kaarboon-baxa.
7. Fe (III) Tilmaanta cinwaanada ee isku-dhafka ah; Waxaa loo isticmaalaa in wax laga beddelo kooxaha Gunidine (sida Arg) iyo kooxaha AMINno ee borotiinnada.
8. Waxaa loo adeegsaday sidii wakiilka birta ee ka-gudbinta; Waxaa loo adeegsaday go'aaminta midabka midabka bir iyo foloriine, iyo go'aaminta tuugaynta tuugada kaarboonka wasakhoodu.
9. Tilmaanta macdanta birta (iii) qanjirka adag. Waxaa loo adeegsaday in wax laga beddelo kooxaha Gunidine ee borotiinnada iyo kooxaha Amino ee borotiinnada.
Xaaladaha Kaydinta:
1. Ka fogow Minghuo iyo osbitaalka adag, shaabad oo badbaadi.
2. Ku duub bac balaastig ah ama foosto caag ah oo ku yaal baakadaha birta; Kaydinta iyo gaadiidka iyadoo loo eegayo qawaaniinta kiimikooyinka halista ah.
