ACETYL ACETONE (2,4 PENTANEDIONE)

Acetylacetone, izwi kandi nka 2, 4-pentadione, ni ifumbire mvaruganda, imiti ya C5H8O2, ibara ritagira ibara ryumuhondo rikeya ryoroshye, rishonga gato mumazi, hamwe na Ethanol, ether, chloroform, acetone, acide acetike hamwe nandi mashanyarazi akoreshwa nabi, cyane cyane ikoreshwa nka solvent, agent ikuramo, irashobora kandi gukoreshwa mugutegura inyongeramusaruro ya lisansi, amavuta, udukoko twica udukoko, imiti yica udukoko, amarangi, nibindi.

Ibyiza:Acetone idafite ibara cyangwa ibara ry'umuhondo ryaka umuriro.Ahantu ho gutekera ni 135-137 ° C, flash flash ni 34 ° C, naho gushonga ni -23 ° C. Ubucucike bugereranije ni 0,976, igiciro cyo kugabanywa ni N20d1.4512.Acetone irashobora gushonga muri 8g y'amazi, kandi ikavangwa na Ethanol, benzene, chloroform, ether, acetone, na acide methampitike, ikabora acetone na acide acetike mumuti wa alkali.Iyo bigeze ku muriro mwinshi, umuriro woroheje na okiside ikomeye, biroroshye gutera umuriro.Kudahungabana mumazi, byoroshye hydrolyzed muri acide acetike na acetone.

Hagati ya synthesis organique:

Acetylacetone ni intera ikomeye hagati ya synthesis organique, ikoreshwa cyane muri farumasi, impumuro nziza, imiti yica udukoko nizindi nganda.

Acetone ni ibikoresho byingenzi mu nganda zimiti, nka synthesis ya 4,6 - dimethylpyrimidine.Irakoreshwa kandi nk'umuti wa acetate ya selile, desiccant yo gusiga amarangi na langi, hamwe na reagent ikomeye yo gusesengura.

Bitewe no kubaho kwa enol, acetylacetone irashobora gukora chelates hamwe na cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminium, chromium, fer (Ⅱ), umuringa, nikel, palladium, zinc, indium, amabati, zirconium, magnesium, manganese, scandium na thorium hamwe nizindi ion zicyuma, zishobora gukoreshwa nkinyongera mumavuta ya lisansi namavuta yo gusiga.

Igitabo cya Chemical kirashobora gukoreshwa nkibikoresho byoza ibyuma muri micropores hamwe na chelation hamwe nibyuma.Ikoreshwa nka catalizator, resin ihuza imiyoboro, resin ikiza yihuta;Ibisigarira, inyongeramusaruro;Ikoreshwa kuri hydroxylation reaction, reaction ya hydrogenation, reaction ya isomerisation, synthesis ya ketone nkeya ituzuye hamwe na carbone olefin polymerisation na copolymerisation;Ikoreshwa nka organic solvent, ikoreshwa muri selile acetate, wino, pigment;Ibikoresho byo kumisha irangi;Ibikoresho bibisi byo gutegura udukoko twica udukoko na fungiside, imiti igabanya ubukana bwinyamaswa ninyongeramusaruro;Ikirahure cyerekana imirasire, firime ikora neza (umunyu wa indium), firime ikora cyane (umunyu wa indium);Icyuma cya Acetylacetone gifite ibara ryihariye (umunyu wumuringa icyatsi, umunyu wicyuma gitukura, umunyu wa chromium wijimye) kandi udashonga mumazi;Ikoreshwa nkibikoresho fatizo byubuvuzi;Ibikoresho ngengabihe.

Porogaramu ya ACETYL ACETONE：

1. Pentanedione, izwi kandi nka acetylacetone, ni intera hagati ya fungicide pyraclostrobin, azoxystrobin na herbicide rimsulfuron.

2. Irashobora gukoreshwa nkibikoresho fatizo n’umuhuza w’ibikoresho bya farumasi, kandi birashobora no gukoreshwa nkumuti.

3. Ikoreshwa nka analytique reagent nogukuramo aluminium muri tungsten na molybdenum.

4. Acetylacetone ni intera hagati ya synthesis organique, kandi ikora amino-4,6-dimethylpyrimidine hamwe na guanidine, nikintu cyingenzi cya farumasi.Irashobora gukoreshwa nk'umuti wa acetate ya selile, inyongeramusaruro ya lisansi n'amavuta, desiccant yo gusiga irangi na langi, fungiside, hamwe nudukoko twica udukoko.Acetylacetone irashobora kandi gukoreshwa nkumusemburo wa peteroli, hydrogène na carbonylation, hamwe na okiside yihuta ya ogisijeni.Irashobora gukoreshwa mugukuraho okiside yicyuma mumyanda ikomeye no kuvura catalizike ya polypropilene.Mu bihugu by’Uburayi n’Amerika, abarenga 50% bakoreshwa mu bworozi bw’amatungo antidiarrheal n’inyongeramusaruro.

5. Usibye imiterere isanzwe ya alcool na ketone, irerekana kandi ibara ry'umutuku wijimye hamwe na chloride ferricike kandi ikora chelates hamwe numunyu mwinshi wibyuma.Hamwe na anhydride ya acetike cyangwa acetyl chloride hamwe na acetone ya acetone, cyangwa nukuntu reaction ya acetone na ketene yabonetse.Igitabo cya chimique gikoreshwa nkibikurura ibyuma kugirango bitandukane ion zingana na tetravalent, ibyuma byangiza amarangi na wino, imiti yica udukoko, imiti yica udukoko, fungiside, imiti ya polymers ndende, reagent kugirango hamenyekane abahuza thallium, fer, fluor, na synthesis organique.

6. Inzibacyuho yicyuma.Kugena amabara ya fer na fluor, no kugena thallium imbere ya karubone disulfide.

7. Fe (III) icyerekezo cyerekana titre;ikoreshwa muguhindura amatsinda ya guanidine (nka Arg) hamwe nitsinda rya amino muri proteyine.

8. Ikoreshwa nkibikoresho byinzibacyuho;ikoreshwa muguhitamo amabara ya fer na fluor, no kugena thallium imbere ya karubone disulfide.

9. Ikimenyetso cyicyuma (III) cyitiriwe titre.Byakoreshejwe muguhindura amatsinda ya guanidine muri poroteyine hamwe nitsinda rya amino muri proteyine.

Imiterere yo kubika:

1. Irinde Minghuo na okiside ikomeye, kashe kandi ubike.

2. Wizingire mu gikapu cya pulasitike cyangwa muri plastiki ya pulasitike mu cyuma cy'icyuma; Ubusanzwe gupakira ibicuruzwa: 200kg / ingoma. Ikirinda umuriro, kirinda umuriro, kitagira amazi, kibitswe mu bubiko buteye akaga.Kubika no gutwara ukurikije amabwiriza yimiti yangiza.
