Acetyl acetone (2,4 pentanese)

Acetylacetone,also known as 2, 4-pentadione, is an organic compound, chemical formula C5H8O2, colorless to slightly yellow transparent liquid, slightly soluble in water, and ethanol, ether, chloroform, acetone, ice acetic acid and other organic solvents miscible, mainly ikoreshwa nkibintu, umukozi wo gukuramo, birashobora kandi gukoreshwa mugutegura abongesheje lisansi, lubriricants, kubumba Udukoko, imiti yica udukoko, dyes, nibindi.

Umutungo:Acetone ni ibara ritagira ibara cyangwa ryumuhondo gato. Ingingo yo guteka ni 135-137 ° C, Flash Point ni 34 ° C, hamwe ningingo yo gushonga ni -23 ° C. Ubucucike bwa C. Acetone irashonje muri 8G yamazi, kandi ivanze na Ethanol, Bengene, Chloroform, Ether, acide, na acide ya acetone na acetitike mubikorwa bya alkali. Ku bijyanye n'umuriro mwinshi, umuriro woroheje n'inzira zikomeye, biroroshye gutera umuriro. Idahungabana mumazi, byoroshye hydrolyzed muri acide ya acetic na acetone.

Hagati ya synthesis kama:

Acetylacetone ningirakamaro muri synthesis kama, ikoreshwa cyane muri farumasi, impumuro nziza, yica udukoko nizindi nganda.

Acetone ni ibikoresho byingenzi byingenzi mubikorwa bya farumasi, nka synthesis ya 4,6 - Dimethylnidididine. Irakoreshwa kandi nka reserture ya selile, desicant yo gushushanya na tapi, hamwe na reagent yimiserani.

Bitewe no kubaho kwa enol, acetylacetone irashobora gukora chelate hamwe na coabant (ⅱ), cosryllium, ibyuma, Ickel, Ickel, Icyuma, Ibnetium, Magnesium, Manganese, Scandium na Thorium hamwe nizindi cyuma, zishobora gukoreshwa nkinyongera muri Amavuta ya lisansi n'amavuta yo gusiga.

Igitabo cyigitabo kirashobora gukoreshwa nkumukozi usukura ibyuma muri micropores na chelation yayo hamwe nibuka. Ikoreshwa nka catalyst, resin agent agent, resin akiza yihuta; Resin, ibiyobyabwenge bya reberi; Ikoreshwa kuri hydroxy, reaction ya hydrogenation, intungane ya somemenation, molebulari nkeya ya ketone idakuze hamwe na karubone ntoya ya karubone hamwe na copofin; Ikoreshwa nka socit organic, ikoreshwa kuri acetate ya selile, wino, pigment; Amarangi yumisha; Ibikoresho fatizo byo gutegura udukoko hamwe na fungicide, ibiyobyabwenge bya antidiarrtheal no kugaburira inyongeramusaruro; Inzitizi zigaragaza ikirahure, film itwara imbonerahamwe (umunyu w indium), firime ya superconducting (umunyu w indium) gushiraho umukozi; Acetylacetone Icyuma gifite ibara ryihariye (umunyu wumuringa wicyatsi, icyuma gitukura, chromium umutuku) kandi bidahunze mumazi; Ikoreshwa nkibikoresho fatizo byubuvuzi; Ibikoresho bya kama.

Gusaba Acetyl Acetone:

1. Pentanedione, uzwi kandi nka acetylacetotone, ni hagati ya fungicide pyraclostrobin, Azoxystrobin, Azoxystrobin na Rimsulide Rimulfuron.

2. Irashobora gukoreshwa nkibikoresho fatizo hamwe na kama hagati ya faruotique, kandi irashobora kandi gukoreshwa nkibintu.

3. Ikoreshwa nk'isesengura ryisesengura no gukuramo aluminiyumu muri Tungsten na Molybdenum.

4.. Irashobora gukoreshwa nkigisubizo cya selile, akongeraho lisansi hamwe na libine na lubricants, ashishikajwe no gusiga irangi nigicapo, igihuru, nurupfu. Acetylacetone irashobora kandi gukoreshwa nkumusemburo kuri peteroli ya peteroli, hydrorognation hamwe nibitekerezo bya kamera, hamwe na okiside ya ogisijeni. Irashobora gukoreshwa kugirango ukureho inzitizi yicyuma muburyo bwiza no kuvura polypropylene catalilests. Mu bihugu by'Uburayi n'Abanyamerika, birenga 50% bikoreshwa mu matungo antintirher ibiyobyabwenge no kugaburira inyongeramusaruro.

5. Usibye imitungo isanzwe ya alcool na ketones, nayo igaragaza ibara ryijimye ritukura hamwe na chloride hamwe na chloride hamwe na chlorite hamwe nimpyi nyinshi. Nukuguru ka Acetic Anthyride cyangwa acetyl chloride na acetone contensation, cyangwa kubisubizo bya acetone na keene babonye. Igitabo cya chimical gikoreshwa nkicyuma kigera kuri kion yo mukikoriko na tetravanyont, irangi na wino, imiti yica udukoko.

6. Inzozi Zinzitizi. Ibara ryamabara kugena icyuma na fluorine, no kugena thallium imbere ya karubone idasuzuguritse.

7. FE (iii) icyerekezo cy'igihanganonger; ikoreshwa muguhindura amatsinda ya Guanine (nka ARG) hamwe nitsinda rya amino muri poroteyine.

8. Ikoreshwa nkinzibacyuho yinzibacyuho; ikoreshwa mu kugena imiterere y'icyuma na fluorine, no kugena thallium imbere ya karubone idasuzuguritse.

9. Ikimenyetso cyicyuma (III) imigambi igoye. Ikoreshwa mu guhindura amatsinda ya Guanine muri poroteyine na amino amatsinda muri poroteyine.

Imiterere yo kubika:

1. Guma kure ya Minghuo na Okiside ikomeye, kashe hanyuma uzigame.

2. Kuzinga mu gikapu cya plastiki cyangwa ingurube ya plastike mucyuma; Igipfukisho gisanzwe: 200kg / ingoma, ibihamya, ibihamya, bibitswe mu bubiko bute. Ububiko no gutwara abantu ukurikije amabwiriza yimiti mibi.
