ACETYL ACETONE (2,4 PENTANEDIONE)

Asetilasetoni,izwi kandi nka 2, 4-pentadione, ni imvange y’umwimerere, formula ya shimi C5H8O2, idafite ibara cyangwa umuhondo gato, ishongesha gato mu mazi, kandi ethanol, ether, chloroform, acetone, aside acetic barafu n’ibindi bintu bivangwa n’ibinyabuzima, bikoreshwa cyane nk’ibintu bivangwa n’amazi, bishobora no gukoreshwa mu gutegura inyongeramusaruro za lisansi, amavuta, imiti yica udukoko, imiti yica udukoko, amarangi, n’ibindi.

Imitungo:Asetone ni amazi adafite ibara cyangwa umuhondo utwika gato. Ahantu hashyuha ni 135-137 ° C, aho ishyuha ni 34 ° C, naho aho ishongesha ni -23 ° C. Ubucucike ni 0.976, igipimo cyo kugabanyirizwa ni N20d1.4512. Asetone ishongeshwa muri 8g y'amazi, kandi ivangwa na ethanol, benzene, chloroform, ether, asetone, na aside methampitic, kandi ihinduka asetone na aside asetiki mu gisubizo cya alkali. Iyo bigeze ku muriro mwinshi, umuriro woroheje na okiside ikomeye, biroroshye kuyitwika. Idahinduka mu mazi, yoroshye kuyihindura aside asetiki na asetoni.

Intera yo guhuza organic:

Asetilacetone ni ingenzi mu gukora imisemburo y’ibinyabuzima, ikoreshwa cyane mu nganda zikora imiti, impumuro nziza, imiti yica udukoko n’izindi nganda.

Asetone ni igikoresho cy'ingenzi mu nganda zikora imiti, nko gukora ibikomoka kuri dimethylpyrimidine 4,6. Ikoreshwa kandi nk'umusemburo wa cellulose acetate, desiccant yo gusiga amarangi na varnish, ndetse n'ikintu cy'ingenzi cyo gusesengura.

Bitewe n'uko hariho ubwoko bwa enol, acetylacetone ishobora gukora chelate hamwe na cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminiyumu, chromium, icyuma (Ⅱ), umuringa, nikeli, palladium, zinki, indium, tin, zirconium, manyeziyumu, manganese, scandium na thorium n'izindi iyoni z'icyuma, zishobora gukoreshwa nk'inyongera mu mavuta n'amavuta yo kwisiga.

Igitabo cya Chemicalbook gishobora gukoreshwa nk'umuti wo gusukura ibyuma biri mu mikorobe binyuze mu kuyungurura ibyuma. Gikoreshwa nk'umuti ugabanya ubushyuhe, umuti uhuza resin, umuvuduko wo gukangura resin; Resin, inyongera za rubber; Gikoreshwa mu gukora hydroxylation, hydrogenation reaction, isomerization reaction, low molecular unsaturated ketone synthesis na low carbon olefin polymerization na copolymerization; Gikoreshwa nk'umuti w'umwimerere, gikoreshwa mu gukora cellulose acetate, wino, irangi; Umuti wumisha irangi; Ibikoresho fatizo byo gutegura imiti yica udukoko n'imiti yica udukoko, imiti irwanya impiswi mu matungo n'inyongera ku biryo; Ikirahure cyo kwerekana infrared, filime ibonerana (umunyu wa indium), filime ikora superconducting (umunyu wa indium); Acetylacetone metal complex ifite ibara ryihariye (umunyu w'umuringa icyatsi, umunyu w'icyuma umutuku, umunyu wa chromium) kandi ntishobora gushonga mu mazi; Gikoreshwa nk'ibikoresho fatizo byo kuvura; Ibikoresho by'umwimerere.

Imikoreshereze ya ACETYL ACETONE:

1. Pentanedione, izwi kandi ku izina rya acetylacetone, ni yo ikoreshwa mu gutera imiti yica udukoko nka pyraclostrobin, azoxystrobin na rimsulfuron.

2. Ishobora gukoreshwa nk'ibikoresho fatizo n'ibikomoka ku bimera mu miti, ndetse ishobora no gukoreshwa nk'ibishongesha.

3. Ikoreshwa nk'igikoresho cyo gusesengura no gukurura aluminiyumu muri tungsten na molybdenum.

4. Asetilacetone ni igikoresho cy’ingenzi mu gukora organic synthesis, kandi ikora amino-4,6-dimethylpyrimidine hamwe na guanidine, ikaba ari igikoresho cy’ingenzi mu buvuzi. Ishobora gukoreshwa nk'umusemburo wa cellulose acetate, inyongeramusaruro ya lisansi n'amavuta, desiccant yo gusiga irangi na varnish, fungicide, n'umuti wica udukoko. Asetilacetone ishobora kandi gukoreshwa nk'umusemburo wo gucika kwa peteroli, hydrogenation na carbonylation reactions, ndetse n'umusemburo wo kwihutisha ogisijeni. Ishobora gukoreshwa mu gukuraho ogiside z'icyuma mu bintu bikomeye bifite imyenge no kuvura catalysts za polypropylene. Mu bihugu by'i Burayi na Amerika, ibirenga 50% bikoreshwa mu miti irwanya impiswi n'ibiryo by'amatungo.

5. Uretse imiterere isanzwe ya alkoholi na ketone, inagaragaza ibara ry'umutuku wijimye hamwe na ferric chloride kandi ikora chelate hamwe n'imyunyu myinshi y'icyuma. Binyuze muri acetic anhydride cyangwa acetyl chloride na acetone condensation, cyangwa binyuze mu buryo acetone na ketene byabonetse. Chemicalbook ikoreshwa nk'icyuma gikuramo iyoni mu gutandukanya iyoni za trivalenti na tetravalenti, irangi n'inki byumisha, imiti yica udukoko, imiti yica udukoko, fungicides, solvents kuri polymer nyinshi, reagents zo kumenya thallium, icyuma, fluorine, n'ibintu bihuza organic synthesis.

6. Impinduka mu byuma bipima ubushyuhe. Gupima icyuma na fluorine mu buryo bw'amabara, no kumenya thallium mu gihe hari disulfide ya karuboni.

7. Ikimenyetso cya Fe(III) complexometric titration; gikoreshwa mu guhindura amatsinda ya guanidine (nka Arg) n'amatsinda ya amine muri poroteyine.

8. Ikoreshwa nk'igikoresho cyo guhindura icyuma gipima ubushyuhe; ikoreshwa mu kumenya icyuma na fluorine mu buryo bw'amabara, no kumenya thallium mu gihe hari disulfide ya karuboni.

9. Ikimenyetso cyerekana imiterere y'icyuma (III) complexometric. Gikoreshwa mu guhindura amatsinda ya guanidine muri poroteyine n'amatsinda ya amine muri poroteyine.

Ibisabwa mu kubika:

1. Irinde Minghuo kandi ushyiremo okisidasiyo ikomeye, funga hanyuma uzigame.

2. Bipfunyike mu ishashi ya pulasitiki cyangwa mu icupa rya pulasitiki mu icupa ry'icyuma; Ibikoresho bisanzwe bipfunyikwa: 200kg/ingoma. Birinda umuriro, ntibirinda umuriro, ntibirinda ubushuhe, bibikwa mu bubiko buteje akaga. Bika kandi bigatwarwa hakurikijwe amabwiriza agenga imiti ihumanya.
