ACETYL ACETONE (2,4 PENTANEDIONE)

Acetylacetone,inozivikanwawo se2, 4-pentadione, imusanganiswa weorganic, makemikari fomura C5H8O2, mvura inoonekera isina ruvara kusvika yero zvishoma, inonyungudika zvishoma mumvura, uye ethanol, ether, chloroform, acetone, ice acetic acid nezvimwe zvinonyungudutsa organic zvinosanganiswa, zvinonyanya kushandiswa se solvent, extraction agent, zvinogonawo kushandiswa mukugadzira zvinowedzerwa papeturu, mafuta, zvipembenene zvemold, mishonga yezvipembenene, madhayi, nezvimwewo.

Zvivakwa:Acetone mvura isina ruvara kana kuti yero zvishoma inobvira moto. Poindi yekufashaira iri 135-137 ° C, poindi yekufuratira iri 34 ° C, uye poindi yekunyunguduka iri -23 ° C. Kuwanda kwechinhu ichi kuri 0.976, mwero wekudzikisira mutengo uri N20d1.4512. Acetone inonyungudika mu8g yemvura, uye inosanganiswa neethanol, benzene, chloroform, ether, acetone, uye methampitic acid, uye inoora kuita acetone neacetic acid mualkali solution. Kana zvasvika pakupisa kwakanyanya, moto mudiki uye oxidant yakasimba, zviri nyore kukonzera kupisa. Haina kugadzikana mumvura, inonyungudika nyore nyore kuita acetic acid neacetone.

Pakati pekugadzirwa kwezvinhu zvakasikwa:

Acetylacetone chinhu chakakosha mukugadzirwa kwezvinhu zvakasikwa, chinoshandiswa zvakanyanya mumishonga, kunhuhwirira, mishonga yezvipembenene nedzimwe nzvimbo.

Acetone chinhu chakakosha muindasitiri yemishonga, senge kugadzirwa kwe4,6 - dimethylpyrimidine derivatives. Inoshandiswawo se solvent ye cellulose acetate, desiccant yependi nema varnish, uye se analytical reagent inokosha.

Nekuda kwekuvapo kwechimiro cheenol, acetylacetone inogona kugadzira machelates ane cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aruminiyamu, chromium, iron (Ⅱ), copper, nickel, palladium, zinc, indium, tin, zirconium, magnesium, manganese, scandium uye thorium nedzimwe ions dzesimbi, dzinogona kushandiswa sekuwedzera mumafuta emafuta nemafuta ekuzora.

Bhuku reChemicalbook rinogona kushandiswa semushonga wekuchenesa simbi dziri muma micropores nekuda kwechelation yaro nesimbi. Rinoshandiswa se catalyst, resin crosslinking agent, resin curing accelerator; Resin, zvinowedzerwa zverabha; Rinoshandiswa pakuita hydroxylation reaction, hydrogenation reaction, isomerization reaction, low molecular unsaturated ketone synthesis uye low carbon olefin polymerization uye copolymerization; Rinoshandiswa se organic solvent, rinoshandiswa pa cellulose acetate, inki, pigment; Pendi drying agent; Zvinhu zvisina kugadzirwa zvekugadzira zvipembenene nefungicides, mishonga yekurwisa manyoka nezvinowedzerwa zvekudya; Girazi re infrared reflection, transparent conductive film (indium salt), superconducting film (indium salt) forming agent; Acetylacetone metal complex ine ruvara rwakakosha (copper salt green, iron salt red, chromium salt purple) uye isinganyungudike mumvura; Rinoshandiswa sezvinhu zvisina kugadzirwa zvemishonga; Organic synthetic materials.

Mashandisirwo eACETYL ACETONE：

1. Pentanedione, inozivikanwawo seacetylacetone, ndiyo mushonga wepakati wefungicides pyraclostrobin, azoxystrobin uye rimsulfuron yemishonga inouraya utachiona.

2. Inogona kushandiswa sezvinhu zvakagadziriswa uye sezvinhu zvemukati zvemishonga, uye inogona kushandiswawo sezvinonyungudutsa.

3. Inoshandiswa semushonga wekuongorora uye mumiririri wekubvisa aruminiyamu mu tungsten ne molybdenum.

4. Acetylacetone imhando yepakati mukugadzirwa kwezvinhu zvipenyu, uye inoumba amino-4,6-dimethylpyrimidine ine guanidine, inova chinhu chakakosha mumishonga. Inogona kushandiswa semushonga we cellulose acetate, chinhu chinowedzera peturu nemafuta, desiccant yependi ne varnish, mushonga wefungi, uye mushonga wezvipembenene. Acetylacetone inogonawo kushandiswa semushonga wekubvisa peturu, hydrogenation ne carbonylation reactions, uye mushonga we oxidation we oxygen. Inogona kushandiswa kubvisa metal oxides muzvinhu zvine porous solids uye kurapa polypropylene catalysts. Munyika dzeEurope neAmerica, anopfuura 50% anoshandiswa mumishonga yekudzivirira manyoka nezvikafu zvemhuka.

5. Kuwedzera kune hunhu hwealcohols nemaketones, inoratidzawo ruvara rutsvuku rwakasviba neferric chloride uye inoumba chelates ine munyu wesimbi yakawanda. Ne acetic anhydride kana acetyl chloride uye acetone condensation, kana nekuita kwe acetone ne ketene yakawanikwa. Chemicalbook inoshandiswa sesimbi inoburitsa kupatsanura maion matatu netetravalent, pendi ne ink driers, mishonga yezvipembenene, mishonga yezvipembenene, fungicides, solvents yemapolymers akawanda, reagents dzekuongorora thallium, iron, fluorine, uye organic synthesis intermediates.

6. Transition metal chelators. Kuongororwa kwesimbi nefluorine neruvara rwemavara, uye kuongororwa kwethallium kana paine carbon disulfide.

7. Chiratidzo cheFe(III) complexometric titration; chinoshandiswa pakushandura mapoka eguanidine (akadai seArg) uye mapoka eamino mumapuroteni.

8. Inoshandiswa semushonga wekuchinja simbi; inoshandiswa pakuona simbi nefluorine zvine ruvara, uye pakuona thallium kana paine carbon disulfide.

9. Chiratidzo che titration yesimbi (III) complexometric. Chinoshandiswa kugadzirisa mapoka eguanidine mumapuroteni uye mapoka emaamino mumapuroteni.

Mamiriro ekuchengetedza:

1. Gara kure neMinghuo uye chengetedza oxidant yakasimba, vhara wochengetedza.

2. Putira mubhegi repurasitiki kana mudhiramu repurasitiki mudhiramu resimbi; Kurongedza kwechigadzirwa kwakajairika: 200kg/dhiramu. Haitsvi, haitsvi, hainyoro, inochengetwa mudura rine njodzi. Kuchengeta nekutakura zvinoenderana nemitemo yemakemikari ane njodzi.
