Properties:Acetone haina ruvara kana kuti yero zvishoma inobvira mvura.Nzvimbo yekubikira ndeye 135-137 ° C, iyo flash point ndeye 34 ° C, uye nzvimbo yakanyunguduka ndeye -23 ° C. Kuwanda kwehuwandu ndeye 0.976, chiyero chekudzikisa ndiN20d1.4512.Acetone inonyungudika mu8g yemvura, uye inosanganiswa ne ethanol, benzene, chloroform, ether, acetone, uye methampitic acid, uye inowora kuita acetone neacetic acid mumushonga wealkali.Kana zvasvika kune high fever, light fire uye yakasimba oxidant, zviri nyore kukonzera kupisa.Kusagadzikana mumvura, nyore hydrolyzed kuita acetic asidhi uye acetone.
Yepakati kune organic synthesis:
Acetylacetone yakakosha yepakati mune organic synthesis, inoshandiswa zvakanyanya mumishonga, kunhuhwirira, mushonga wezvipembenene uye mamwe maindasitiri.
Acetone chinhu chakakosha mbishi muindasitiri yemishonga, senge synthesis ye4,6 - dimethylpyrimidine derivatives.Inoshandiswawo se solvent ye cellulose acetate, desiccant yependi uye varnishes, uye yakakosha yekuongorora reagent.
Nekuda kwekuvapo kweanol fomu, acetylacetone inogona kugadzira chelates ine cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminium, chromium, iron (Ⅱ), mhangura, nickel, palladium, zingi, indium, tin, zirconium, magnesium, manganese, scandium uye thorium nedzimwe simbi ions, iyo inogona kushandiswa sekuwedzera mumafuta emafuta uye mafuta ekuzora.
Iyo Chemicalbook inogona kushandiswa seyekuchenesa simbi mumamicropores neiyo chelation ine simbi.Inoshandiswa se catalyst, resin crosslinking agent, resin kuporesa accelerator;Resin, rubber additives;Inoshandiswa ku hydroxylation reaction, hydrogenation reaction, isomerization reaction, low molecular unsaturated ketone synthesis uye low carbon olefin polymerization uye copolymerization;Inoshandiswa se organic solvent, inoshandiswa kune cellulose acetate, inki, pigment;Paint drying agent;Raw zvinhu zvekugadzirira kwezvipembenene uye fungicides, mhuka antidiarrheal zvinodhaka uye zvekudya zvinowedzera;Infrared reflection glass, transparent conductive film (indium salt), superconducting film (indium salt) kugadzira agent;Acetylacetone metal complex ine ruvara rwakakosha (copper munyu yakasvibirira, iron munyu mutsvuku, chromium munyu yepepuru) uye isinganyungudika mumvura;Inoshandiswa sezvigadzirwa zvemishonga;Organic synthetic zvinhu.
Zvishandiso zveACETYL ACETONE:
1. Pentanedione, inozivikanwawo seacetylacetone, ndiyo yepakati yefungicides pyraclostrobin, azoxystrobin uye herbicide rimsulfuron.
2. Inogona kushandiswa seyakagadziriswa uye organic intermediates yemishonga, uye inogona kushandiswa sezvinonyungudutsa.
3. Inoshandiswa seanalytical reagent uye inobvisa aluminium mu tungsten uye molybdenum.
4. Acetylacetone inhengo yepakati mune organic synthesis, uye inoumba amino-4,6-dimethylpyrimidine ne guanidine, iyo inokosha yemishonga yakasvibiswa.Inogona kushandiswa se solvent ye cellulose acetate, chinowedzera peturu uye mafuta ekuzora, desiccant yepende uye varnish, fungicide, uye mushonga wezvipembenene.Acetylacetone inogonawo kushandiswa sechinhu chinokonzera petroleum kupaza, hydrogenation uye carbonylation reactions, uye oxidation accelerator yeokisijeni.Inogona kushandiswa kubvisa simbi oxides mune porous solids uye kurapa polypropylene catalysts.Munyika dzeEurope neAmerica, anopfuura makumi mashanu muzana anoshandiswa mumishonga yezvipfuyo antidiarrheal uye zvekudya zvinowedzera.
5. Mukuwedzera kune zvakajairwa zvinhu zvedoro uye ketoni, inoratidzawo rima dzvuku ruvara neferric chloride uye inoumba chelates nesimbi yakawanda yemunyu.Neacetic anhydride kana acetyl chloride uye acetone condensation, kana nekuita kweacetone uye ketene yakawanikwa.Chemicalbook inoshandiswa sesimbi inobvisa kuparadzanisa trivalent uye tetravalent ion, pendi neingi driers, mishonga yezvipembenene, mishonga yezvipembenene, fungicides, zvinonyungudutsa zvemapolymers akakwira, mareagents ekutemerwa kwethallium, iron, fluorine, uye organic synthesis intermediates.
6. Shanduko yesimbi chelators.Colorimetric kutsunga kwesimbi uye fluorine, uye kutsunga kwethallium pamberi pekabhoni disulfide.
7. Fe (III) complexometric titration indicator;inoshandiswa kugadzirisa mapoka e guanidine (akadai seArg) uye mapoka emamino mumapuroteni.
8. Inoshandiswa seshanduko yesimbi chelating agent;inoshandiswa pakusarudza colorimetric yesimbi uye fluorine, uye kutsunga kwethallium pamberi pekabhoni disulfide.
9. Chiratidzo chesimbi (III) complexometric titration.Inoshandiswa kushandura guanidine mapoka mumapuroteni uye mapoka emamino mumapuroteni.
Mamiriro ekuchengetera:
1. Gara kure neMinghuo uye yakasimba oxidant, chisimbiso uye chengetedza.
2. Iputire mubhegi repurasitiki kana dhiramu resimbi mudhiramu resimbi;Zvakarongedzerwa zvechigadzirwa:200kg/drum.Isingatsvaki moto, isingapisi,inodzivirira hunyoro, inochengetwa mudura rine njodzi.Kuchengetedza uye kutakura maererano nemirairo yemakemikari ane ngozi.
