Mugadziri Mutengo Wakanaka ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

tsananguro pfupi:

ACETYL ACETONE, inozivikanwawo se diacetylmethane, pentamethylene dione, inobva mu acetone, molecular formula CH3COCH2COCH3, mvura inopenya isina ruvara kusvika yero yakajeka. ACETYL ACETONE inowanzova musanganiswa we tautomers mbiri, enol ne ketone, dziri mu dynamic equilibrium. Enol Chemicalbook isomers dzinoumba hydrogen bonds mu molecule. Mumusanganiswa, keto inokwana 18%, uye alkenes Alcohol form inokwana 82%. Musanganiswa we petroleum ether wemusanganiswa wakatonhodzwa kusvika -78°C, uye enol form yakamiswa se solid, zvekuti zviviri zvakaparadzaniswa; iyo enol form payakadzokera ku room temperature, ACETYL ACETONE yakabva yangoerekana yava mu equilibrium state iri pamusoro apa.

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.
