I-ACETYL ACETONE(2,4 PENTANEDIONE)

I-acetylacetone,ekwaziwa ngokuba yi-2, 4-pentadione, yikhompawundi ephilayo, ifomula yekhemikhali C5H8O2, engenambala ukuya kulwelo olumthubi olucacileyo, lunyibilika kancinane emanzini, kunye ne-ethanol, i-ether, i-chloroform, i-acetone, i-acetic acid kunye nezinye izinyibilikisi eziphilayo ezixubileyo, ezisetyenziswa kakhulu njenge-solvent, i-extraction agent, i-agent agent enokusetyenziswa, i-lunglease inokusetyenziswa, amayeza okubulala izinambuzane, izitshabalalisi, iidayi, njl.

Iinkcazelo ngeempawu:IAcetone lulwelo olungenambala okanye lutyheli kancinane olunokutsha. Indawo yokubilisa yi-135-137 ° C, i-flash point yi-34 ° C, kwaye i-melting point -23 ° C. Ubuninzi obusondeleyo ngu-0.976, izinga lokunciphisa ngu-N20d1.4512. I-acetone inyibilika kwi-8g yamanzi, kwaye ixutywe ne-ethanol, ibenzene, i-chloroform, i-ether, i-acetone, kunye ne-methampitic acid, kwaye ibolile ibe yi-acetone kunye ne-acetic acid kwisisombululo se-alkali. Xa kuziwa kumkhuhlane ophezulu, umlilo okhanyayo kunye ne-oxidant enamandla, kulula ukubangela ukutshisa. Ukungazinzi emanzini, ngokulula i-hydrolyzed kwi-acetic acid kunye ne-acetone.

Esiphakathi kwi-organic synthesis:

I-acetylacetone yinto ebalulekileyo ephakathi kwi-organic synthesis, esetyenziswa ngokubanzi kwiyeza, ivumba, i-pesticide kunye namanye amashishini.

I-acetone iyinto ebalulekileyo ekrwada kwishishini lamachiza, njenge-synthesis ye-4,6 - i-dimethylpyrimidine derivatives. Ikwasetyenziswa njenge-solvent ye-cellulose acetate, i-desiccant yeepeyinti kunye ne-varnishes, kunye ne-reagent ebalulekileyo yohlalutyo.

Ngenxa yobukho befom enol, i-acetylacetone inokwenza i-chelates kunye ne-cobalt (Ⅱ), i-cobalt (Ⅲ), i-beryllium, i-aluminium, i-chromium, isinyithi (Ⅱ), ubhedu, i-nickel, i-palladium, i-zinc, i-indium, i-tin, i-zirconium, i-magnesium, i-manganese, i-candium esetyenzisiweyo njenge-oyile kunye ne-thorium esetyenzisiweyo kunye ne-fuel bery ioli yokuthambisa.

I-Chemicalbook ingasetyenziselwa njenge-agent yokucoca isinyithi kwii-micropores nge-chelation yayo ngeentsimbi. Isetyenziswe njenge-catalyst, i-resin crosslinking agent, i-resin yokunyanga i-accelerator; I-resin, izongezo zerabha; Isetyenziselwa ukusabela kwe-hydroxylation, i-hydrogenation reaction, i-isomerization reaction, i-molecular unsaturated ketone synthesis kunye ne-carbon olefin polymerization ephantsi kunye ne-copolymerization; Isetyenziswe njenge-solvent ye-organic, esetyenziselwa i-cellulose acetate, inki, i-pigment; I-agent yokomisa ipeyinti; Izinto ezisetyenziselwa ukulungiswa kwezinambuzane kunye nefungicides, iziyobisi zezilwanyana ezilwa norhudo kunye nezongezo zokutya; Iglasi ebonisa i-infrared, ifilimu ye-transparent conductive (ityuwa ye-indium), ifilimu ye-superconducting (ityuwa ye-indium) eyenza i-agent; I-acetylacetone metal complex inombala okhethekileyo (ityuwa yobhedu eluhlaza, ityuwa yentsimbi ebomvu, ityuwa ye-chromium emfusa) kwaye ayinyibiliki emanzini; Isetyenziswa njengezinto ekrwada amayeza; Izinto zokwenziwa kwezinto eziphilayo.

Usetyenziso lwe-ACETYL ACETONE:
