Tus txheeb ze ceev yog 0.976, tus nqi luv nqi yog N20d1.4512.Cov acetone yog soluble hauv 8g dej, thiab nws yog tov nrog ethanol, benzene, chloroform, ether, acetone, thiab methampitic acid, thiab decomposed rau hauv acetone thiab acetic acid nyob rau hauv alkali tov.Thaum ua npaws kub, hluav taws kub thiab muaj zog oxidant, nws yog ib qho yooj yim ua rau hlawv.Tsis ruaj tsis khov hauv dej, yooj yim hydrolyzed rau hauv acetic acid thiab acetone.

Intermediate rau organic synthesis:

Acetylacetone yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis, dav siv hauv tshuaj, tshuaj tsw qab, tshuaj tua kab thiab lwm yam lag luam.

Acetone yog ib qho tseem ceeb raw khoom hauv kev lag luam tshuaj, xws li cov synthesis ntawm 4,6 - dimethylpyrimidine derivatives.Nws kuj yog siv los ua cov kuab tshuaj rau cellulose acetate, desiccant rau cov xim thiab cov kua roj vanish, thiab ib qho tseem ceeb analytical reagent.

Vim muaj cov ntawv enol, acetylacetone tuaj yeem tsim chelates nrog cobalt (Ⅱ), cobalt (Ⅲ), beryllium, txhuas, chromium, hlau (Ⅱ), tooj liab, npib tsib xee, palladium, zinc, indium, tin, zirconium, magnesium, manganese, scandium thiab thorium thiab lwm yam hlau ions, uas yuav siv tau los ua additives nyob rau hauv roj roj thiab lubricating roj.

Chemicalbook tuaj yeem siv los ua tus neeg saib xyuas cov hlau hauv micropores los ntawm nws cov chelation nrog cov hlau.Siv ua catalyst, resin crosslinking tus neeg saib xyuas, resin curing accelerator;Resin, roj hmab additives;Siv rau hydroxylation cov tshuaj tiv thaiv, hydrogenation cov tshuaj tiv thaiv, isomerization cov tshuaj tiv thaiv, tsis tshua muaj molecular unsaturated ketone synthesis thiab tsawg carbon olefin polymerization thiab copolymerization;Siv ua organic hnyav, siv rau cellulose acetate, number case, pigment;Xim kom qhuav tus neeg sawv cev;Cov khoom siv raw rau kev npaj tshuaj tua kab thiab fungicides, tsiaj tshuaj tua kab mob thiab pub additives;Infrared reflection iav, pob tshab conductive zaj duab xis (indium ntsev), superconducting zaj duab xis (indium ntsev) ua tus neeg sawv cev;Acetylacetone hlau complex muaj xim tshwj xeeb (tooj liab ntsev ntsuab, hlau ntsev liab, chromium ntsev ntshav) thiab insoluble hauv dej;Siv ua raw khoom rau tshuaj;Cov khoom siv hluavtaws hluavtaws.

Kev siv ntawm ACETYL ACETONE:

1. Pentanedione, tseem hu ua acetylacetone, yog qhov nruab nrab ntawm cov fungicides pyraclostrobin, azoxystrobin thiab cov tshuaj tua kab mob rimsulfuron.

2. Nws tuaj yeem siv los ua cov khoom siv raw thiab cov organic intermediates rau cov kws tshuaj, thiab tseem tuaj yeem siv los ua cov kuab tshuaj.

3. Siv los ua analytical reagent thiab extraction agent ntawm txhuas hauv tungsten thiab molybdenum.

4. Acetylacetone yog ib qho nruab nrab ntawm cov organic synthesis, thiab nws tsim cov amino-4,6-dimethylpyrimidine nrog guanidine, uas yog ib qho tseem ceeb ntawm cov tshuaj raw khoom.Nws tuaj yeem siv los ua cov kuab tshuaj rau cellulose acetate, ib qho ntxiv rau roj av thiab cov roj nplua nyeem, desiccant rau xim thiab kua roj vanish, fungicide, thiab tshuaj tua kab.Acetylacetone kuj tseem siv tau los ua cov khoom siv roj av tawg, hydrogenation thiab carbonylation cov tshuaj tiv thaiv, thiab oxidation accelerator rau oxygen.Nws tuaj yeem siv los tshem tawm cov hlau oxides hauv cov khoom ntxeem tau thiab kho polypropylene catalysts.Hauv cov teb chaws Europe thiab Asmeskas, ntau dua 50% yog siv rau hauv cov tsiaj nyeg tshuaj tua kab mob thiab cov khoom noj ntxiv.

5. Ntxiv rau cov yam ntxwv ntawm cov cawv thiab ketones, nws kuj pom cov xim liab tsaus nrog ferric chloride thiab cov ntaub ntawv chelates nrog ntau cov ntsev ntsev.Los ntawm acetic anhydride los yog acetyl chloride thiab acetone condensation, los yog los ntawm cov tshuaj tiv thaiv ntawm acetone thiab ketene tau.Chemicalbook yog siv los ua hlau extractant rau cais trivalent thiab tetravalent ions, xim thiab number case driers, tshuaj tua kab, tshuaj tua kab, fungicides, solvents rau siab polymers, reagents rau kev txiav txim ntawm thallium, hlau, fluorine, thiab organic synthesis intermediates.

6. Hloov cov hlau chelators.Colorimetric kev txiav txim siab ntawm hlau thiab fluorine, thiab kev txiav txim siab ntawm thallium nyob rau hauv lub xub ntiag ntawm carbon disulfide.

7. Fe(III) complexometric titration qhia;siv los hloov kho cov pab pawg guanidine (xws li Arg) thiab cov amino pawg hauv cov proteins.

8. Siv raws li kev hloov pauv hlau chelate tus neeg sawv cev;siv rau kev txiav txim colorimetric ntawm hlau thiab fluorine, thiab kev txiav txim siab ntawm thallium nyob rau hauv lub xub ntiag ntawm carbon disulfide.

9. Qhov taw qhia rau hlau (III) complexometric titration.Siv los hloov cov pab pawg guanidine hauv cov protein thiab cov amino pawg hauv cov proteins.

Cia tej yam kev mob:

1. Nyob deb ntawm Minghuo thiab muaj zog oxidant, foob thiab txuag.
