Chaw Tsim Khoom Zoo Nqe ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

piav qhia luv luv:

ACETYL ACETONE, tseem hu ua diacetylmethane, pentamethylene dione, yog ib qho derivative ntawm acetone, molecular formula CH3COCH2COCH3, tsis muaj xim rau lub teeb daj pob tshab kua. ACETYL ACETONE feem ntau yog ib qho sib tov ntawm ob tug tautomers, enol thiab ketone, uas nyob rau hauv dynamic equilibrium. Enol Chemicalbook isomers tsim hydrogen bonds hauv lub molecule. Hauv qhov sib tov, keto suav txog li 18%, thiab alkenes Cawv daim ntawv suav rau 82%. Cov roj av ether kua ntawm qhov sib tov tau txias rau -78 ° C, thiab daim ntawv enol tau precipitated ua ib qho khoom khov, yog li ntawd ob qho tib si tau sib cais; thaum daim ntawv enol rov qab mus rau chav tsev kub, ACETYL ACETONE tau cia li nyob rau hauv lub xeev sib npaug saum toj no.

Cov Lus Txhais: acetyl; Acetyl2-propanone; acetyl-2-propanon; acetyl2-propanone; acetyl-aceton; CH3COCH2COCH3; pentan-2,4-dione; Pentanedione

Cov ntawv thov ntawm ACETYL ACETONE

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

2. Nws siv tau ua cov khoom siv raw thiab cov organic intermediates rau cov tshuaj, thiab kuj siv tau ua cov kuab tshuaj.

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

4. Acetylacetone yog ib qho nruab nrab hauv kev tsim cov organic, thiab nws tsim cov amino-4,6-dimethylpyrimidine nrog guanidine, uas yog cov khoom siv tshuaj tseem ceeb. Nws tuaj yeem siv ua cov kuab tshuaj rau cellulose acetate, ib qho khoom ntxiv rau roj av thiab cov roj nplua nyeem, ib qho desiccant rau xim thiab varnish, ib qho fungicide, thiab ib qho tshuaj tua kab. Acetylacetone kuj tseem siv tau ua ib qho catalyst rau kev tawg roj av, hydrogenation thiab carbonylation reactions, thiab ib qho oxidation accelerator rau oxygen. Nws tuaj yeem siv los tshem tawm cov hlau oxides hauv cov khoom khov thiab kho cov polypropylene catalysts. Hauv cov tebchaws European thiab Asmeskas, ntau dua 50% yog siv rau hauv cov tshuaj tua kab mob tsiaj txhu thiab cov khoom noj pub.

5. Ntxiv rau cov khoom siv ntawm cov cawv thiab ketones, nws kuj qhia txog xim liab tsaus nrog ferric chloride thiab tsim cov chelates nrog ntau cov ntsev hlau. Los ntawm acetic anhydride lossis acetyl chloride thiab acetone condensation, lossis los ntawm cov tshuaj tiv thaiv ntawm acetone thiab ketene tau txais. Chemicalbook siv los ua cov hlau extractant los cais cov trivalent thiab tetravalent ions, xim thiab kua mem qhuav, tshuaj tua kab, tshuaj tua kab, fungicides, cov kuab tshuaj rau cov polymers siab, reagents rau kev txiav txim siab ntawm thallium, hlau, fluorine, thiab organic synthesis intermediates.

6. Cov tshuaj chelators hloov pauv hlau. Kev txiav txim siab xim ntawm hlau thiab fluorine, thiab kev txiav txim siab ntawm thallium nyob rau hauv qhov muaj carbon disulfide.

7. Fe (III) complexometric titration indicator; siv rau kev hloov kho ntawm guanidine pawg (xws li Arg) thiab amino pawg hauv cov proteins.

8. Siv ua tus neeg sawv cev hloov pauv hlau chelating; siv rau kev txiav txim siab xim ntawm hlau thiab fluorine, thiab kev txiav txim siab ntawm thallium nyob rau hauv qhov muaj carbon disulfide.

9. Ib qho cim qhia txog kev ntsuas hlau (III) complexometric titration. Siv los hloov cov pab pawg guanidine hauv cov protein thiab cov pab pawg amino hauv cov protein.
