ACETYL ACETONE(2,4 PENTANEDIONE)

Acetylacetone,e tsejoang hape e le 2, 4-pentadione, ke motsoako oa tlhaho, foromo ea lik'hemik'hale C5H8O2, mokelikeli o bonaletsang o se nang 'mala ho isa ho o mosehla hanyane, o qhibilihang hanyane ka metsing, 'me ethanol, ether, chloroform, acetone, ice acetic acid le li-solvents tse ling tsa tlhaho li kopantsoe, haholo-holo li sebelisoa e le solvent, moemeli oa ho ntša, li ka boela tsa sebelisoa ho lokiseng li-additives tsa peterole, litlolo, likokoanyana tse bolaeang likokoanyana tsa hlobo, chefo e bolaeang likokoanyana, lidae, jj.

Thepa:Acetone ha e na mmala kapa ke mokelikeli o ka tukang hanyane. Ntlha ea ho belisa ke 135-137 ° C, ntlha ea flash ke 34 ° C, 'me ntlha ea ho qhibiliha ke -23 ° C. Bongata bo amanang ke 0.976, sekhahla sa theolelo ke N20d1.4512. Acetone e qhibiliha ka har'a 8g ea metsi, 'me e kopantsoe le ethanol, benzene, chloroform, ether, acetone, le methampitic acid, 'me e bolisoa ho ba acetone le acetic acid ka har'a tharollo ea alkali. Ha ho tluoa tabeng ea feberu e phahameng, mollo o bobebe le oxidant e matla, ho bonolo ho baka ho chesa. Ha e tsitse ka metsing, e haelloa habonolo ho ba acetic acid le acetone.

Litšebeliso tsa ACETYL ACETONE：

1. Pentanedione, e tsejoang hape e le acetylacetone, ke karolo e bohareng ea pyraclostrobin, azoxystrobin le rimsulfuron ea sebolaya-dikokwana-hloko.

2. E ka sebelisoa e le thepa e tala le metsoako ea tlhaho bakeng sa meriana, 'me e ka boela ea sebelisoa e le li-solvent.

3. E sebelisoa e le sesebelisoa sa ho sekaseka le moemeli oa ho ntša aluminium ka har'a tungsten le molybdenum.

4. Acetylacetone ke karolo e bohareng ea tlhahiso ea lintho tse phelang, 'me e etsa amino-4,6-dimethylpyrimidine e nang le guanidine, e leng thepa ea bohlokoa ea meriana. E ka sebelisoa e le tharollo bakeng sa cellulose acetate, e eketsang peterole le mafura, desiccant bakeng sa pente le varnish, fungicide, le chefo e bolaeang likokoanyana. Acetylacetone e ka boela ea sebelisoa e le catalyst bakeng sa petsoho ea peterole, hydrogenation le carbonylation reactions, le oxidation accelerator bakeng sa oksijene. E ka sebelisoa ho tlosa li-oxide tsa tšepe linthong tse tiileng tse nang le masoba le ho phekola li-catalyst tsa polypropylene. Linaheng tsa Europe le Amerika, tse fetang 50% li sebelisoa meriana ea liphoofolo e loantšang letšollo le lijo tse ling.

5. Ntle le litšobotsi tse tloaelehileng tsa alcohols le ketones, e boetse e bonts'a 'mala o mofubelu o lefifi ka ferric chloride 'me e etsa chelates ka letsoai le lengata la tšepe. Ka acetic anhydride kapa acetyl chloride le acetone condensation, kapa ka karabelo ea acetone le ketene e fumanoeng. Chemicalbook e sebelisoa e le tšibollo ea tšepe ho arola li-ion tsa trivalent le tetravalent, li-dryer tsa pente le enke, chefo e bolaeang likokoanyana, chefo e bolaeang likokoanyana, fungicides, solvents bakeng sa li-polymer tse ngata, li-reagent bakeng sa ho fumana thallium, tšepe, fluorine, le li-intermediates tsa synthesis ea organic.

6. Li-chelator tsa tšepe tse fetohang. Ho fumana 'mala oa tšepe le fluorine, le ho fumana thallium ha ho na le carbon disulfide.

7. Sesupo sa titration sa Fe(III) complexometric; se sebediswa bakeng sa phetoho ya dihlopha tsa guanidine (tse kang Arg) le dihlopha tsa amino diprotheineng.
