Lisebelisoa tsa ACETYL ACETONE:

1. Pentanedione, eo hape e tsejoang e le acetylacetone, ke karolo e bohareng ea li-fungicides pyraclostrobin, azoxystrobin le rimsulfuron ea herbicide.

2. E ka sebelisoa e le lisebelisoa tse tala le li-intermediate tsa organic bakeng sa meriana, hape e ka sebelisoa e le li-solvents.

3. E sebelisoa e le reagent ea tlhahlobo le moemeli oa ho ntša aluminium ka tungsten le molybdenum.

4. Acetylacetone ke karolo e bohareng ea motsoako oa 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 solvent bakeng sa cellulose acetate, setlatsetso sa peterole le mafura, desiccant bakeng sa pente le varnish, sebolaya-fungi le sebolaea likokoanyana.Acetylacetone e ka boela ea sebelisoa e le sesosa sa ho phatloha ha petroleum, hydrogenation le carbonylation reactions, le accelerator ea oxidation bakeng sa oksijene.E ka sebelisoa ho tlosa li-oxide tsa tšepe ka har'a lintho tse tiileng le ho phekola li-catalysts tsa polypropylene.Linaheng tsa Europe le Amerika, ho feta 50% ho sebelisoa litlhare tse thibelang letšollo le li-additives.

5. Ho phaella ho thepa e tloaelehileng ea lino tse tahang le ketone, e boetse e bontša 'mala o mofubelu o lefifi o nang le ferric chloride le ho etsa li-chelate tse nang le 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 motsoako oa tšepe ho arola li-ion tse trivalent le tetravalent, li-drier tsa pente le enke, chefo e bolaeang likokoanyana, chefo e bolaeang likokoanyana, li-fungicides, li-solvents bakeng sa li-polymers tse phahameng, li-reagents bakeng sa qeto ea thallium, tšepe, fluorine le li-organic synthesis intermediates.

6. Li-chelator tsa tšepe tsa phetoho.Qeto ea colorimetric ea tšepe le fluorine, le boikemisetso ba thallium boteng ba carbon disulfide.

7. Fe(III) complexometric titration indicator;e sebelisetsoang ho fetola lihlopha tsa guanidine (tse kang Arg) le lihlopha tsa amino liprotheine.

9. Letšoao la tšepe (III) complexometric titration.E sebelisetsoa ho fetola lihlopha tsa guanidine liprotheine le lihlopha tsa amino ka liprotheine.

Maemo a polokelo:

1. Lula hole le Minghuo le oxidant e matla, tiisa 'me u boloke.

2. E phuthele ka mokotleng oa polasetiki kapa moqomong oa polasetiki ka har'a moqomo oa tšepe;Sephutheloana se tloaelehileng sa sehlahisoa: 200kg/drum.Se ke keng sa chesoa, se sa cheng, se sa keneleng mongobo, se bolokoa sebakeng sa polokelo se kotsi.Ho boloka le ho tsamaisa ho latela melao ea lik'hemik'hale tse kotsi.
