Kūwaena no ka hoʻohuihui organik:
He mea koʻikoʻi ka Acetylacetone i ka synthesis organik, hoʻohana nui ʻia i ka lāʻau lapaʻau, ʻala, pesticide a me nā ʻoihana ʻē aʻe.
He mea waiwai nui ka Acetone i ka ʻoihana lāʻau lapaʻau, e like me ka synthesis o 4,6 - dimethylpyrimidine derivatives.Hoʻohana ʻia ia ma ke ʻano he solvent no cellulose acetate, he desiccant no nā pena a me nā varnish, a me kahi reagent analytical koʻikoʻi.
Ma muli o ke ʻano o ka enol, hiki i ka acetylacetone ke hana i nā chelates me ka cobalt (Ⅱ), cobalt (Ⅲ), beryllium, aluminika, chromium, hao (Ⅱ), keleawe, nickel, palladium, zinc, indium, tin, zirconium, magnesium, manganese, scandium a me ka thorium a me nā mea metala ʻē aʻe, hiki ke hoʻohana ʻia e like me nā mea hoʻohui i ka ʻaila hinu a me ka ʻaila lubricating.
Hiki ke hoʻohana ʻia ka Chemicalbook ma ke ʻano he mea hoʻomaʻemaʻe no nā metala i loko o nā micropores ma o kāna chelation me nā metala.Hoʻohana ʻia e like me ka catalyst, resin crosslinking agent, resin curing accelerator;ʻO Resin, nā mea hoʻohui kino;Hoʻohana ʻia no ka hopena hydroxylation, hydrogenation reaction, isomerization reaction, low molecular unsaturated ketone synthesis and low carbon olefin polymerization and copolymerization;Hoʻohana ʻia e like me ka solvent organik, hoʻohana ʻia no ka cellulose acetate, inika, puaʻa;Mea hoʻomaloʻo pena;Nā mea waiwai no ka hoʻomākaukau ʻana i nā insecticides a me nā fungicides, nā lāʻau antidiarrheal holoholona a me nā mea hoʻohui hānai;ʻO ke aniani hoʻohālike infrared, ke kiʻiʻoniʻoni hoʻokalakupua (indium paʻakai), superconducting film (indium salt) mea hana;He waihoʻoluʻu kūikawā ko Acetylacetone metala (paʻakai keleawe ʻōmaʻomaʻo, paʻakai hao ʻulaʻula, chromium paʻakai poni) a hiki ʻole ke hoʻoheheʻe ʻia i ka wai;Hoʻohana ʻia ma ke ʻano he lāʻau lapaʻau;ʻO nā mea hana synthetic.
Nā noi o ACETYL ACETONE：
1. ʻO Pentanedione, i kapa ʻia ʻo acetylacetone, ʻo ia ka waena o nā fungicides pyraclostrobin, azoxystrobin a me ka herbicide rimsulfuron.
2. Hiki ke hoʻohana ʻia e like me nā mea maka a me nā mea waena kūlohelohe no nā lāʻau lapaʻau, a hiki ke hoʻohana ʻia e like me nā solvents.
3. Hoʻohana ʻia e like me ka analytical reagent a me ka extraction agent o ka alumini ma ka tungsten a me ka molybdenum.
4. ʻO ka Acetylacetone kahi mea waena i ka synthesis organik, a hana ia i ka amino-4,6-dimethylpyrimidine me ka guanidine, he mea waiwai nui ka lāʻau lapaʻau.Hiki ke hoʻohana ʻia e like me ka solvent no ka cellulose acetate, kahi mea hoʻohui no ka ʻaila a me nā lubricants, kahi desiccant no ka pena a me ka varnish, kahi fungicide, a me kahi insecticide.Hiki ke hoʻohana ʻia ka Acetylacetone ma ke ʻano he catalyst no ka petroleum cracking, hydrogenation a me carbonylation reactions, a me ka oxidation accelerator no ka oxygen.Hiki ke hoʻohana ʻia e hoʻoneʻe i nā ʻokikene metala i loko o nā mea paʻa porous a e mālama i nā catalyst polypropylene.I nā ʻāina ʻEulopa a me ʻAmelika, ʻoi aku ma mua o 50% i hoʻohana ʻia i nā lāʻau antidiarrheal holoholona a me nā mea hoʻohui hānai.
5. Ma waho aʻe o nā waiwai maʻamau o nā waiʻona a me nā ketones, hōʻike pū ia i ka ʻulaʻula ʻeleʻele me ka ferric chloride a hana i nā chelates me nā paʻakai metala he nui.Ma ka acetic anhydride a i ʻole acetyl chloride a me ka condensation acetone, a i ʻole ma ka hopena o ka acetone a me ka ketene i loaʻa.Hoʻohana ʻia ʻo Chemicalbook ma ke ʻano he metala extractant e hoʻokaʻawale i nā ion trivalent a me tetravalent, pena a me nā mea maloʻo inika, pesticides, pesticides, fungicides, solvents no nā polymers kiʻekiʻe, reagents no ka hoʻoholo ʻana o ka thallium, hao, fluorine, a me nā mea hoʻohui kūlohelohe.
6. Hoʻololi metala chelators.ʻO ka hoʻoholoʻana i ka hao a me ka fluorine, a me ka hoʻoholoʻana o ka thallium i mua o ka carbon disulfide.

8. Hoʻohana ʻia e like me transition metal chelating agent;hoʻohana ʻia no ka hoʻoholo ʻana i ka kala i ka hao a me ka fluorine, a me ka hoʻoholo ʻana o ka thallium i mua o ka carbon disulfide.
9. He hōʻailona no ka hao (III) complexometric titration.Hoʻohana ʻia e hoʻololi i nā hui guanidine i nā protein a me nā hui amino i nā protein.
Nā kūlana mālama:
1. E noho mamao mai Minghuo a me ka oxidant ikaika, sila a mālama.
2. E wahī i loko o ka ʻeke ʻeke a i ʻole ka pahu plastik i loko o ka pahu hao.Ka mālama ʻana a me ka lawe ʻana e like me nā hoʻoponopono o nā kemika weliweli.
