ʻAsetila ʻasetona (2,4 Pentanedione)

ʻAsetilasetonaʻO 2,4-pentadione, kahi hui organik, ke ʻano kemika C5H8O2, ʻaʻohe kala a i ʻole ka melemele iki o ka wai, hoʻoheheʻe iki ʻia i ka wai, a me ka ethanol, ether, chloroform, acetone, ice acetic acid a me nā mea hoʻoheheʻe organik ʻē aʻe e hiki ke hoʻohuihui ʻia, hoʻohana nui ʻia e like me ka mea hoʻoheheʻe, mea hoʻopuka, hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana i nā mea hoʻohui gasoline, lubricants, mold insecticides, pesticides, dyes, etc.

Nā Waiwai:He wai ʻā ʻole ke kala a melemele iki paha ka Acetone. ʻO ke kiko paila he 135-137 ° C, ʻo ke kiko lapalapa he 34 ° C, a ʻo ke kiko heheʻe he -23 ° C. ʻO ka nui o ka mānoanoa he 0.976, ʻo ka helu hoʻēmi he N20d1.4512. Hiki ke hoʻoheheʻe ʻia ka acetone i loko o 8g o ka wai, a ua hui pū ʻia me ka ethanol, benzene, chloroform, ether, acetone, a me ka methampitic acid, a ua hoʻoheheʻe ʻia i loko o ka acetone a me ka acetic acid i loko o ka hopena alkali. I ka wā e pili ana i ke kuni kiʻekiʻe, ke ahi māmā a me ka oxidant ikaika, maʻalahi ke kuni. ʻAʻole paʻa i ka wai, maʻalahi ka hydrolyzed i loko o ka acetic acid a me ka acetone.

Waena no ka hoʻohuihui organik:

He mea koʻikoʻi ʻo Acetylacetone i ka synthesis organik, i hoʻohana nui ʻia i ka lāʻau lapaʻau, ka ʻala, ka pesticide a me nā ʻoihana ʻē aʻe.

He mea maka koʻikoʻi ka Acetone i ka ʻoihana lāʻau lapaʻau, e like me ka hana ʻana o nā 4,6 - dimethylpyrimidine derivatives. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea hoʻoheheʻe no ka cellulose acetate, kahi desiccant no nā pena a me nā varnish, a he mea hoʻohui loiloi koʻikoʻi.

Ma muli o ke ʻano o ka enol, hiki i ka acetylacetone ke hana i nā chelates me cobalt (Ⅱ), cobalt (Ⅲ), beryllium, alumini, chromium, hao (Ⅱ), keleawe, nickel, palladium, zinc, indium, tin, zirconium, magnesium, manganese, scandium a me thorium a me nā ion metala ʻē aʻe, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui i ka ʻaila wahie 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 kona chelation me nā metala. Hoʻohana ʻia ma ke ʻano he catalyst, resin crosslinking agent, resin curing accelerator; Resin, rubber additives; Hoʻohana ʻia no ka hydroxylation reaction, hydrogenation reaction, isomerization reaction, low molecular unsaturated ketone synthesis a me ka low carbon olefin polymerization a me ka copolymerization; Hoʻohana ʻia ma ke ʻano he organic solvent, hoʻohana ʻia no ka cellulose acetate, ink, pigment; Pena maloʻo pena; Nā mea maka no ka hoʻomākaukau ʻana i nā insecticides a me nā fungicides, nā lāʻau antidiarrheal holoholona a me nā mea hoʻohui hānai; ʻO ke aniani reflection infrared, ka ʻoniʻoni conductive moakaka (indium salt), superconducting film (indium salt) forming agent; Loaʻa i ka hui metala Acetylacetone kahi kala kūikawā (keleawe paʻakai ʻōmaʻomaʻo, hao paʻakai ʻulaʻula, chromium salt purple) a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai; Hoʻohana ʻia ma ke ʻano he mea maka no ka lāʻau lapaʻau; Nā mea synthetic organik.

Nā Hoʻohana o ACETYL ACETONE：

1. ʻO Pentanedione, i ʻike ʻia hoʻi ʻo acetylacetone, ʻo ia ka waena o nā fungicides pyraclostrobin, azoxystrobin a me ka herbicide rimsulfuron.

2. Hiki ke hoʻohana ʻia ma ke ʻano he mau mea maka a me nā mea waena organik no nā lāʻau lapaʻau, a hiki ke hoʻohana ʻia hoʻi e like me nā mea hoʻoheheʻe.

3. Hoʻohana ʻia e like me ka mea hoʻohui loiloi a me ka mea hoʻopuka o ka alumini i loko o ka tungsten a me ka molybdenum.

4. ʻO Acetylacetone kahi waena i ka synthesis organik, a hoʻokumu ia i ka amino-4,6-dimethylpyrimidine me guanidine, he mea maka lāʻau lapaʻau koʻikoʻi. Hiki ke hoʻohana ʻia ma ke ʻano he solvent no ka cellulose acetate, kahi mea hoʻohui no ka gasoline a me nā lubricants, kahi desiccant no ka pena a me ka varnish, kahi fungicide, a me kahi insecticide. Hiki ke hoʻohana ʻia ʻo Acetylacetone ma ke ʻano he mea hoʻoulu no ka haki ʻana o ka petroleum, hydrogenation a me nā hopena carbonylation, a me kahi mea hoʻonui oxidation no ka oxygen. Hiki ke hoʻohana ʻia e wehe i nā oxides metala i loko o nā mea paʻa porous a e mālama i nā mea hoʻoulu polypropylene. Ma 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 ke kala ʻulaʻula ʻeleʻele me ka ferric chloride a hana i nā chelates me nā paʻakai metala he nui. Ma o ka acetic anhydride a i ʻole acetyl chloride a me ka acetone condensation, a i ʻole ma o ka hopena o ka acetone a me ketene i loaʻa. Hoʻohana ʻia ʻo Chemicalbook ma ke ʻano he metala extractant e hoʻokaʻawale i nā ion trivalent a me tetravalent, nā mea hoʻomaloʻo pena a me ka ʻīnika, nā pesticides, nā pesticides, nā fungicides, nā solvents no nā polymers kiʻekiʻe, nā reagents no ka hoʻoholo ʻana o ka thallium, ka hao, ka fluorine, a me nā mea waena synthesis organik.

6. Nā chelators metala hoʻololi. Hoʻoholo kala o ka hao a me ka fluorine, a me ka hoʻoholo ʻana o ka thallium i ke alo o ka disulfide kalapona.

7. Hōʻailona titration complexometric Fe(III); hoʻohana ʻia no ka hoʻololi ʻana i nā hui guanidine (e like me Arg) a me nā hui amino i loko o nā protein.

8. Hoʻohana ʻia ma ke ʻano he mea hoʻohuihui metala hoʻololi; hoʻohana ʻia no ka hoʻoholo ʻana i ke kala o ka hao a me ka fluorine, a me ka hoʻoholo ʻana o ka thallium i ke alo o ka disulfide kalapona.

9. He hōʻailona no ka titration complexometric hao (III). Hoʻohana ʻia e hoʻololi i nā hui guanidine i loko o nā protein a me nā hui amino i loko o nā protein.

Nā kūlana mālama:

1. E noho mamao aku iā Minghuo a me ka oxidant ikaika, e sila a mālama.

2. E ʻōwili iā ia i loko o kahi ʻeke palaki a i ʻole ka pahu palaki i loko o ka pahu hao; ʻO ka hoʻopili huahana maʻamau: 200kg/pahu. Pale ahi, pale ahi, pale makū, mālama ʻia i loko o kahi hale kūʻai weliweli. Mālama a me ka lawe ʻana e like me nā lula o nā kemika weliweli.
