1.White a i ʻole melemele liʻiliʻi wai aniani me ka ʻala ʻala. Hiki i ka wai; ethanol; ka etera a me ka chloroform, etc., paʻa ʻole, decomposed i ka wā e launa pū ai me ka alkali a i ʻole i hoʻoheheʻe ʻia ma ke kaomi ea. ʻAʻole paʻa, decomposes i ka wā e launa pū ai me ka alkali a i ʻole ka distilled ma ke kaomi o ka lewa.
2. ʻO ka huahana he haʻahaʻa haʻahaʻa, ʻaʻole ʻae ʻia ka ʻai ʻana i ka huahana, pono ka mea hana e hoʻokomo i nā mea pale.
3. Nā waiwai kemika: Loaʻa i ka waiʻona Diacetone ka carbonyl a me ka hydroxyl i loko o ka mole, me nā waiwai ketone o ketone a me ka waiʻona tertiary. Hana ʻia ka decomposition i ka wā i wela ai i 130°C a i luna aʻe me ka alkali, e hana ana i 2 mau mole acetone. Ke hoʻomehana ʻia me ka sulfuric acid a i ʻole ka nui o ka iodine, maloʻo ia e hana i ka isopropylidene acetone. ʻO ka pilina me ka sodium hypobromite e hoʻopuka i ka 2-hydroxyisovaleric acid. Hoʻokumu ka hydrogenation Catalytic i ka 2-methyl-2,4-pentanediol.
4. ʻO kēia huahana e hoʻonāukiuki i nā maka, kaʻili a me nā mucous membrane o ka'ōpū hanu. Komo ia i loko o ke kino ma o ka hanu a me ka digestive tract, e pili ana i ka ʻōnaehana nerve a hoʻopōʻino i ke ake a me ka ʻōpū. Hiki i ka inhalation o ka mahu kiʻekiʻe ke hana i ka edema pulmonary a hiki i ka coma. Hiki i ka ʻike lōʻihi ke alakaʻi i ka dermatitis.

Hoʻohana huahana:
1. Hiki ke hoʻohanaʻia ka waiʻona Diacetone ma keʻano he mea hoʻomaʻemaʻe metala, mālama lāʻau, mālama no ke kiʻi paʻi kiʻi a me nā lāʻau lapaʻau, antifreeze, solvent no nā wai hydraulic, extractant a me ka fiber finishing agent.
2. Hoʻohana nuiʻia ka waiʻona Diacetone e like me ka mea hoʻoheheʻe no nā peʻa electrostatic spray, celluloid, nitrocellulose, nā momona, nāʻaila, nā waxes a me nā resins. ʻO ka waiʻona diacetone kahi mea hoʻoheheʻe organik kiʻekiʻe. He haʻahaʻa ka viscosity a he liʻiliʻi ka hopena o ka mahana ma luna o ka viscosity. Hoʻohana ʻia e like me ka mea hoʻoheheʻe a me ka pena pena no ka pena cellulose ester, ka inika paʻi, ka pena resin synthetic etc.
3. Hoʻohana nui ʻia ma ke ʻano he mea hoʻoheheʻe no ka resins, electrostatic spray paints, celluloid, nitro fibers, nā momona, nā aila a me nā waxes. Hoʻohana ʻia ʻo ia ma ke ʻano he mea hoʻomaʻemaʻe metala, mālama lāʻau, mālama no ke kiʻi paʻi kiʻi a me ka lāʻau lapaʻau, antifreeze, hydraulic oil solvent, extractant a me nā mea hoʻopau fiber. ʻO ia kekahi ʻano o nā mea hoʻohuihui organik.
4.Cosmetic solvent, hoʻohana nui ʻia e like me ka nail polish a me nā mea hoʻonaninani ʻē aʻe o ka mea hoʻolapalapa kiʻekiʻe. Hoʻopili pinepine ʻia me nā mea hoʻoheheʻe haʻahaʻa haʻahaʻa a me nā mea hoʻoheheʻe waena i loko o nā mea hoʻoheheʻe hui ʻia, i mea e loaʻa ai ka helu evaporation kūpono a me ka viscosity.
Nā memo mālama huahana:
1. E kūʻai i loko o kahi hale kūʻai ʻoluʻolu.
2. E mālama i ke ahi a me ke kumu wela, e pale i ka lā pololei.
3. E hoʻopaʻa i ka pahu.
4. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka metala, a hiki ke mālama ʻia i loko o ka hao, ke kila palupalu a i ʻole nā pahu alumini, akā he hopena erosive ma nā ʻano plastics.
5. E kūʻai a lawe i kahi kaʻawale mai nā mea oxidizing a me nā waikawa.
6. Hoʻopili ʻia ka bakeke hao a i ʻole ka ʻōmole aniani me ka pahu lāʻau.
