Nā waiwai huahana:
1. Kemimi Pono: Butanone hiki ke maʻalahi i nā ʻano like ʻole ma muli o kāna hui carbonyl a me ka hydrogen hana e pili ana i ka hui carbonyl. Hana ʻia ka condensation i ka wā i wela ai me ka waikawa hydrochloric a i ʻole ka sodium hydroxide e hana ai i 3,4-dimethyl-3-hexen-2-one a i ʻole 3-methyl-3-hepten-5-one. Ke ʻike ʻia i ka lā no ka manawa lōʻihi, hoʻokumu ʻia ka ethane, acetic acid a me nā huahana condensation. Ke hoʻoneʻe ʻia me ka waikawa nitric, hana ʻia ka biacetyl. Ke hoʻoheheʻe ʻia me ka waikawa chromic a me nā mea hoʻoneʻe ikaika ʻē aʻe, hana ʻia ka acetic acid. Paʻa ka Butanone i ka wela, ma luna o 500°Cka pohā wela e hoʻohua i ka alkenone a i ʻole methyl alkenone. Ke condensed me aliphatic a aromatic aldehydes, hana ia kiʻekiʻe molecular kaumaha ketones, cyclic pūhui, ketones a me resins, etc. No ka laʻana, i ka condensed me formaldehyde i mua o ka sodium hydroxide, hana ia bi-acetyl. No ka laʻana, ka condensation me formaldehyde i mua o ka sodium hydroxide e hoʻopuka mua i ka 2-methyl-1-butanol-3-one a laila dehydrates e hana i ka methylisopropenyl ketone. Hoʻopili ʻia kēia pūhui ke ʻike ʻia i ka lā a i ʻole ke kukui ultraviolet. ʻO ka condensation me ka phenol e hana i ka 2,2-bis(4-hydroxyphenyl)butane. Hoʻopili me nā esters aliphatic i mua o kahi catalyst kumu e hana i nā β-diketones. Acylation me ka anhydride i mua o kahi mea hoʻoheheʻe ʻakika e hana i ka β-diketone. ʻO ka pane me ka hydrogen cyanide e hana i ka cyanohydrin. Hoʻopili me ka ammonia e hana i nā derivatives ketopiperidine. Hoʻololi koke ʻia ka α-hydrogen atom o butanone me nā halogens e hana i nā ketone halogenated like ʻole, e laʻa, 3-chloro-2-butanone me ka chlorine. Hoʻopuka ka pilina me 2,4-dinitrophenylhydrazine melemele 2,4-dinitrophenylhydrazone (mp 115 ° C).

Hoʻohana huahana:
Hoʻohana nui ʻia ʻo 1.Butanone ma ke ʻano he mea hoʻoheheʻe, e like me ka lubricating oil dewaxing, ka ʻoihana pena a me nā ʻano mea hoʻoheheʻe resin, ke kaʻina ʻaila ʻaila a me ka hoʻomaʻemaʻe ʻana o ka azeotropic distillation.
ʻO 2.Butanone ka hoʻomākaukau ʻana i nā lāʻau lapaʻau, dyes, detergents, nā mea ʻala, antioxidants a me kekahi mau catalysts he intermediates, synthetic anti-desiccant agent methyl ethyl ketone oxime, polymerisation catalyst methyl ethyl ketone peroxide, etching inhibitor methyl pentynol, etc., i loko o ka ʻoihana uila ma ke ʻano he photolithography o nā kaapuni i hoʻohui ʻia ma hope o ka mea hoʻomohala.
3. Hoʻohana ʻia e like me ka mea holoi, lubricant dewaxing agent, vulcanisation accelerator a me nā mea waena.
4.Hoʻohana i ka synthesis organik. Hoʻohana ʻia e like me ka chromatographic analysis mea maʻamau a me ka solvent.
5.Hoʻohana ʻia i ka ʻoihana uila, hoʻohana mau ʻia e like me ka hoʻomaʻemaʻe a me ka degreasing agent.
6. Ma waho aʻe o ka hoʻohana nuiʻia i ka hoʻomaʻemaʻeʻana i kaʻaila, nā uhi, nā mea kōkua, nā mea hoʻopili, nā meaʻulaʻula, nā lāʻau lapaʻau a me nā mea uila e hoʻomaʻemaʻe, a me nā mea'ē aʻe, hoʻohana nuiʻia e like me ka solvent no ka nitrocellulose, vinyl resin, acrylic resin a me nā resins synthetic. ʻO kāna mau mea maikaʻi ʻo ka solubility ikaika a me ka volatility haʻahaʻa ma mua o ka acetone. I ka ʻohi ʻana i nā aila mea kanu, ka hoʻomaʻemaʻe ʻana o ka azeotropic distillation a me ka hoʻomākaukau ʻana i nā mea ʻala, antioxidants a me nā noi ʻē aʻe.
7. He mea maka no ka synthesis organik a hiki ke hoʻohana ʻia e like me ka solvent. I loko o kaʻoihana hoʻomaʻemaʻeʻaila no ka lubricating oil dewaxing agent, oiai hoʻohanaʻia i ka lāʻau lapaʻau, ka pena, nā meaʻono, nā meaʻala, nā meaʻala a me nā mea uila a me nāʻoihana'ē aʻe. Mea hoʻoheheʻe no ka ʻīnika wai. Hoʻohana ʻia i nā mea hoʻonaninani no ka hana ʻana i ka nail polish, ma ke ʻano he mea hoʻoheheʻe haʻahaʻa haʻahaʻa, hiki ke hōʻemi i ka viscosity o ka nail polish, ka maloʻo wikiwiki.
8.Hoʻohanaʻia e like me ka solvent, dewaxing agent, i hoʻohanaʻia hoʻi i ka synthesis organik, a ma keʻano he kumu waiwai no nā meaʻala a me nā lāʻau lapaʻau.
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.
3.ʻAʻole pono eʻoi aku ka mahana o ka mālamaʻana37°C.
4. E hoʻopaʻa i ka pahu.
5. Pono e mālama kaʻawale ʻia mai nā mea oxidizing,nā mea hoʻemi a me nā alkalis,aole pono e huikau.
6.E hoʻohana i nā kukui pahū-hōʻoia a me nā pono ea.
7. Hoʻopaʻa i ka hoʻohana ʻana i nā mea hana mīkini a me nā mea hana maʻalahi e hoʻohua i nā huna huna.
8. Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia a me nā mea hoʻomaha kūpono.
