Nā waiwai physicochemical:
1. ʻO ka wai kala ʻole a me ka dour hoʻonāukiuki.
2. Ka helu hehee 16.6 ℃;kahi e hoʻolapalapa ai 117.9 ℃;Kekahi uila: 39 ℃.
3. ʻAʻole hiki ke hoʻoheheʻe ʻia ka wai, ethanol, benzene a me ka ethyl ether, hiki ʻole ke hoʻoheheʻe ʻia i ka carbon disulphide.
Waihona:
1. Mālama ʻia i loko o kahi hale kūʻai ʻoluʻolu.
2. E mālama i ke ahi, wela.Pono ke kau anuanu e mālama i ka mahana ma mua o 16 DEG C, i mea e pale ai i ka paʻa.I ke kau anuanu, pono e mālama ʻia ka mahana ma luna o 16 DEG C i mea e pale aku ai i ka paʻa.
3. E hoʻopaʻa i ka pahu.Pono e hoʻokaʻawale ʻia mai ka oxidant a me ka alkali.Pono e pale ʻia ka hui ʻana ma nā ʻano a pau.
4. E hoʻohana i nā kukui pahū, nā keʻena ea.
5. ʻO nā mea hana mīkini a me nā mea hana e pāpā ai i ka hoʻohana ʻana i ka maʻalahi o ka hana ʻana i nā huna ahi.
6. Pono e ho'olako 'ia nā wahi e waiho ai me nā lako lā'au ulia pōpilikia a me nā lako hale kūpono.
E hoʻohana:
1.Derivative: Hoʻohana nui ʻia i ka synthetising acetic anhydride, acetic ether, PTA, VAC / PVA, CA, ethenone, chloroacetic acid, etc.
2.Pharmaceutical: Acetic acid e like me ka mea hoʻoheheʻe a me ka lāʻau lapaʻau, hoʻohana nui ʻia no ka hana ʻana o ka penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, a me sulfamethoxazole isoxazole, norfloxacin, ciprofloxacin, acetyl pnishenalic acid. ,caffeine, etc.
3.Intermediate: acetate , sodium hydrogen di ,ʻakika peracetic , etc
4.Destuff a me ka lole paʻi a me ka waihoʻoluʻu: Hoʻohana nui ʻia i ka hana ʻana i nā disperse dyes a me vat dyes, a me ka paʻi lole a me ka hana ʻana.
5. Synthesis ammonia: Ma ke ʻano o ka cuprammonia acetate, hoʻohana ʻia i ka hoʻomaʻemaʻe ʻana i nā syngas e wehe i kahi litl CO a me CO2
6. Kiʻi: Mea hoʻomohala
7. ʻO ke kopa maoli: Coagulant
8. ʻOihana hana: Kaohi ʻana i ka ʻuala mai ka paʻukū9.I ka addtin hoʻohana nui ʻia i ka mālama wai, syntheticfiber, pesticides, plastics, ʻili, pena, ka hana metala a me ka ʻoihana ʻoihana.
ʻIke pinepine ʻia ka waikawa acetic glacial.Hiki ke hoʻohana ʻia ka ʻakika glacial acetic solution no ka mālama ʻana i nā ʻano maʻi fungal ʻili, a me nā maʻi fungal nail.Ke hoʻohana ʻia ka ʻakika glacial acetic no ka mālama ʻana i nā maʻi fungal, hoʻohana mau ʻia kahi hopena 30% o ka waikawa acetic glacial.Hoʻohana ʻia ia e mālama i nā kui hina, hiki ke hoʻohana ʻia ma hope o ka hoʻomaʻemaʻe ʻana i nā kui maʻi a me ka lahilahi o nā kui.Hiki ke pale ʻia ka ʻili e pili ana i ke kui me kahi papa o ka petroleum jelly.I ka mālama ʻana i nā kulina a me nā warts ma ka ʻili, pono ʻoe e hoʻomaʻemaʻe i ka wahi maʻi ma mua o ka hoʻohana ʻana i ka lāʻau lapaʻau, e hoʻomoʻa i ka wai wela, a laila e kau i ka lāʻau.Pono e hoʻomaopopo ʻia no ka loaʻa ʻana o ka glacial acetic acid i kekahi hopena corrosive, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā maʻi fungal ma ka maka.I ka hoʻohana ʻana, e hoʻolohe pono i ka hoʻohui ʻana i ka lesion, ʻoi aku ka maikaʻi o nā ʻāpana ʻē aʻe o ka ʻili e hoʻopili i ka Vaseline e pale ai.
