Nā waiwai physicochemical:
1. ʻO ka wai kala ʻole a me ka dour hoʻonāukiuki.
2. Ka helu hehee 16.6 ℃; wahi paila 117.9 ℃; Kaila uila: 39 ℃.
3. ʻAʻole hiki ke hoʻoheheʻe ʻia ka wai, ethanol, benzene a me ka ethyl ether, hiki ʻole ke hoʻoheheʻe ʻia i loko o 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 ai a pale 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, non-acetyl salicydine. ,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.
ʻO ka waikawa acetic, i ʻike ʻia he acetic acid (36% -38%), glacial acetic acid (98%), ka mea hoʻoheheʻe kemika CH3COOH, he waika monic organik, ka mea nui o ka vīneka. ʻO ka ʻakika anhydrous acetic maʻemaʻe (glacial acetic acid) he paʻa hygroscopic kala ʻole me kahi pae hau o 16.6 ° C (62 ° F) a lilo i aniani kala ʻole ma hope o ka paʻa ʻana. He waika nawaliwali a erosive kona wai, a he mea hoonaukiuki ka mahu i ka maka a me ka ihu.
ʻO ka ʻakika acetic glacial (mea maʻemaʻe), ʻo ia hoʻi, anhydrous acetic acid, mea hoʻohuihui. Paʻa ʻo ia i hau i nā mahana haʻahaʻa a ʻike ʻia ʻo ia ka glacial acetic acid. ʻO ka hoʻonui ʻia ʻana o ka leo i ka wā paʻa i hiki ke naha ka ipu. ʻO ka helu uila he 39 ℃, ʻo ka palena pahū he 4.0% ~ 16.0%, a ʻo ka nui o ka ʻae ʻia i ka lewa ʻaʻole i ʻoi aku ma mua o 25mg/m3. E maloʻo ka ʻakika acetic maʻemaʻe i loko o nā kristal e like me ka hau ma lalo o ka helu heheʻe, no laila ua kapa ʻia ka ʻakika acetic anhydrous.
Hiki ke ʻike ʻia ʻaʻole like nā mea ʻelua, ʻo ka helu uila o ka wai acetic ice he 39 ℃, ʻo ka palena pahū he 4.0% ~ 16.0%, a ʻo ka nui o ka ʻae ʻia i ka lewa ʻaʻole i ʻoi aku ma mua o 25mg/m3, nona ia. i nā waiwai pōʻino, a ʻaʻole ʻo ka ʻakika acetic he waiwai weliweli.
