ʻO ke kuleana o ka waikawa acetic glacial i ka paʻi ʻana a me ke kala ʻana,
Acetic acid, hoʻohana ʻana i ka acetic acid, maʻiʻo acetic acid, mea hana acetic acid,
ʻO ka ʻōlelo kikoʻī (GB/T 1628-2008)

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.

Hoʻohana ʻia nā mea hoʻopuehu i kēlā me kēia lā, akā hiki iā ʻoe ke ʻōlelo koke, no ke aha e hoʻopuehu ai nā mea pena me ka glacial acetic acid e hoʻoponopono ai i ka PH? (Hoʻohui ʻia nā ʻakika organik e hoʻoponopono i ka PH, koe naʻe ka waihoʻoluʻu alkaline disperse)

ʻO ke kumu:

ʻO ke kūpaʻa o nā mea hoʻoheheʻe i loko o ka ʻauʻau wai pili pili i ka waiwai pH. ʻOi aku i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe, inā ʻaʻole i mālama pono ʻia ka pH waiwai o ka ʻauʻau wai, e hana pinepine ia i ka hoʻololi ʻana o ke kukui kala, ʻo nā kumu nui e like me kēia.

(1) E hoʻonui i ka hydrolysis o ka disperse dyes, i ke kaʻina hana o nā dyes, hoʻohui pinepine i ka nui o nā dispersants e like me ka diffusion agent NNO, lignin, sodium carbonate, etc., no laila ua nāwaliwali ka wai, i loko
Ke hoʻoluʻu ʻia ma 130% kiʻekiʻe ka wela, maʻalahi ka hydrolyze, e hopena i ka waihoʻoluʻu māmā a me ke kala ʻeleʻele.
(2) Ma muli o ka emi ʻana o ka decomposition o nā disperse dyes, ka nalowale o ka pūʻulu chromophore, ʻike pinepine ʻia kēia ʻano i nā kala me ka hoʻolālā azo.
(3) ʻO ka hui phenolic i loko o ka molecular structure o ka dye ke kumu i ka hopena ionic ma muli o ka hana o ka alkali, hoʻonui ʻia ka hoʻoheheʻe wai, a hoʻonāwaliwali ʻia ke kala, pinepine ma muli o ka hoʻohui ʻana o ka dispersant i ka ʻauʻau wai. , ka hopena o ka hoʻopuehu ʻana o ka wai me ka alkaline nāwaliwali.
