[Ulwazi loshicilelo kunye nokudaya] Kutheni kusasaza idayi ukongeza i-acetic acid emkhenkce,
glacial acetic acid kwindima yokudaya, Abavelisi be-acetic ye-glacial, abavelisi be-acetic ye-glacial e-China, Ukusetyenziswa kwe-acetic acid,
Ukucaciswa komgangatho (GB/T 1628-2008)

Iimpawu zePhysicochemical:
1. Ulwelo olungenambala kunye ne-dour ecaphukisayo.
2. Indawo yokunyibilika 16.6 ℃; indawo yokubilisa 117.9℃; Indawo edanyazayo: 39 ℃.
3. Amanzi anyibilikayo, i-ethanol, ibenzene kunye ne-ethyl ether immiscible, enganyibilikiyo kwicarbon disulphide.

Ugcino:
1. Igcinwe kwindawo epholileyo, nengena umoya.
2. Gcina kude nomlilo, shushu. Ixesha elibandayo kufuneka ligcine ubushushu obungaphezulu kwe-16 DEG C, ukuthintela ukuqina. Ngexesha elibandayo, ubushushu kufuneka bugcinwe ngaphezu kwe-16 DEG C ukunqanda/ukuphepha ukuqina.
3. Gcina isitya sivaliwe. Kufuneka yahlulwe kwi-oxidant kunye ne-alkali. Ukuxuba kufuneka kuphetshwe ngazo zonke iindlela.
4. Sebenzisa izibane ezingagqabhukiyo, izixhobo zokungenisa umoya.
5. Izixhobo zoomatshini kunye nezixhobo ezivimbela ukusetyenziswa kwezinto ezilula ukuvelisa iintlantsi.
6. Iindawo zokugcina kufuneka zixhotyiswe ngezixhobo zonyango olungxamisekileyo kunye nezixhobo ezifanelekileyo zezindlu.

Sebenzisa:

1.I-Derivative: Isetyenziswa kakhulu ekwenzeni i-acetic anhydride, i-acetic ether, i-PTA, i-VAC/PVA, i-CA, i-ethanone, i-chloroacetic acid, njl.
2.Pharmaceutical:Acetic acid as solvent and pharmaceuticalraw materials, ikakhulu esetyenziselwa imveliso penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfadiazine, kunye sulfamethoxazole isoxazole, norfloxacin,ciprofloxacin, acetinelic acid, acetyl, preacetyl ,icaffeine, njl.
3.Ephakathi:iacetate,sodium hydrogen di,peracetic acid, njl
4. Idayi kunye noshicilelo olulukiweyo kunye nokudaya: Isetyenziswa kakhulu ukuvelisa iidayi ezisasazwayo kunye nedayi yevat, kunye nokuprintwa kwelaphu kunye nokudaywa
5. I-Synthesis ammonia: Ikwimo ye-cuprammonia acetate, esetyenziswa ekusulungekiseni i-syngas ukususa i-litl CO kunye ne-CO2
6. Ifoto: uMphuhlisi
7. Irabha yendalo: I-Coagulant
8. Ushishino lokwakha: Ukuthintela ikhonkrithi ekukhenkceni9. Kwi-addtin ikwasetyenziswa ngokubanzi kunyango lwamanzi, i-syntheticfiber, i-pesticides, iiplastiki, ufele, ipeyinti, ukusetyenzwa kwesinyithi kunye neshishini lerubha.

Ukusabalalisa idayi zisetyenziswa yonke imihla, kodwa unokuthi ngokukhawuleza, kutheni ukusabalalisa idayi zongeza i-glacial acetic acid ukulungisa i-PH? (I-Organic acids ngoku zongezwa ukulungisa i-PH, ngaphandle kwe-alkaline disperse staining.)

Isizathu kukuba:

Ukuzinza kweedayi ezisasazekileyo kwibhafu yedayi kunxulumene ngokusondeleyo nexabiso le-pH. Ngokukodwa kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu, ukuba ixabiso le-pH lokuhlambela idayi alilawulwa ngokungqongqo, liza kubangela ukuhluka kokukhanya kombala, izizathu eziphambili zilandelayo.

(1) Ibangela i-hydrolysis ekhawulezileyo yeedayi ezisasaza, kwinkqubo yokwenziwa kwedayi, zihlala zongeza inani elikhulu le-diffuser, njenge-diffuser NNO, i-lignin, i-sodium carbonate, ukuze isisombululo sedayi sibuthathaka kwi-alkaline.
Xa idayi nge-130% yobushushu obuphezulu, kulula ukwenza i-hydrolyze, okukhokelela kumbala okhanyayo kunye nokukhanya okufiphele.
(2) Ngenxa yokunciphisa ukubola kweedayi ezisasazwayo, ukulahleka kweqela lesiseko seenwele, le nto idla ngokuhlala kwi-azo structure of dyes.
(3) Iqela le-phenolic kwisakhiwo se-molecular of dyes kubangela ukuphendulwa kwe-ionic ngenxa yesenzo se-alkali, kwaye ukunyibilika kwamanzi kuphuculwe, ngelixa ukudaya okuphezulu kubuthathaka ngokuhambelanayo. Rhoqo, ulwelo olusasazwayo lwedayi lubuthathaka ngealkaline ngenxa yokongezwa kwe-disperant kwindawo yokudaya.
