Kungani odayi abahlakazayo bengeza i-glacial acetic acid,
i-glacial acetic acid yasekhaya, I-Glacial Acetic Acid, Abakhiqizi be-glacial acetic acid, Abahlinzeki be-Glacial Acetic Acid, I-Hebei glacial acetic acid,
Ukucaciswa kwekhwalithi(GB/T 1628-2008)

Izici ze-Physicochemical:
1. Uketshezi olungenambala kanye ne-dour ecasulayo.
2. Iphuzu elincibilikayo 16.6 ℃; indawo yokubilisa 117.9 ℃; Iphoyinti elikhanyayo : 39 ℃.
3. Amanzi ancibilikayo, i-ethanol, i-benzene ne-ethyl ether immiscible, engancibiliki ku-carbon disulphide.

Isitoreji:
1. Igcinwe endaweni epholile, nengena umoya.
2. Gcina kude nomlilo, shisa. Isikhathi esibandayo kufanele sigcine izinga lokushisa elingaphezu kuka-16 ° C, ukuvimbela ukuqina. Ngesikhathi esibandayo, izinga lokushisa kufanele ligcinwe lingaphezu kuka-16 DEG C ukuvimbela/ukugwema ukuqina.
3. Gcina isitsha sivaliwe. Kufanele ihlukaniswe ne-oxidant ne-alkali. Ukuxuba kufanele kugwenywe ngazo zonke izindlela.
4. Sebenzisa izibani ezingaqhumi, izindawo zokungena komoya.
5. Imishini kanye namathuluzi avimbela ukusetshenziswa kwezinhlansi okulula ukukhiqiza.
6. Izindawo zokugcina kufanele zifakwe izinto zokwelashwa eziphuthumayo kanye nempahla yezindlu ezifanele.

Sebenzisa:

I-1.Okuphuma kuyo:Isetshenziswa kakhulu ekuhlanganiseni i-acetic anhydride,i-acetic ether,i-PTA, i-VAC/PVA, i-CA, i-ethonone, i-chloroacetic acid, njll.
2.Ezemithi:I-acetic acid njengezinto ezincibilikisayo nezinto zokusetshenziswa kwemithi, ikakhulukazi esetshenziselwa ukukhiqizwa kwe-penicilin G potas-sium, i-penicilin G sodium, i-penicillin procaine, i-acetanilide, i-sulfadiazine, ne-sulfamethoxazole isoxazole, i-norfloxacin, i-ciprofloxacin, i-acetinalic acid, i-acetinalic acid, i-acetinalic acid , i-caffeine, njll.
3.Okumaphakathi:i-acetate,i-sodium hydrogen di,i-peracetic acid, njll
4. Ukuphrinta kwendwangu kanye nokudaya kwendwangu: Isetshenziswa kakhulu ukukhiqiza odayi abahlakazayo namadayi we-vat, nokuphrinta kwezindwangu kanye nokucubungula ukudaya
5. I-synthesis ammonia: Ngendlela ye-cuprammonia acetate, esetshenziswa ekucwengisiseni ama-syngas ukususa i-litl CO ne-CO2
6. Isithombe: Unjiniyela
7. Irabha yemvelo: I-Coagulant
8. Imboni yezokwakha: Ukuvimbela ukhonkolo ekushiseni9. I-Addtin ibuye isetshenziswe kabanzi ekwelapheni amanzi, i-syntheticfiber, izibulala-zinambuzane, amapulasitiki, isikhumba, upende, ukucubungula insimbi kanye nemboni yenjoloba.

Odayi abahlakazayo basetshenziswa nsuku zonke, kodwa ungasho ngokushesha, kungani odayi abahlakazayo bengeza i-glacial acetic acid ukulungisa i-PH? (Ama-Organic acids manje ayangezwa ukuze kulungiswe i-PH, ngaphandle kwamabala e-alkaline disperse.)

Isizathu siwukuthi:

Ukuzinza kodayi abahlakazayo ekugezeni kukadayi kuhlobene eduze nenani le-pH. Ikakhulukazi ekushiseni okuphezulu nokucindezela okuphezulu, uma inani le-pH lokugeza udayi lingalawulwa ngokuqinile, lizovame ukubangela ukuhlukahluka kokukhanya kombala, izizathu eziyinhloko zilandelayo.

(1) Imbangela ukusheshisa kwe-hydrolysis yodayi abahlakazayo, lapho kwenziwa udayi, kuvame ukwengeza inani elikhulu le-diffuser, njenge-diffuser NNO, i-lignin, i-sodium carbonate, ukuze ikhambi likadayi libe yi-alkaline ebuthakathaka.
Uma udaya ngezinga lokushisa eliphakeme elingu-130%, kulula ukwenza i-hydrolyze, okuholela kumbala okhanyayo nokukhanya okufiphele.
(2) Ngenxa yokuncishiswa kokubola kwamadayi ahlakazayo, ukulahlekelwa kweqembu lesisekelo sezinwele, lesi simo sivame ukuba sesakhiwo se-azo samadayi.
(3) Iqembu le-phenolic esakhiweni samangqamuzana odayi libangela ukusabela kwe-ionic ngenxa yesenzo se-alkali, futhi ukuncibilika kwamanzi kuyathuthukiswa, kuyilapho ukudaya okuphezulu kuba buthaka ngokuhambisanayo. Ngokuvamile, uketshezi oluhlakazayo lwamadayi luyi-alkali ebuthakathaka ngenxa yokwengezwa kwe-disperant kubhavu wokudaya.
