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 udayi uhlakaza nge-glacial acetic acid ukuze ulungise i-PH? (Ama-Organic acids manje ayangezwa ukuze kulungiswe i-PH, ngaphandle kokudaya kwe-alkaline disperse)
Isizathu siwukuthi:
Ukuzinza kodayi abahlakazayo ekugezeni kokudaya 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 ukushesha kwe-hydrolysis yodayi abahlakazayo, ekukhiqizeni odayi, kuvame ukwengeza inani elikhulu lama-dispersants njenge-ejenti yokusabalalisa i-NNO, i-lignin, i-sodium carbonate, njll., ukuze udayi ube ne-alkaline ebuthakathaka,
Uma udaya ngezinga lokushisa eliphakeme elingu-130%, kulula ukwenza i-hydrolyze, okuholela kumbala okhanyayo nombala obuthakathaka.
(2) Ngenxa yokuncishiswa kokubola kodayi abahlakazayo, ukulahlekelwa kweqembu le-chromophore, lesi simo sivame ukuba odayi abanesakhiwo se-azo.
(3) Iqembu le-phenolic esakhiweni samangqamuzana odayi libangela ukusabela kwe-ionic ngenxa yesenzo se-alkali, ukuncibilika kwamanzi kuyathuthukiswa, futhi ukudaya kuba buthakathaka ngokufanele, ngokuvamile ngenxa yokwengezwa kwe-disperant kubhavu lokudaya. , okuholela ekuhlakazweni kwedayi nge-alkaline ebuthakathaka.
