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.
Ngokubaluleka okwandayo kwemithombo yamanzi, ukuthuthwa kwendle nakho sekuqalile ukubonakala emehlweni omphakathi, futhi i-sodium acetate iyisici esibaluleke kakhulu.
Okokuqala, i-acetate ye-sodium iyi-ejenti enhle yokubhafa. Esixazululo, ingakwazi ukuguqula nge-acetic acid nama-acetate ions ukuze kugcinwe ukuzinza kwevelu ye-pH yesisombululo. Lokhu kwenza i-sodium acetate isetshenziswe kabanzi embonini yokudla, njengesakhiwo semvubelo yesinkwa, esingalawula indawo yokukhula yemvubelo yesinkwa futhi igcine umsebenzi wayo osezingeni eliphezulu.
Okwesibili, i-acetate ye-sodium inomphumela wokulondoloza. Ingakwazi ukufeza imiphumela ephikisana nokugqwala nge-ionizing acetate ions ukuvimbela ukukhula kwamagciwane. Embonini yezimonyo, i-acetate ye-sodium ingasetshenziswa njengesilondolozi ukuze kuvikelwe izimonyo ekungcoleni kwamagciwane nokwandisa impilo yazo yeshalofu.
Ngaphezu kwalokho, i-acetate ye-sodium nayo ingasetshenziswa njenge-detergent. Inomsebenzi wokuthambisa ikhwalithi yamanzi futhi ingahlangana ne-calcium ne-magnesium ions ukwakha i-calcium ne-magnesium acetate enganciki kalula, ngaleyo ndlela yehlise ubulukhuni bekhwalithi yamanzi. Lokhu kwenza i-sodium acetate isetshenziswe kabanzi embonini yokuhlanza.
Ekugcineni, i-acetate ye-sodium ingasetshenziswa futhi njengento eluhlaza yezidakamizwa. Ingasetshenziselwa ukuhlanganisa ezinye izidakamizwa, njenge-sodium ne-potassium acetate, ekwelapheni izifo ezifana ne-arrhythmia.
I-sodium acetate isetshenziswa emikhakheni ehlukahlukene njengokudla, izimonyo, okokuhlanza, kanye nemithi. Uma kudingeka, sicela ukhululeke ukuxhumana nokuxhumana.
