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.
I-glacial acetic acid (i-pure matter), okungukuthi, i-anhydrous acetic acid, i-acetic acid ingenye yezinto ezibalulekile ze-organic acid, izinhlanganisela eziphilayo. Iqina ibe yiqhwa ezingeni lokushisa eliphansi, elivame ukwaziwa njenge-glacial acetic acid. Ukunwetshwa kwevolumu ngesikhathi sokuqina kungase kubangele ukuba isiqukathi siphuke. Iphoyinti le-Flash 39℃, umkhawulo wokuqhuma ngu-4.0%~16.0%, ukugxila okuphezulu okuvunyelwe emoyeni akukho ngaphezu kuka-25mg/m3. I-acetic acid ehlanzekile izoba yiqhwa ibe amakristalu eqhwa ngaphansi kwendawo yokuncibilika, ngakho-ke i-acetic acid e-anhydrous ibizwa nangokuthi i-glacial acetic acid.
sebenzisa
Isicelo: Isetshenziselwa ikakhulukazi ukuhlanganiswa kwe-vinyl acetate, i-acetate fiber, i-acetic anhydride, i-acetate, i-acetate yensimbi ne-halogenated acetic acid. Iphinde ibe yimpahla ebalulekile yokwenziwa kwemithi, udayi, isibulala-zinambuzane kanye nokunye ukwakheka kwe-organic. Ngaphezu kwalokho, ibuye isetshenziswe kabanzi ekwenzeni izidakamizwa zezithombe, i-cellulose acetate, izimboni zokunyathelisa nezindwangu zokudaya nezenjoloba, izinyibilikisi zokwenziwa kwamapulasitiki, odayi, izithombe, imithi, izibulala-zinambuzane nezinye izinto zokusetshenziswa ze-organic synthesis.
