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.
Okokuqala, imvelo ihlukile
1, i-ice acetic acid: iyi-acetic acid anhydrous, i-acetic acid ingenye yama-acids abalulekile e-organic, izinhlanganisela eziphilayo.
2, i-acetic acid: i-organic monic acid, ingxenye eyinhloko kaviniga.
Okwesibili, izici ezahlukene
1, i-glacial acetic acid: iqina ibe yiqhwa ezingeni lokushisa eliphansi, elivame ukwaziwa njenge-glacial acetic acid. Ukunwetshwa kwevolumu ngesikhathi sokuqina kungase kubangele ukuthi isiqukathi siqhume. Iphoyinti le-flash lingu-39℃, umkhawulo wokuqhuma ngu-4.0% ~ 16.0%, futhi ukugxila okuphezulu okuvunyelwe emoyeni akudluli ku-25mg/m3. I-acetic acid ehlanzekile izoba yiqhwa ibe amakristalu afana neqhwa ngaphansi kwendawo encibilikayo, ngakho-ke i-acetic acid enganamanzi ibizwa nangokuthi i-glacial acetic acid.
2, i-acetic acid: iqukethe ama-98% e-glacial acetic acid, ukuminyana okuhlobene (amanzi angu-1): 1.050; I-Viscosity (mPa.s) : 1.22 (20℃); Umfutho we-vapor ku-20℃ (KPa) : 1.5; Ukubukeka nephunga: Uketshezi olungenambala olunephunga le-acetic acid.
Okuthathu, ukusetshenziswa okuhlukile
1, i-glacial acetic acid: ikakhulukazi esetshenziselwa 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.
2, i-acetic acid: ingasetshenziswa njengesilawuli se-acidity, i-acidifier, i-ejenti yokukhetha, i-flavoring ejenti, izinongo, njll.
