Ukusetshenziswa kwe-acetic acid kubanzi kakhulu, ingabe wazi konke?
Ukusetshenziswa kwei-acetic acidibanzi kangaka, wazi konke?,
I-acetic acid yaseShayina, I-ice -acetic acid abakhiqizi baseShayina, i-acetic acid, abakhiqizi be-acetic acid, Inani le-acetic acid,

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-acetinelic acid, i-acetinalic acid, i-prefloxacin, i-acetynelic , 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.
Eminyakeni yamuva nje, i-methamphetamine ibilokhu igqama.Abakhiqizi nabakhiqizi ezimbonini nasezinkundleni eziningi sebeqalile ukuthenga inqwaba ye-methamphetamine, okwenze imakethe ye-methamphetamine yathuthuka futhi yanda ngokushesha.
Njenge-fatty acid ekhona emvelweni, i-lyceine ayinayo kuphela isidingo esikhulu semakethe, kodwa futhi inhlanganisela yemvelo enephunga elimuncu nelicasulayo.
Kunabantu abaningi kakhulu abadinga i-methamphetamine ngoba kuningi futhi kuningi ukusetshenziswa kwe-methamphetamine, futhi iyinketho engcono kakhulu ekukhiqizeni, ekukhiqizeni nasekucubunguleni izinkambu eziningi.
Ngakho-ke umbuzo uvela, yiziphi ukusetshenziswa kwe-methamphetamine?
1. Ekuphileni kwansuku zonke komndeni, sebenzisa njenge-ejenti yokususa ukungcola;
2. Isetshenziswa njenge-pH yokucubungula nokukhiqiza ukudla;
3. Ezimbonini zezimboni zezibulala-zinambuzane, imithi kanye nodayi, zisebenzise njengezincibilikisi nezinto zokusetshenziswa.
Ngaphezu kwezinjongo ezingenhla,i-acetic acidfuthi idlala indima enkulu emikhakheni yezimboni efana ne-synthetic fiber kanye nokudaya nokuluka.
Nokho, indlela ejabulisa kakhulu ukubala ukusetshenziswa kwe-ice cinemic acid ekukhiqizeni uviniga kanye nesikhunta esidliwayo:
1. Ukukhiqizwa kukaviniga:
Ukusetshenziswa okunengqondo kwe-ice acetic acid ekukhiqizeni uviniga akukwazi nje ukusiza abakhiqizi ukunciphisa izindleko zokukhiqiza uviniga, kodwa futhi kuzinzisa ikhwalithi yeviniga, ukwenza ukulawulwa komkhiqizo kube lula, kulula, futhi kuthuthukise ukuncintisana kwemakethe yeviniga;
