imikhiqizo
Umhlinzeki Wefekthri Ikhwalithi ephezulu ye-Sodium Acetate Supplier CAS 127-09-3
Imininingwane yomkhiqizo
MF: C2H3NaO2
MW: 82.03379
CAS: 127-09-3
I-1.Sodium acetate yaziwa nangokuthi i-sodium acetate.Ikristalu elingenambala, elingenaphunga, elisobala le-monoclinic columnar, noma i-white crystalline powder.
2.Ekukhiqizweni kokudla, kusetshenziswa njengesivimbeli sezinongo kanye nesilondolozi senyama.Lawula into enamathelayo ebangelwa isikhunta ekukhiqizweni kwesinkwa futhi usisebenzise ekulondolozeni okusanhlamvu okunokuqukethwe kwamanzi amaningi;Lo mkhiqizo ungasetshenziswa futhi njenge-textile printing chemicalbook dyeing auxiliary (Mordant), i-buffer yemboni yezithombe, i-reagent yamakhemikhali kanye ne-intermediate pharmaceutical;Ingasetshenziswa futhi njengezinto zokusetshenziswa zokwenziwa kwemikhiqizo yamakhemikhali ephilayo, njenge-furan acrylic acid, i-acetate esters, i-chloroacetic acid, i-acetic anhydride ne-cinnamic acid.
3.Ikristalu engenambala futhi engenaphunga, engakwazi ukumelana nesimo sezulu futhi isha emoyeni.Incibilika emanzini ne-ether, inyibilika kancane ku-ethanol.Iphuzu elincibilikayo le-sodium acetate trihydrate ngu-58 ℃, ukuminyana okuhlobene yi-chemicalbook1.45, kanti indawo evuthayo ezenzakalelayo ingu-607.2 ℃.Susa ama-molecule angu-3 wamanzi ku-123 ℃.Indawo encibilikayo ye-anhydrous sodium acetate ingu-324 ℃, kanti ukuminyana okuhlobene ngu-1.528.
Isicelo
I-1.Anhydrous sodium acetate ingasetshenziswa ku-organic synthesis ye-esterification agents, izidakamizwa zezithombe, imithi, ukuphrinta nokudaya ama-modants, ama-buffers, ama-reagents amakhemikhali, izilondolozi zenyama, izingulube nezinye izici eziningi, futhi ingasetshenziswa ukukhiqiza imikhiqizo ehlukahlukene yamakhemikhali, njenge-furan propylene chemicalbook enoic acid, acetate ne-chloroacetic acid.Njengesigcinalwazi sezinongo, lo mkhiqizo ungavimbela ukuguquguquka futhi unomphumela othile wokunqanda isikhutha.Ingasetshenziswa futhi njenge-ejenti emuncu ye-sauce yesinongo, iklabishi elifakwe emanzini anosawoti, imayonnaise, ikhekhe lenhlanzi, isoseji, isinkwa, ikhekhe lelayisi, njll.
I-2.I-acetate ye-sodium ngokuyinhloko idlala indima ekulungiseni inani le-pH lendle ekuhlanzeni indle.I-sodium acetate ikhemikhali ye-alkaline, engenziwa i-hydrolyzed emanzini ukuze yakhe ama-ion a-Oh negative, angakwazi ukwenza i-chemicalbook nama-ion ane-asidi angasebenzi emanzini, afana no-h+, nh4+.Ifomula yokusabela kwe-hydrolysis ye-sodium acetate ithi: ch3coo-+h2o= ehlehliswayo =ch3cooh+oh-.
