I-sodium acetate, leli khemikhali elibonakala lilula, empeleni lidlala izindima ezihlukahlukene ekuphileni kwethu kwansuku zonke. Kusukela ezithasiselweni zokudla kuye ezintweni zokusetshenziswa zamakhemikhali, bese kuba yizisiza zemithi, i-acetate ye-sodium inezinhlobonhlobo zezicelo. Leli phepha lizoxoxa ngezakhiwo ze-sodium acetate, izindlela zokukhiqiza kanye nokusetshenziswa kwayo emikhakheni ehlukene, futhi sibheke phambili ekuthuthukisweni kwayo kwesikhathi esizayo.
1. Izakhiwo eziyisisekelo ze-acetate ye-sodium
I-sodium acetate, ifomula yamakhemikhali i-CH3COONA, iyikristalu esobala engenambala, encibilika emanzini, ine-alkaline. Ikhiqizwa ukusabela kokungathathi hlangothi kwe-acetic acid ne-sodium hydroxide, futhi inomsebenzi wokulawula ibhalansi ye-acid-base. Emoyeni, i-acetate ye-sodium ingakwazi ukumunca amanzi kanye ne-carbon dioxide, ngakho ngokuvamile idinga ukugcinwa ezimweni ezivaliwe.
Okwesibili,i-sodium acetate indlela yokukhiqiza
Ukungathathi hlangothi: Lena indlela evamile yokukhiqiza i-acetate ye-sodium. Ngokuxuba i-acetic acid nesisombululo se-sodium hydroxide, ukusabela kwe-neutralization kwenziwa, bese kuthi amakristalu e-sodium acetate atholwe ngokuhwamuka, i-crystallization kanye nokwehlukana.
I-Catalytic oxidation: Lapho ikhona i-catalyst, i-methanol iphendulana nomoya noma umoya-mpilo ukuze yakhe i-acetic acid, bese isabela ne-sodium hydroxide ukwenza i-sodium acetate.
Indlela yokubuyisela: Ekukhiqizweni kwezimboni, uketshezi oluthile lwemfucuza luqukethe i-acetate ye-sodium, engatholwa ngokuhlanza nokugxilisa ingqondo.
Okwesithathu, inkambu yesicelo se-sodium acetate
Imboni yokudla:I-sodium acetate ngokuvamile isetshenziswa njengesengezo sokudla, njengezilondolozi, izilawuli ze-acidity, njll., Ukwandisa isikhathi seshalofu sokudla, ukuthuthukisa ukunambitheka nokubukeka kokudla.
Imboni yemithi: Emkhakheni wezokwelapha, i-acetate ye-sodium ingasetshenziswa njengento eyisizayo ekulungiseleleni futhi ibambe iqhaza ekukhiqizeni nasekusetshenzisweni kwezidakamizwa.
Imboni yamakhemikhali: I-sodium acetate isetshenziswa embonini yamakhemikhali njengento eluhlaza ukuze kwenziwe amanye amakhemikhali, njenge-vinyl acetate, i-acetate fiber, njll.
Ukuvikelwa kwemvelo: I-sodium acetate ingasetshenziswa futhi ekuhlanzeni indle ukuze kuthuthukiswe umphumela wokwelashwa kwebhayoloji ngokulungisa inani le-pH lendle.
Ezolimo: Kwezolimo, i-sodium acetate ingasetshenziswa njengesithako kumanyolo ukuze kuhlinzekwe imisoco edingekayo ekukhuleni kwezitshalo.
Ukuthuthukiswa kwesikhathi esizayo kwe-acetate ye-sodium
Ngokuthuthukiswa kwesayensi nobuchwepheshe kanye nokuthuthukiswa kokuqwashisa ngokuvikelwa kwemvelo, inqubo yokukhiqiza i-acetate ye-sodium izoba luhlaza kakhulu futhi ibe nemvelo, futhi insimu yesicelo izoqhubeka nokwandisa. Isibonelo, emkhakheni wamandla aqhubekayo,i-sodium acetate kulindeleke ukuthi isetshenziswe njengempahla eluhlaza ekukhiqizeni amandla e-biomass, okuhlinzeka ngendlela entsha yokuguqulwa nokugcinwa kwamandla. Ngaphezu kwalokho, ngokuphishekela impilo enempilo, i-acetate ye-sodium emkhakheni wokudla nemithi izophinde inake kakhulu ukuphepha nokuvikelwa kwemvelo.
V. Isiphetho
Njengekhemikhali enemisebenzi eminingi,i-sodium acetate idlala indima ebalulekile emikhakheni eminingi. Ngokusebenzisa ukuthuthukiswa okuqhubekayo kwezobuchwepheshe kanye nokuthuthukiswa kwenqubo, ukusebenza kahle kokukhiqiza kanye nohlu lokusetshenziswa kwe-acetate ye-sodium kuzothuthukiswa nakakhulu, futhi kube negalelo elikhulu ekuthuthukisweni komphakathi wesintu. Sinesizathu sokukholelwa ukuthi i-sodium acetate izobonisa inani layo eliyingqayizivele emikhakheni eminingi esikhathini esizayo futhi ibe umkhiqizo wamakhemikhali obalulekile.
