Incazelo

▶I-Sodium acetate (CH3COONA) usawoti wesodium we-acetic acid.Kubukeka njengosawoti ophuzwayo ongenambala onezinhlobonhlobo zezinhlelo zokusebenza.Embonini, ingasetshenziswa embonini yendwangu ukuze kuncishiswe imifudlana yemfucuza ye-sulfuric acid futhi njenge-photoresist lapho kusetshenziswa odayi be-aniline.Embonini kakhonkolo, ingasetshenziswa njengesivalo sikakhonkolo ukunciphisa umonakalo wamanzi.Ekudleni, ingasetshenziswa njengesinongo.Ingasetshenziswa futhi njengesixazululo sebhafa elebhu.Ngaphezu kwalokho, ibuye isetshenziswe ekushiseni amaphedi, izifudumezi zezandla kanye neqhwa elishisayo.Ukuze isetshenziswe elabhorethri, ingakhiqizwa ukusabela phakathi kwe-acetate ne-sodium carbonate, i-sodium bicarbonate ne-sodium hydroxide.Embonini, ilungiswa kusuka ku-glacial acetic acid ne-sodium hydroxide.

▶Izakhiwo Zamakhemikhali

Usawoti ongenayo i-anhydrous i-crystalline eqinile engenambala;ukuminyana 1.528 g/cm3;iyancibilika ku-324 ° C;inyibilika kakhulu emanzini;incibilika ngokulingene ku-ethanol.I-crystalline trihydrate engenambala inobuningi obungu-1.45 g/cm3;ibola ku-58°C;iyancibilika kakhulu emanzini;i-pH ye-0.1M yesisombululo samanzi ngu-8.9;incibilika ngokulingene ku-ethanol, 5.3 g/100mL.

▶Isitoreji Nezokuthutha

Kufanele igcinwe endaweni eyomile nengenisa umoya, igcinwe kude nokushisa nomswakama ngesikhathi ithuthwa, yehliswe ngokucophelela ukuze igweme umonakalo.Ngaphezu kwalokho, kufanele igcinwe ngokuhlukana nezinto ezinobuthi.

Isicelo

▶Izimboni
I-sodium acetate isetshenziswa embonini yendwangu ukuze kuncishiswe imifudlana yemfucuza ye-sulfuric acid futhi njenge-photoresist ngenkathi kusetshenziswa odayi be-aniline.Iphinde ibe yi-ejenti yokukhetha ekushukeni kwe-chrome futhi isiza ukuvimbela ukuvuthwa kwe-chloroprene ekukhiqizeni irabha yokwenziwa.Ekucubunguleni ukotini wamaphedi kakotini alahlwayo, i-acetate ye-sodium isetshenziselwa ukuqeda ukunqwabelana kukagesi omile.Ibuye isetshenziswe “njengeqhwa elishisayo” esifudumeni sesandla.

▶Ukuphila isikhathi eside
I-sodium acetate isetshenziselwa ukunciphisa ukulimala kwamanzi kukhonkolo ngokusebenza njengesivalo sikakhonkolo, kuyilapho futhi ingeyona ingozi emvelweni futhi ishibhile kunenye indlela evame ukusetshenziswa ye-epoxy yokuvala ukhonkolo ngokumelene nokungena kwamanzi.
▶Isixazululo sebhafa
Njengesisekelo se-conjugate se-acetic acid, isixazululo se-sodium acetate ne-acetic acid singasebenza njengesivimbeli ukuze kugcinwe izinga le-pH elingashintshi.Lokhu kuwusizo ikakhulukazi ekusetshenzisweni kwamakhemikhali e-biochemical lapho ukusabela kuncike ku-pH ebangeni eline-asidi ethambile (pH 4-6).Ibuye isetshenziswe kubathengi OKUSHISA I-PADS noma izifudumezi zezandla futhi ibuye isetshenziswe eqhweni elishisayo.Amakristalu e-sodium acetate trihydrate ancibilika ku-58 °C, ahlakazeka emanzini awo e-crystallization.Lapho zishiselwa cishe ku-100 ° C, futhi ngemva kwalokho zivunyelwe ukupholisa, isixazululo esinamanzi siba supersaturated.Lesi sixazululo siyakwazi ukupholisa kahle kakhulu ekamelweni ngaphandle kokwenza amakristalu.Ngokuchofoza idiski lensimbi kuphedi yokushisisa, kwakheka isikhungo senucleation esibangela ukuthi ikhambi licwebezele libe amakristalu e-trihydrate aqinile futhi.Inqubo yokwenza ibhondi yecrystallization iyingozi kakhulu, yingakho ukushisa kukhishwa.Ukushisa okucashile kwe-fusion cishe ku-264-289 kJ/kg.
