Inkcazo

▶Isodium acetate (CH3COONA) yityuwa yesodium yeacetic acid.Kubonakala njengetyuwa engenambala i-deliquescent enoluhlu olubanzi lwezicelo.Kumzi-mveliso, inokusetyenziswa kushishino lwamalaphu ukuze kunqandwe imilambo yenkunkuma ye-sulfuric kunye ne-photoresist xa usebenzisa iidayi ze-aniline.Kushishino lwekhonkrithi, lunokusetyenziswa njengesitywini sekhonkrithi ukuthomalalisa umonakalo wamanzi.Ekutyeni, ingasetyenziswa njengesinongo.Isenokusetyenziswa njengesisombululo sesithinteli kwilebhu.Ukongeza, isetyenziselwa ukufudumeza iipads, izifudumezi zezandla kunye nomkhenkce oshushu.Ukusetyenziswa kwelabhoratri, inokuveliswa ngokusabela phakathi kwe-acetate kunye ne-sodium carbonate, i-sodium bicarbonate kunye ne-sodium hydroxide.Kwishishini, ilungiselelwe kwi-glacial acetic acid kunye ne-sodium hydroxide.

▶ Iimpawu zeMichiza

Ityuwa yeAnhydrous yikristale engenambala eqinileyo;ubuninzi 1.528 g/cm3;iyanyibilika kwi-324 ° C;Inyibilika kakhulu emanzini;Inyibilika ngokuphakathi kwi-ethanol.I-crystalline trihydrate engenambala inobuninzi be-1.45 g / cm3;ibola kwi-58 ° C;iyanyibilika kakhulu emanzini;i-pH ye-0.1M isisombululo samanzi ngu-8.9;ngokuphakathi ukunyibilika kwi-ethanol, 5.3 g/100mL.

▶Ukugcinwa kunye noThutho

Kufuneka igcinwe kwindawo eyomileyo kunye neyokungenisa umoya, igcinwe kude nobushushu kunye nokufuma ngexesha lokuthutha, ikhutshwe ngononophelo ukwenzela ukuphepha umonakalo.Ngaphezu koko, kufuneka igcinwe ngokwahlukileyo kwizinto eziyityhefu.

Isicelo

▶Amashishini
I-acetate yesodium isetyenziswa kushishino lwamalaphu ukunqanda imijelo yenkunkuma ye-sulfuric acid kunye ne-photoresist ngelixa usebenzisa iidayi ze-aniline.Ikwayi-agent yokuchola kwi-chrome tanning kwaye inceda ukuthintela uvulcanization ye-chloroprene kwimveliso yerabha yokwenziwa.Ekucubunguleni ikotoni yeepotton pads ezilahlwayo, i-acetate yesodium isetyenziselwa ukuphelisa ukwakhiwa kombane omileyo.Ikwasetyenziswa “njengomkhenkce oshushu” kwisifudumezi sesandla.

▶Ukuphila ixesha elide
I-sodium acetate isetyenziselwa ukuthomalalisa ukonakaliswa kwamanzi kwikhonkrithi ngokusebenza njengesitywini sekhonkrithi, ngeli lixa ikhuselekile kokusingqongileyo kwaye inexabiso eliphantsi kuneyona ndlela iqhelekileyo esetyenziswa epoxy yokutywina ikhonkrithi ngokuchasene nokungena kwamanzi.
▶Isisombululo sesithinteli
Njengesiseko se-conjugate ye-acetic acid, isisombululo se-acetate ye-sodium kunye ne-acetic acid inokusebenza njenge-buffer ukugcina i-pH yezinga elingaguqukiyo.Oku kuluncedo ngokukodwa kwizicelo ze-biochemical apho iimpendulo zixhomekeke kwi-pH kuluhlu oluncinci lwe-asidi (pH 4-6).Ikwasetyenziswa kwi-HEATING PADS yabathengi okanye izifudumezi zezandla kwaye iphinda isetyenziswe kwi-ice.Sodium acetate trihydrate crystals inyibilika kwi-58 ° C, inyibilika emanzini abo e-crystallization.Xa zifudunyezwa malunga ne-100 ° C, kwaye emva koko zivunyelwe ukuba ziphole, isisombululo esimanzi siba yi-supersaturated.Esi sisombululo sinakho ukupholisa okuphezulu kwiqondo lokushisa ngaphandle kokwenza iikristale.Ngokucofa kwidiski yesinyithi kwindawo yokufudumeza, iziko le-nucleation lenziwa elibangela ukuba isisombululo sibe yikristale kwiikristale eziqinileyo ze-trihydrate kwakhona.Inkqubo yokwenza i-bond ye-crystallization i-exothermic, ngoko ke ubushushu buphuma.Ubushushu obufihliweyo bokudibanisa malunga ne-264-289 kJ / kg.
