Sodium Acetate Anhydrous
Lintho tsa Physicochemical:
1. Colourless le pepeneneng monoclinic kristale prismatic kapa tšoeu kristale phofo, odorless kapa hanyenyane asene monko, hanyenyane babang, ho le bonolo ho meteo moeeng o omileng le mongobo.
2. Metsi a qhibilihang (46.5g/100mL, 20℃, PH ea 0.1mol/L aqueous solution ke 8.87), acetone, joalo-joalo, a qhibiliha ka ethanol, empa a sa qhibilihe ka ether.
3.Ntho e qhibilihang (℃): 324
Storge
1. Boloka sebakeng se tiisitsoeng le se omileng.
2. E phuthetsoe ka mokotla oa polasetiki o nang le line, mokotla o lohiloeng kapa mokotla oa sethunya e le seaparo sa ka ntle. Sodium acetate ke deliquescent, kahoo e lokela ho sireletsoa mongobo nakong ea polokelo le lipalangoang. Ho thibetsoe ka thata ho kopana le khase e senyang, ho thibela ho pepesehela letsatsi le pula, le ho e tsamaisa ka sekoahelo sa pula.
Sebelisa
1. Boikemisetso ba loto, zinki, aluminium, tšepe, cobalt, antimony, nickel le tin. Ho rarahana ho tsitsitseng. Thuso, buffer, desiccant, mordant bakeng sa acetylation.
2. E sebelisoa ho khetholla loto, zinki, aluminiamo, tšepe, cobalt, antimony, nickel le tin. E sebelisoa e le moemeli oa esterification ho organic synthesis le likarolo tse ngata joalo ka lithethefatsi tsa lifoto, meriana, ho hatisa le ho daea mordants, li-buffers, li-reagents tsa lik'hemik'hale, li-preservatives tsa nama, li-pigments, ho suha matlalo, joalo-joalo.
3. E sebelisoa e le "buffer", "flavor agent", "flavoring" le pH regulator. Joalo ka sehlare sa setlolo sa tatso, 0.1% -0.3% e ka sebelisoa ho fokotsa monko o mobe le ho thibela ho fetoha ha 'mala ho ntlafatsa tatso. E na le phello e itseng e khahlanong le hlobo, joalo ka ho sebelisa 0.1% -0.3% lihlahisoa tsa surimi le bohobe. E ka boela ea sebelisoa e le moemeli o bolila bakeng sa sauce ea linoko, sauerkraut, mayonnaise, kuku ea tlhapi, boroso, bohobe, kaka e khomarelang, joalo-joalo E kopantsoe le methyl cellulose, phosphate, joalo-joalo, e sebelisetsoang ho ntlafatsa ho boloka lisoseje, bohobe, ho khomarela. likuku, joalo-joalo.
4. E sebelisoa e le scorch inhibitor bakeng sa coking ea rabara ea chloroprene e laoloang ke sebabole. Ka kakaretso, litekanyetso li 0.5 likarolo ka boima. E ka boela ea sebelisoa e le ntho e kopanyang sekhomaretsi sa liphoofolo.
5. Sehlahisoa sena se ka sebelisoa ho eketsa alkaline electroplating tin, empa ha e na phello e totobetseng holim'a mokhoa oa ho roala le oa electroplating, 'me ha se motsoako o hlokahalang. Sodium acetate hangata e sebelisoa joalo ka buffer, joalo ka acid ea zinc plating, alkaline tin plating le electroless nickel plating.
