Sodium Acetate Anhydrous
Amioga fa'aletino:
.
2. Solubility vai (46.5g / 100mL, 20 ℃, PH o 0.1mol / L vaifofo vai o le 8.87), acetone, ma isi, soluble i ethanol, ae le mafai ona solu i eter.
3. Liu liusuavai (℃): 324
Storge
1. Teu i se nofoaga fa'amau ma mago.
2. Fa'aputu i taga palasitika laina, ato lalaga po'o taga fana e fai ma peleue pito i fafo. O le sodium acetate e manaia, o lea e tatau ai ona puipuia mai le susu i le taimi o le teuina ma le felauaiga. E matua faʻasaina le faʻafesoʻotaʻi ma le kasa pala, puipuia le faʻaalia i le la ma le timu, ma felauaiga i le ufi timu.
Fa'aoga
1. Fuafuaga o le taʻitaʻi, zinc, alumini, uʻamea, cobalt, antimony, nickel ma apa. Fa'amautu fa'alavelave. Auxiliary, buffer, desiccant, mordant mo acetylation.
2. Fa'aaoga e fuafua ai le ta'ita'i, zinc, alumini, u'amea, cobalt, antimony, nickel, ma apa. Faʻaaogaina e avea o se esterification agent i organic synthesis ma le tele o itu e pei o ata vailaʻau, vailaʻau, lolomi ma vali mordants, paʻu, vailaʻau vailaʻau, faʻasao aano o manu, pigments, tanning, ma isi.
3. Faʻaaogaina e fai ma faʻamaufaʻailoga, faʻamaʻi meaʻai, faʻamaʻi meaʻai ma le pH regulator. I le avea ai ma se paʻu o mea e faʻamalieina ai meaʻai, 0.1% -0.3% e mafai ona faʻaaogaina e faʻaitiitia ai le manogi leaga ma puipuia ai le faʻaleagaina e faʻaleleia ai le tofo. O lo'o i ai se a'afiaga fa'apitoa, e pei o le fa'aaogaina o le 0.1% -0.3% i oloa surimi ma falaoa. E mafai foʻi ona faʻaaogaina e fai ma sui oona mo le faʻafefeteina o sosi, sauerkraut, mayonnaise, keke iʻa, sosisi, falaoa, keke pipii, ma isi. Faʻafefiloi ma methyl cellulose, phosphate, ma isi, faʻaaogaina e faʻaleleia ai le faʻasaoina o sosisi, falaoa, pipii. keke, ma isi.
4. Fa'aaogaina e fai ma fa'a'ainitaneti mo le sulfur-regulated chloroprene rubber coking. Ole fua ole masani ole 0.5 vaega ile mamafa. E mafai foi ona faʻaaogaina e fai ma sui faʻafesoʻotaʻi mo kelu manu.
5. O lenei oloa e mafai ona faʻaaogaina e faʻaopopo ai le alkaline electroplating apa, ae e leai se aafiaga manino i luga o le faʻapipiʻiina ma le eletise eletise, ma e le o se mea e manaʻomia. O le sodium acetate e masani ona faʻaaogaina e fai ma paʻu, e pei o le faʻapipiʻiina o le zinc, faʻapipiʻi apa alkaline ma le faʻapipiʻi nickel electroless.
