Faahfaahinta alaabta
MF: C2H3NaO2
MW: 82.03379
CAS: 127-09-3
1.Sodium acetate waxa kale oo loo yaqaan sodium acetate.Midab la'aan, aan ur lahayn, muraayad monoclinic ah oo hufan, ama budada crystalline cad.
2.In wax soo saarka cuntada, waxaa loo isticmaalaa sida kaydinta xawaash iyo ilaalinta hilibka.Xakamee ifafaale dhegdheg leh oo uu keeno fangaska ee soosaarka roodhida oo u isticmaal ilaalinta hadhuudhka oo leh biyo badan;Alaabtan waxa kale oo loo isticmaali karaa daabacaadda dunta buuga kimikalka dheehaynta (mordant), kaydinta warshadaha sawirida, reagent kiimikaad iyo dhexdhexaadka dawooyinka;Waxa kale oo loo isticmaali karaa sidii alaab cayriin ah oo loogu talagalay soo saarista alaabada kiimikaad ee organic, sida furan acrylic acid, acetate esters, chloroacetic acid, acetic anhydride iyo cinnamic acid.
3. Midab la'aan iyo ur aan lahayn, kaas oo lagu dabooli karo oo lagu guban karo hawada.Ku milmay biyaha iyo eter, wax yar ku milmay ethanol.Barta dhalaalka ah ee sodium acetate trihydrate waa 58 ℃, cufnaanta qaraabada waa buug kiimikaad1.45, barta gubashada kediska ahna waa 607.2 ℃.Ka saar 3 molecules oo biyo ah at 123 ℃.Barta dhalaalka ee sodium acetate anhydrous waa 324 ℃, iyo cufnaanta qaraabada waa 1.528.
Codsiga
1.Anhydrous sodium acetate waxaa loo isticmaali karaa in synthesis organic ee wakiilada esterification, daawooyinka sawiro, daawo, daabacaadda iyo mordants dheeh, buffers, reagents kiimikada, preservatives hilibka, pigments iyo dhinacyo kale oo badan, iyo waxaa loo isticmaali karaa si ay u soo saaraan alaabta kiimikada kala duwan, sida. sida furan propylene chemicalbook enoic acid, acetate iyo chloroacetic acid.Sida kaydka xawaash ahaan, alaabtani waxay ka hortagi kartaa midab-beelka waxayna leedahay saameyn gaar ah oo ka hortagga caarada.Waxa kale oo loo isticmaali karaa sida wakiilka dhanaan ee suugo xawaash ah, kaabajka pickled, majones, keega kalluunka, sausage, rooti, keega bariiska, iwm.
2.Sodium acetate ayaa inta badan door ka ciyaara hagaajinta qiimaha pH ee wasakhda ee daaweynta wasakhda.Sodium acetate waa kiimiko alkaline ah, kaas oo lagu shubi karo biyaha si ay u sameeyaan Oh negative ions, kuwaas oo ka takhalusi kara buuga kiimikada iyo ion acidic ee biyaha, sida h+, nh4+.Qaabka falcelinta hydrolysis-ka ee sodium acetate waa: ch3coo-+h2o= dib loo rogi karo =ch3cooh+oh-.
