1.Sodium acetate tseem hu ua sodium acetate.Tsis muaj xim, tsis muaj ntxhiab, pob tshab monoclinic columnar siv lead ua, lossis dawb crystalline hmoov.
2.Nyob rau hauv cov khoom noj khoom haus, nws yog siv los ua ib qho tsis rau seasoning thiab nqaij preservative.Tswj cov txheej txheem nplaum uas tshwm sim los ntawm cov kab mob hauv cov qhob cij ntau lawm thiab siv rau hauv cov nplej khaws cia nrog cov dej siab;Cov khoom no tseem siv tau los ua cov ntawv luam tawm cov tshuaj pleev luam tawm (mordant), ntas rau kev lag luam yees duab, tshuaj lom neeg thiab kws tshuaj nruab nrab;Nws kuj tseem siv tau los ua cov ntaub ntawv raw rau cov khoom siv tshuaj lom neeg cov khoom siv organic tshuaj, acetate esters, acetic anid, actic anid, actamic acid.
3.Colorless thiab ntxhiab siv lead ua, uas tuaj yeem yog huab cua thiab ua kom muaj cua hauv huab cua.Soluble hauv dej thiab Etaws, me ntsis soluble hauv ethanol.Lub ntsiab lus melting ntawm sodium acetate trihydrate yog 58 ℃, qhov kev sib txheeb siab yog cov tshuaj lom neeg yog 607.2 ℃.Tshem tawm 3 molecules dej ntawm 123 ℃.Lub ntsiab lus melting ntawm anhydrous sodium acetate yog 324 ℃, thiab cov kev sib txheeb ze yog 1.528.
Daim ntawv thov
1.Anhydrus sodium acetate tuaj yeem siv rau hauv cov estification tus neeg sawv cev, nqaij tshuaj ntxuav, nqaij, thiab lwmyam lwm yam, thiab tuaj yeem siv los tsim cov khoom siv ntau yam, xws li Raws li furan propylene tshuaj lom neeg enoic acid, acetate thiab chloroacetic acid.Raws li ib qho ntas rau seasoning, cov khoom no tuaj yeem tiv thaiv kev cog lus thiab muaj qee yam anti mildew effect.Nws kuj tseem tuaj yeem siv ua tus sawv cev qaub rau cov kua zaub, Pickled zaub qhwv, mayonnaise, hnyuv ntxwm, ncuav mog qab zib, ncuav mog qab zib mov, thiab lwm yam.
2.Shodium acetate feem ntau yog lub luag haujlwm hauv kev kho cov pH nqi ntawm cov dej phwj tuaj hauv dej phwj.Sodium acetate yog ib qho tshuaj lom neeg, uas tuaj yeem yog hydrolyzed hauv dej los ua cov tshuaj tsis zoo thiab cov acidic ions hauv dej, xws li h +, nh4 +.Cov tshuaj tiv thaiv hydrolysis ntawm sodium acetate yog: ch3coo- + h2o = reversible = ch3cooh + Oh-.
