1.Sodium acetate inonziwo sodium acetate.Isina ruvara, isina kunhuhwirira, yakajeka monoclinic columnar crystal, kana chena crystalline poda.
2.Mukugadzirwa kwechikafu, inoshandiswa sechivharo chekurunga uye chekuchengetedza nyama.Dzora chiitiko chinonamira chinokonzerwa nefungi mukugadzirwa kwechingwa uye chishandise mukuchengetedza zviyo zvine mvura yakawanda;Ichi chigadzirwa chinogona zvakare kushandiswa semachira ekudhinda kemikari bhuku rinodhaya rinobatsira (mordant), buffer yeindasitiri yemifananidzo, kemikari reagent uye yepakati pemishonga;Inogona zvakare kushandiswa seyakagadzirwa zvinhu zvekugadzira organic makemikari zvigadzirwa, senge furan acrylic acid, acetate esters, chloroacetic acid, acetic anhydride uye cinnamic acid.
3.Isina ruvara uye isina kunhuhwirira crystal, iyo inogona kuvharwa uye inopisa mumhepo.Soluble mumvura uye ether, zvishoma soluble mu ethanol.Iyo yakanyunguduka yesodium acetate trihydrate i58 ℃, hukama hwehukama ichemicalbook1.45, uye nzvimbo yekutsva yega i607.2 ℃.Bvisa mamorekuru matatu emvura pa123 ℃.Iyo yakanyungudika yeanhydrous sodium acetate i324 ℃, uye hukama hwehukama i1.528.
Application
1.Anhydrous sodium acetate inogona kushandiswa mu organic synthesis ye esterification agents, mapikicha emishonga, mishonga, kudhinda uye kudhaya modants, buffers, reagents remakemikari, kuchengetedza nyama, pigments nezvimwe zvinhu zvakawanda, uye zvinogona kushandiswa kugadzira zvakasiyana-siyana zvemakemikari zvigadzirwa, zvakadai. sefuran propylene chemicalbook enoic acid, acetate uye chloroacetic acid.Sevhavha yekurunga, chigadzirwa ichi chinogona kudzivirira kushanduka uye chine imwe anti mildew athari.Inogona zvakare kushandiswa seyakavava mumiriri yekurunga sosi, yakabikwa kabichi, mayonnaise, keke rehove, soseji, chingwa, keke remupunga, nezvimwe.
2.Sodium acetate inonyanya kuita basa rekugadzirisa pH kukosha kwetsvina mukugadzirisa tsvina.Sodium acetate ikemikari yealkaline, inogona kuiswa hydrolyzed mumvura kuti iite Oh negative ions, iyo inogona kuderedza chemicalbook uye acidic ions mumvura, yakadai seh +, nh4 +.Iyo hydrolysis reaction formula ye sodium acetate ndeiyi: ch3coo-+h2o= reversible =ch3cooh+oh-.
