1.ʻO ka sodium acetate ka mea iʻikeʻia he sodium acetate.ʻAʻole waihoʻoluʻu, ʻala ʻole, aniani monoclinic columnar crystal, a i ʻole ka pauka crystalline keʻokeʻo.
2. I ka hana ʻana i ka meaʻai, hoʻohana ʻia ia ma ke ʻano he pale no ka hoʻoulu ʻana a me ka mālama ʻana i ka ʻiʻo.E hoʻopaʻa i ke ʻano ʻokoʻa i hana ʻia e nā fungi i ka hana ʻana i ka berena a hoʻohana iā ia i ka mālama ʻana i ka palaoa me ka nui o ka wai;Hiki ke hoʻohana ʻia kēia huahana ma ke ʻano he mea paʻi kiʻi kiʻi puke dyeing auxiliary (mordant), pale no ka ʻoihana kiʻi kiʻi, reagent kemika a me ka lāʻau waena;Hiki ke hoʻohana ʻia e like me nā mea maka no ka synthesis o nā huahana kemika organik, e like me furan acrylic acid, acetate esters, chloroacetic acid, acetic anhydride a me cinnamic acid.
3.Colorless a me odorless kristal, hiki ke weathered a combustible i ka lewa.Hiki ke hoʻoheheʻe ʻia i ka wai a me ka etera, hiki ke hoʻoheheʻe ʻia i ka ethanol.ʻO ka helu hoʻoheheʻe o ka sodium acetate trihydrate he 58 ℃, ʻo ke kiʻekiʻe pili ʻo chemicalbook1.45, a ʻo ka helu hoʻopau ʻana he 607.2 ℃.Wehe i 3 mau mole wai ma 123 ℃.ʻO ka helu hoʻoheheʻe o ka sodium acetate anhydrous he 324 ℃, a ʻo ka pānaʻi pili he 1.528.

1.Anhydrous sodium acetate hiki ke hoʻohana i ka organic synthesis o esterification agents, kiʻi lāʻau lāʻau lapaʻau, paʻi a dyeing mordants, buffers, chemical reagents, meat preservatives, pigments a me nā mea he nui, a hiki ke hoʻohana ʻia e hana i nā huahana kemika like ʻole. e like me furan propylene chemicalbook enoic acid, acetate a me chloroacetic acid.Ma ke ʻano he pale no ka hoʻoulu ʻana, hiki i kēia huahana ke pale i ka discoloration a loaʻa kekahi hopena anti mildew.Hiki ke hoʻohana ʻia ma ke ʻano he mea ʻawaʻawa no ka hoʻomoʻa ʻana i ka ʻuala, kāpīpī pickled, mayonnaise, keke iʻa, sausage, berena, keke raiki, etc.
ʻO 2.Sodium acetate ka mea nui i ka hoʻoponopono ʻana i ka waiwai pH o ka wai i loko o ka mālama ʻana i ka wai.ʻO ka Sodium acetate kahi kinikini alkaline, hiki ke hoʻoheheʻe ʻia i loko o ka wai e hana i nā ion ʻino Oh, hiki ke hoʻokaʻawale i ka puke kemika a me nā ion acidic i loko o ka wai, e like me h+, nh4+.ʻO ke kumu hoʻohālikelike hydrolysis o ka sodium acetate: ch3coo-+h2o= hoʻohuli ʻia =ch3cooh+oh-.
