Sodium Acetate Anhydrous
Nā waiwai physicochemical:
1. ʻAʻohe kala a ʻaʻole hoʻi ka ʻākala monoclinic prismatic crystal a i ʻole ka pauka crystalline keʻokeʻo, ʻala ʻole a ʻala iki paha, ʻawaʻawa iki, maʻalahi ke anā i ka ea maloʻo a pulu.
2. ʻO ka wai hoʻoheheʻe (46.5g / 100mL, 20 ℃, PH o 0.1mol / L aqueous solution he 8.87), acetone, a me nā mea'ē aʻe, hiki ke hoʻoheheʻeʻia i ka ethanol, akā hikiʻole ke hoʻopili i ka ether.
3. Kekahi hehee (℃): 324
Storge
1. E mālama i kahi i sila a maloʻo.
2. Hoʻopili ʻia me ka ʻeke ʻeke i hoʻopaʻa ʻia, ʻeke i ulana ʻia a i ʻole ʻeke pū e like me ke kapa waho. He deliquescent ka sodium acetate, no laila pono e pale ʻia mai ka makū i ka wā o ka mālama ʻana a me ka lawe ʻana. ʻAʻole loa e hoʻopili ʻia me ke kinoea corrosive, pale i ka ʻike ʻana i ka lā a me ka ua, a lawe pū me ka uhi ua.
Hoʻohana
1. Ka hoʻoholo ʻana o ke kēpau, zinc, aluminika, hao, cobalt, antimony, nickel a me ka tin. Mea hoʻopaʻa paʻakikī. He mea kōkua, hoʻopaʻa, desiccant, mordant no ka acetylation.
2. Hoʻohana ʻia no ka hoʻoholo ʻana i ke kēpau, zinc, aluminika, hao, cobalt, antimony, nickel, a me ka tin. Hoʻohana ʻia ma ke ʻano he esterification agent i ka organik synthesis a me nā ʻano he nui e like me nā lāʻau lapaʻau kiʻi, nā lāʻau lapaʻau, ka paʻi ʻana a me ka hoʻoheheʻe ʻana i nā mordants, buffers, chemical reagents, meat preservatives, pigments, tanning, etc.
3. Hoʻohanaʻia ma keʻano he pale, meaʻono, meaʻono a me ka pH regulator. Ma ke ʻano he pale o ka mea ʻono, hiki ke hoʻohana ʻia ka 0.1% -0.3% e hoʻopau i ka ʻala ʻino a pale i ka discoloration e hoʻomaikaʻi i ka ʻono. Loaʻa iā ia kahi hopena anti-mold, e like me ka hoʻohana ʻana i ka 0.1% -0.3% i nā huahana surimi a me ka berena. Hiki ke hoʻohana ʻia e like me ka mea ʻawaʻawa no ka hoʻomoʻa ʻana i ka ʻuala, sauerkraut, mayonnaise, iʻa keke, sausage, berena, sticky keke, etc. Hoʻohui ʻia me ka methyl cellulose, phosphate, etc. keke, etc.
4. Hoʻohana ʻia ma ke ʻano he mea pale no ka sulfur-regulated chloroprene rubber coking. ʻO ka maʻamau he 0.5 mau ʻāpana ma ka nui. Hiki ke hoʻohana ʻia ma ke ʻano he crosslinking agent no ke kāpili holoholona.
5. Hiki ke hoʻohana ʻia kēia huahana e hoʻohui i ka tin electroplating alkaline, akā ʻaʻohe hopena i ʻike ʻia i ke kaʻina hana a me ka electroplating, a ʻaʻole ia he mea pono. Hoʻohana pinepine ʻia ʻo Sodium acetate ma ke ʻano he pale, e like me ka plating zinc acid, alkaline tin plating a me ka electroless nickel plating.
