ʻO ke ʻano a me ke ʻano: keʻokeʻo, ke aniani monoclinic a i ʻole ka pauka.
CAS:7757-83-7
Ka helu hehee (℃): 150 (decomposition poho wai)
Māmā pili (wai =1) : 2.63
Huina mole: Na2SO3
Kaumaha Molekala: 126.04(252.04)
Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai (67.8g /100 mL (ʻehiku wai, 18 °C), hiki ʻole ke hoʻoheheʻe i ka ethanol, etc.
ʻO ka sodium Sulfite ka mea maʻalahi a hoʻoheheʻe ʻia i ka sodium sulfate i ka ea. ʻO ka nalowale o ka wai crystalline ma 150 ℃. Ma hope o ka wela, hoʻoheheʻe ʻia i loko o ka hui ʻana o ka sodium sulfide a me ka sodium sulfate. ʻO ka nui o ka mea anhydrous he 2.633. ʻOi aku ka mālie ma mua o ka hydrate a ʻaʻohe loli i ka ea maloʻo. decomposition i loko o nā paʻakai kūpono a hoʻokuʻu i ka sulfur dioxide. ʻO ka sodium sulfite ka ikaika reducibility, a hiki ke hōʻemi i nā ion keleawe i nā iona cuprous (hiki i ka sulfite ke hana i nā paʻakikī me nā iona cuprous a hoʻopaʻa), a hiki ke hoʻemi i nā oxidants nāwaliwali e like me ka phosphotungstic acid. wela a mahele i ka wai, ua maloʻo ka papa ether me ka lime wikiwiki, no kekahi mau hopena me nā koi haʻahaʻa).
Mahele o ka hoohalike pane:
1. Ka hanauna:
SO2+2NaOH===Na2SO3+H2O
H2SO3 + Na2CO3 = = = kākau Na2SO3 + CO2 + H2O
2 nahso3 = = delta = = Na2SO3 + H2O + SO2 kākau
2. Hiki ke emi:
3 na2so3 hno3 + 2 + 2 = = = = 3 na2so4 ʻaʻole kākau + H2O
2Na2SO3+O2====2Na2SO4
3. ʻO ka wela:
4 na2so3 = = delta = = Na2S + 3 na2so4
4. Hoʻohāhā:
Na2SO3 + 3 h2s = = = = 3 kekona i koe + Na2S + 3 h2o [1]
Hoʻomākaukau hale hana
Hoʻomaʻamaʻa ʻia ka hopena sodium carbonate i 40 ℃ a hoʻopiha ʻia me ka sulfur dioxide, a laila hoʻohui ʻia ka nui o ka solution sodium carbonate, a ua crystallized ka hopena ma lalo o ke ʻano o ka pale ʻana i ka pilina me ka ea.

1. Ma hope o ka hoʻoheheʻe ʻana, ka hoʻomaʻamaʻa ʻana a me ka kānana kiʻekiʻe, hoʻohui ʻia ka sulfur i ka sulfur furnace e ka sulfur pump.
2. Ma hope o ka paʻi ʻia ʻana o ka ea, hoʻomaloʻo ʻia a hoʻomaʻemaʻe ʻia, puhi ʻia ka umu ahi sulfur a puhi ʻia ka sulfur e hana i ke kinoea SO2 (funa gas).
3. Hoʻomaʻalili ʻia ke kinoea umu ahi e ka ipu ʻōpala e hoʻihoʻi hou i ka mahu, a laila komo i ka reactor desulfurization. Hoʻopau ʻia ka sulfur sublimation i ke kinoea, a loaʻa ke kinoea maʻemaʻe me 20.5% SO2 maʻiʻo (volume), a laila komo i ka hale kiaʻi absorption.
4, soda me ka hoʻopaʻa 'ia o ka lye, a me ka sulfur dioxide kinoea pane e loaa sodium bisulfite solution.
5, ka sodium sulfite hydrogen sodium solution ma ka hoʻokaʻawale ʻana i ka soda e loaʻa ai ka hopena sodium sulfite.
6, Sodium sulfite solution i loko o ka concentrator, me ka hoʻohana ʻana i ke kaʻina hana hoʻomau mau.
7. E hoʻokomo i ka concentrator mea kūpono i loko o ka centrifuge e ʻike ai i ka hoʻokaʻawale paʻa-wai. ʻO ka paʻa (ka sodium sulfite) e komo i ka mea maloʻo ea, a maloʻo ka huahana i hoʻopau ʻia e ka ea wela.
Hoʻohana hou ʻia ka waiʻona makuahine i ka pahu hāʻawi alkali no ka hana hou ʻana.
1) Hoʻohana ʻia no ka loiloi trace a me ka hoʻoholo ʻana i ka tellurium a me ka niobium a me ka hoʻomākaukau ʻana i ka hopena hoʻomohala, hoʻohana ʻia hoʻi ma ke ʻano he mea hoʻemi;
2) Hoʻohana ʻia e like me ka fiber stabilizer i hana ʻia e ke kanaka, ka mea hoʻomaʻemaʻe lole, ka mea hoʻomohala kiʻi kiʻi, ka dyeing a me ka bleaching deoxidizer, ka ʻono a me ka mea hoʻoemi wai, ka pepa lignin remover, etc.
3) Hoʻohana ʻia e like me kahi reagent analytical maʻamau a me nā mea pale photosensitive;
4) Reductive bleaching agent, nona ka hopena bleaching i ka meaʻai a me ka hopena inhibition ikaika i ka oxidase i ka meaʻai mea kanu.
5) ʻO ka paʻi ʻana a me ke kala ʻana ma ke ʻano he deoxidizer a me ka bleach, hoʻohana ʻia i ka kuke ʻana i nā lole pulupulu like ʻole, hiki ke pale i ka oxidation kūloko o ka pulupulu pulupulu a hoʻopilikia i ka ikaika fiber, a hoʻomaikaʻi i ke keʻokeʻo o ka mea kuke.
6) Hoʻohana ʻia e ka ʻoihana lole ma ke ʻano he stabilizer no nā fiber i hana ʻia e ke kanaka.
7) Hoʻohana ʻia ka ʻoihana uila e hana i nā resistors photosensitive.
8) ʻoihana hoʻomaʻamaʻa wai no ka hoʻomaʻemaʻe ʻana i ka wai, inu wai;
9) Hoʻohana ʻia ma ke ʻano he bleach, preservative, loosening agent a me ka antioxidant i ka ʻoihana meaʻai.
10) Hoʻohana ʻia no ka hana ʻana i ka cellulose sulfite ester, sodium thiosulfate, nā kemika organik, nā lole bleached, a me nā mea ʻē aʻe, i hoʻohana ʻia e like me ka mea hoʻemi, preservative, dechlorination agent, etc.;
11) Hoʻohana ʻia ka hale hana no ka hoʻomākaukau ʻana i ka sulfur dioxide
