ʻAkika Phosphorous，he mea hoʻohuihui ʻole me ke ʻano kemika H3PO3.He pauka keʻokeʻo keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol, a hoʻoheheʻe mālie ʻia i orthophosphate i ka ea.ʻO ka Phosphite he ʻakika dibasic, ʻoi aku ka ikaika o kona ʻakika ma mua o ka waikawa phosphoric, he waiwai hoʻemi ikaika, maʻalahi e hoʻemi i nā ion kālā (Ag +) i ke metala kālā (Ag), hiki ke hoʻemi i ka sulfuric acid i ka sulfur dioxide.Loaʻa iā ia ka hygroscopicity ikaika a me ka deliviousness, a he corrosive.Hoʻohana nui ʻia ʻo Phosphite ma ke ʻano he mea hoʻohaʻahaʻa, ka mea hoʻomālamalama nylon, akā hoʻohana pū ʻia e like me ka phosphite maka, nā pesticide intermediates a me nā mea mālama wai phosphorus organik i nā mea maka.
Nā waiwai:pauda kristal keʻokeʻo.Hiki ke hoʻoheheʻe ʻia i ka wai a me ka waiʻona.Density: 1.651g/cm3, ka helu heheʻe: 73 ℃, kahi e hoʻolapalapa ai: 200 ℃.
HOOLAHA:
1.ʻakika phosphorusHoʻohana ʻia e hana i ka paʻakai phosphate fertilizer e like me ka potassium phosphite, ammonium phosphite a me ka calcium phosphite.Hoʻokomo ikaika ia i ka hoʻomākaukau ʻana i nā phosphites e like me aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) a me 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), i loaʻa. ka hoʻohana ʻana i ka mālama wai ma ke ʻano he unahi a i ʻole corrosive inhibitor.Hoʻohana ʻia ia i nā hopena kemika ma ke ʻano he mea hoʻemi.Hoʻohana ʻia kona paʻakai, lead phosphite e like me PVC stabilizer.Hoʻohana ʻia ia ma ke ʻano he precursor i ka hoʻomākaukau ʻana i ka phosphine a ma ke ʻano he mea waena i ka hoʻomākaukau ʻana i nā pūhui phosphorus ʻē aʻe.
2.ʻakika phosphorus(H3PO3, orthophosphorous acid) hiki ke hoʻohana ʻia ma ke ʻano he ʻāpana ʻāpana no ka hoʻohui ʻana o kēia mau mea:
α-aminomethylphosphonic acids ma o Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids ma o ka amidoalkylation a me ka hydrolysis
N-protected α-aminophosphonic acids (phospho-isosteres o nā ʻakika amino maoli) ma o ka hopena amidoalkylation
3. Hoʻohana ʻenehana: Ua hoʻomohala ʻia kēia ʻohi a ua hoʻohana mua ʻia ma ke ʻano he ʻohi kikoʻī no ka cassiterite mai nā ores me ka haku mele paʻakikī. ie cassiterite, ilmenite a me pyrochlore).Kakaikahi ka ike e pili ana i ka hana a keia poe ohi.Ua hōʻike ʻia nā haʻawina liʻiliʻi i hana ʻia me ka cassiterite a me ka rutile ores e hana ana kekahi o kēia mau mea hōʻiliʻili i ka huʻu voluminous akā koho loa.
Hana hana:
ʻO nā ʻano hana hana ʻoihana ka trichloroic phosphorus a me ka paʻakai phosphoric acid.Hoʻohui mālie ke ʻano hydrolysis i ka wai i ka hopena hydrolysis ma lalo o ka hui ʻana o ka trichloride e hoʻohua i ka waikawa sub-phosphoric.Ma hope o ka hoʻomaʻemaʻe ʻana, ka ChemicalBook anuanu, hana ʻia ka crystallization a me ka discoloration, a hana ʻia ka huahana i hoʻopau ʻia.ʻO kāna PCI3 + 3H2O → H3PO3 + 3HCL e hana i ka hydrogen chloride recycling i ka wā o ke kaʻina hana, hiki ke hana ʻia i loko o ka waikawa hydrochloric.
Palekana:
ʻO nā hiʻohiʻona pilikia o ke ahi: ma ka H hole agent combustible;Hoʻopau ka wela i nā uahi phosphorus oxide ʻona.
ʻO nā hiʻohiʻona o ka mālama ʻana a me ka lawe ʻana: wīwī hale kūʻai haʻahaʻa haʻahaʻa maloʻo;E kūʻai kaʻawale mai ka H pore-releasing agent a me ka alkali.
Hoʻopili: 25kg / ʻeke
Ka mālama ʻana: Mālama ʻia i loko o kahi paʻa maikaʻi, kūpaʻa māmā, a pale i ka maʻu.
