ʻAkika Phosphorous，he hui inorganic me ke ʻano kemika H3PO3. He pauka kristal keʻokeʻo ia, maʻalahi ke hoʻoheheʻe ʻia i ka wai a me ka ethanol, a hoʻomake mālie ʻia i orthophosphate i ka lewa. He waikawa dibasic ka Phosphite, ʻoi aku ka ikaika o kona acidity ma mua o ka waikawa phosphoric, he waiwai hoʻemi ikaika kona, maʻalahi ke hoʻemi i nā ion kālā (Ag+) i ka metala kālā (Ag), hiki ke hoʻemi i ka waikawa sulfuric i ka sulfur dioxide. Loaʻa iā ia ka hygroscopicity ikaika a me ka deliviousness, a he corrosive. Hoʻohana nui ʻia ka Phosphite ma ke ʻano he mea hoʻemi, he mea hoʻomālamalama nylon, akā hoʻohana ʻia hoʻi ma ke ʻano he mea maka phosphite, nā mea waena pesticide a me nā mea mālama wai phosphorus organik.
Nā Waiwai:Pauka kristal keʻokeʻo. Hiki ke hoʻoheheʻe ʻia i ka wai a me ka waiʻona. Ka nui o ka paʻa: 1.651g/cm3, kiko heheʻe: 73℃, kiko paila: 200℃.
PALAPALA NOI:
1.ʻAkika phosphorousHoʻohana ʻia e hana i ka paʻakai phosphate mea hoʻouluulu e like me ka potassium phosphite, ammonium phosphite a me ka calcium phosphite. Ke komo ikaika nei ia i ka hoʻomākaukau ʻana o 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), kahi e loaʻa ai ka hoʻohana ʻana i ka mālama ʻana i ka wai ma ke ʻano he unahi a i ʻole ka mea hoʻopale corrosive. Hoʻohana ʻia hoʻi ia i nā hopena kemika ma ke ʻano he mea hoʻemi. Hoʻohana ʻia kona paʻakai, alakaʻi phosphite ma ke ʻano he mea hoʻopaʻa PVC. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea mua i ka hoʻomākaukau ʻana o ka phosphine a ma ke ʻano he waena i ka hoʻomākaukau ʻana o nā hui phosphorus ʻē aʻe.
2.ʻAkika phosphorous(H3PO3, waikawa orthophosphorous) hiki ke hoʻohana ʻia ma ke ʻano he hoʻokahi o nā ʻāpana hopena no ka hana ʻana o kēia mau mea:
nā waikawa α-aminomethylphosphonic ma o ka Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids ma o ka amidoalkylation i ukali ʻia e ka hydrolysis
Nā waikawa α-aminophosphonic i pale ʻia e N (phospho-isosteres o nā waikawa amino kūlohelohe) ma o ka hopena amidoalkylation
3. Nā hoʻohana ʻoihana: Ua hoʻomohala ʻia kēia mea hōʻiliʻili i kēia manawa a ua hoʻohana nui ʻia ma ke ʻano he mea hōʻiliʻili kūikawā no ka cassiterite mai nā ores me ka haku mele gangue paʻakikī. Ma ke kumu o ka waikawa phosphonic, ua hoʻomohala ʻo Albright lāua ʻo Wilson i kahi ʻano o nā mea hōʻiliʻili no ka flotation o nā minelala oxidic (ʻo ia hoʻi ka cassiterite, ilmenite a me pyrochlore). ʻAʻole ʻike nui ʻia e pili ana i ka hana a kēia mau mea hōʻiliʻili. Ua hōʻike ʻia nā haʻawina palena i hana ʻia me nā ores cassiterite a me rutile e hana ana kekahi o kēia mau mea hōʻiliʻili i ka froth voluminous akā ua koho nui ʻia.
ʻAno hana:
ʻO nā ʻano hana hana ʻoihana e komo pū me ka phosphorus trichloroic a me ka paʻakai waikawa phosphoric. Hoʻohui mālie ke ʻano hydrolysis i ka wai i ka hopena hydrolysis ma lalo o ke kāwili ʻana o ka trichloride e hana i ka waikawa sub-phosphoric. Ma hope o ka hoʻomaʻemaʻe ʻana, hana ʻia ka crystallization a me ka discoloration ma o ChemicalBook anuanu, a hana ʻia ka huahana i hoʻopau ʻia. ʻO kāna PCI3+3H2O → H3PO3+3HCL e hana hou i ka hydrogen chloride i ka wā o ke kaʻina hana, hiki ke hana ʻia i ka waikawa hydrochloric.
Palekana:
Nā ʻano pilikia lapalapa: hiki ke ʻā i loko o ka lua H; Hoʻopau ka wela i nā uahi phosphorus oxide ʻawahia.
Nā ʻano o ka mālama ʻana a me ka halihali: ea hale kūʻai i ka mahana haʻahaʻa a maloʻo; E mālama kaʻawale mai ka mea hoʻokuʻu pore H a me ka alkali.
Hoʻopili ʻana: 25kg/ʻeke
Ka mālama ʻana: E mālama i loko o kahi pani paʻa, pale i ka mālamalama, a pale mai ka makū.
