Mea Hana Waikawa Phosphorous Kumukūʻai Maikaʻi CAS:13598-36-2 Kiʻi i Hōʻike ʻia

wehewehe pōkole:

ʻO ka waikawa phosphorous kahi mea waena i ka hoʻomākaukau ʻana o nā hui phosphorous ʻē aʻe. ʻO ka waikawa phosphorous kahi mea maka e hoʻomākaukau ai i nā phosphonates no ka mālama ʻana i ka wai e like me ka hao a me ka manganese control, ka pale ʻana a me ka wehe ʻana i ka unahi, ka pale ʻana i ka pala a me ka hoʻopaʻa ʻana o ka chlorine. Ke kūʻai nui ʻia nei nā paʻakai metala alkali (phosphites) o ka waikawa phosphorous ma ke ʻano he fungicide mahiʻai (e like me Downy Mildew) a i ʻole he kumu maikaʻi loa o ka meaʻai phosphorous mea kanu. Hoʻohana ʻia ka waikawa phosphorous i ka hoʻopaʻa ʻana i nā hui no nā mea plastik. Hoʻohana ʻia ka waikawa phosphorous no ka pale ʻana i ka mahana kiʻekiʻe o nā ʻili metala i hiki ke pala a hana i nā lubricants a me nā mea hoʻohui lubricant.

ʻO ka waikawa phosphorous, ʻo H3PO3, he diprotic (hoʻohui koke i ʻelua protons), ʻaʻole triprotic e like me ka mea i manaʻo ʻia e kēia formula. ʻO ka waikawa phosphorous he waena i ka hoʻomākaukau ʻana o nā hui phosphorous ʻē aʻe. No ka mea, ʻo ka hoʻomākaukau ʻana a me ka hoʻohana ʻana o ka "phosphorous acid" e pili pono ana i ka tautomer nui, ka waikawa phosphonic, ua kapa pinepine ʻia ʻo "phosphorous acid". Loaʻa i ka waikawa phosphorous ke ʻano kemika H3PO3, kahi i hōʻike maikaʻi ʻia ʻo HPO(OH)2 e hōʻike i kona ʻano diprotic.

Nā Hoʻohana o ka Waikawa Phosphorous

1. Hoʻohana ʻia ka waikawa phosphorous 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, ke 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. Hiki ke hoʻohana ʻia ka waikawa phosphorous (H3PO3, waikawa orthophosphorous) 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.
