ʻO ka hypophosphorous acid kahi mea hoʻohaʻahaʻa.ʻAka monobasic ikaika.He ʻakika ka hoʻonā wai a hiki ke hoʻoheheʻe mālie ʻia i ka ea ma ke ana wela.Hiki ke hoʻopau ʻia ka hoʻopili ʻana me ka H pore forming agent.ʻO ke ahi ma muli o ka hopena ikaika me nā oxidants.ʻO ke kinoea Phosphine, he mea ʻawaʻawa loa ia ma muli o ka hoʻoheheʻe ʻana o ka wela nui, a pahū.ʻAiʻino.Hoʻohui pinepine ʻia ka hypophosphorous acid i nā mea inu ʻoluʻolu no ka mea ʻaʻole i komo.No laila, liʻiliʻi ka pōʻino, akā ʻo ka Hypophosphorous acid me kahi koʻikoʻi ikaika e hōʻeha i ka ʻōpū o ka ʻōpū.ʻO ka hoʻomehana ʻana i ka waika paʻa i 130-140 ℃ hopena i ka disproportionation a me ka decomposition i PH3 a me H3PO4.

ʻO ka Hypophosphorous acid, i ʻike ʻia ʻo "hypophosphite", ʻaila aila ʻole a i ʻole deliquescent crystal, he huahana koʻikoʻi o ka ʻoihana kemika maikaʻi.Hoʻohana nui ʻia ʻo ia ma ke ʻano he mea hōʻemi no ka plating electroless e pale i ka discoloration o ka resin phosphoric acid, a me ka catalyst a me ka refrigerant no ka hopena esterification, ʻoi aku hoʻi no ka hana ʻana o ka sodium hypophosphite kiʻekiʻe.Nui nā ʻano hoʻomākaukau, ma waena o nā ʻano hoʻomākaukau maʻamau i ka ʻoihana ʻo ke ʻano resin exchange ion a me ke ʻano Electrodialysis.

Hoʻohana

1. Hoʻohana ʻia ka hypophosphorous acid ma ke ʻano he mea hoʻohaʻahaʻa no ka plating electroless;
2. Hiki ke hoʻohana 'ia e pale i ka discoloration o ka phosphoric acid resin;
3. Hoʻohana ʻia ia e like me ka esterification catalyst, ka refrigerant;
4. Hoʻohana ʻia ia e hana i ka hypophosphite, nā paʻakai sodium, nā paʻakai manganese, nā paʻakai hao e hoʻohana mau ʻia e like me nā mea hānai;
5. Hoʻohana ʻia ka Hypophosphorous acid i ka lāʻau lapaʻau a ma ke ʻano he mea hoʻohaʻahaʻa, ka hoʻoholo ʻana o ka arsenic, tellurium a me ka hoʻokaʻawale ʻana o tantalum, niobium a me nā mea hou aku.
6. He mea hoʻemi ikaika ia, hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i ka sodium hypophosphite, calcium phosphate a me nā hypophosphite ʻē aʻe.
7. Hiki ke hoʻohana no ka ʻauʻau plating.Nā lāʻau lapaʻau.mea hoemi.nā mea hoʻopaʻi maʻamau.
8. He mea ho'ēmi ikaika ia, hiki ke hoʻohanaʻia i ka hanaʻana i ka sodium hypophosphite, calcium phosphate a me nā hypophosphite'ē aʻe.
9. Hoʻohana nui ʻia kēia huahana ma ke ʻano he mea hoʻohaʻahaʻa, ʻo Ag, Cu, Ni, Hg a me nā metala ʻē aʻe i hoʻemi ʻia i ka metala pili, no ka hōʻoia ʻana o As, Nb, Ta a
