Usoro mmepụta
Ụzọ mmepụta mmepụta ihe gụnyere phosphorus trichloride hydrolysis na usoro phosphite.
Usoro hydrolysis ji nwayọọ nwayọọ na-agbakwụnye mmiri dropwise na phosphorus trichloride n'okpuru mkpali maka mmeghachi omume hydrolysis iji mepụta phosphorous acid, nke a nụchara anụcha Chemicalbook, jụrụ oyi na crystallized, na decolored iji nweta phosphorous acid okokụre.
Usoro mmepụta nke PCI3 + 3H2O → H3PO3 + 3HCl na-emepụta hydrogen chloride maka imegharị ihe, nke a pụrụ ime ka ọ bụrụ hydrochloric acid.
Nkwụsi ike metụtara
1. Ọ na-eji nwayọọ nwayọọ oxidized n'ime orthophosphoric acid na ikuku na decomrated n'ime orthophosphoric acid na phosphine (ukwuu na-egbu egbu) mgbe kpụ ọkụ n'ọnụ ruo 180 ℃.Phosphorous acid bụ dibasic acid, acidity ya dị ntakịrị ike karịa phosphoric acid, ọ nwekwara ike reucibility siri ike, nke nwere ike belata Ag ion na ọlaọcha ọla na sulfuric acid na sulfur dioxide.Ike hygroscopicity na deliquescence, corrosive.Nwere ike ịkpata ọkụ.Na-akpasu iwe na akpụkpọ ahụ.Edobere ya n'ikuku, ọ na-agbaze ma na-agbaze ngwa ngwa na mmiri.Mgbe okpomọkụ dị elu karịa 160 ℃, H3PO4 na PH3 na-eme.
