Gaosi Mea Tau Lelei Fofosa Acid CAS:13598-36-2
Fa'amatalaga
O le phosphorous acid, H3PO3, e diprotic (e faigofie ona fa'a'ona i protons se lua), ae le o le triprotic e pei ona fa'ailoa mai e lenei fua fa'atatau.O le phosphorous acid e avea o se mea faʻavauvau i le sauniuniga o isi phosphorous compound.Talu ai o sauniuniga ma le faʻaaogaina o le "phosphorous acid" e sili atu ona taua i le tautomer tele, phosphonic acid, e masani ona taʻua o le "phosphorous acid". Phosphorous acid o loʻo i ai le vailaʻau H3PO3, lea e sili ona faʻaalia o le HPO (OH) 2. e fa'aalia lona uiga diprotic.

Fa'aaogāga ole Phosphorous Acid
1. Phosphorous acid o loʻo faʻaaogaina e gaosia ai le masima phosphate fertilizer e pei o le potassium phosphite, ammonium phosphite ma le calcium phosphite.O loʻo aʻafia malosi i le sauniuniga o phosphites e pei o aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) ma le 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), lea e maua. fa'aoga ile vai vai e fai ma fua po'o se fa'ato'a pala.E fa'aaogaina fo'i i vaila'au fa'ainisinia e fai ma sui fa'aitiitia.O lona masima, taʻitaʻi phosphite e faʻaaogaina e avea ma PVC stabilizer.E faʻaaogaina foʻi e avea o se mea muamua i le sauniuniga o le phosphine ma o se mea faʻapitoa i le sauniuniga o isi mea faʻapipiʻi phosphorus.
2. Phosphorous acid (H3PO3, orthophosphorous acid) e mafai ona faʻaaogaina e avea o se tasi o vaega tali mo le faʻapipiʻiina o mea nei:
α-aminomethylphosphonic acids e ala i le Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids e ala i le amidoalkylation sosoo ai ma le hydrolysis
N-puipuia α-aminophosphonic acids (phospho-isosteres of natural amino acids) e ala i le tali amidoalkylation
3. Fa'aoga fa'apisinisi: O lenei aoina na fa'atupuina talu ai nei ma sa fa'aaoga muamua e pei o le aoina fa'apitoa mo cassiterite mai ores ma fa'alavelave gague composition. I luga o le fa'avae o le phosphonic acid, Albright ma Wilson na fa'atupuina le tele o aoina e masani lava mo le fa'afefe o minerale oxidic ( ie cassiterite, ilmenite ma pyrochlore).E itiiti lava se mea e iloa e uiga i le faatinoga o nei tagata aoina.O su'esu'ega fa'atapula'a na fa'atinoina i le cassiterite ma le rutile ores na fa'aalia ai o nisi o nei tagata aoina e maua mai ai le fue tele ae sa matua filifilia lava.
