Asịd phosphorous, H3PO3, bụ diprotic (na-eme ka proton abụọ dị iche iche dị ion), ọ bụghị triprotic dịka usoro a si kwuo. Asịd phosphorous dị ka ihe dị n'etiti nkwadebe nke ihe ndị ọzọ na-emepụta phosphorous. Ebe ọ bụ na nkwadebe na ojiji nke "phosphorous acid" metụtara tautomer bụ isi, phosphonic acid, a na-akpọkarị ya "phosphorous acid". Asịd phosphorous nwere usoro kemịkalụ H3PO3, nke a na-egosipụta nke ọma dị ka HPO(OH)2 iji gosipụta agwa diprotic ya.

Ngwa nke Phosphorus Acid

1. A na-eji phosphate acid emepụta nnu phosphate fatịlaịza dịka potassium phosphite, ammonium phosphite na calcium phosphite. Ọ na-arụsi ọrụ ike na nkwadebe nke phosphites dịka aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) na 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), nke na-enweta ojiji na ọgwụgwọ mmiri dị ka ihe mgbochi ma ọ bụ ihe mgbochi mmebi. A na-ejikwa ya na mmeghachi omume kemịkalụ dị ka ihe na-ebelata ihe. A na-eji nnu ya, lead phosphite dị ka ihe na-eme ka PVC sie ike. A na-ejikwa ya dị ka ihe na-ebute ụzọ na nkwadebe nke phosphine na dị ka ihe etiti na nkwadebe nke ihe ndị ọzọ phosphorus.
2. A pụrụ iji asịd phosphorous (H3PO3, orthophosphorous acid) dị ka otu n'ime ihe mmeghachi omume maka njikọta nke ihe ndị a:
α-aminomethylphosphonic asịd site na Mmeghachi omume Mannich-Type Multicomponent
1-aminoalkanephosphonic acid site na amidoalkylation wee sochie hydrolysis
Acid α-aminophosphonic nke N-echebe (phospho-isosteres nke amino acid eke) site na mmeghachi omume amidoalkylation
