Tlhaloso

Phosphorous acid, H3PO3, e na le diprotic (e kopanya li-proton tse peli habonolo), eseng triprotic joalokaha ho ka boleloa ke foromo ena.Phosphorous acid ke karolo e bohareng ea ho lokisoa ha metsoako e meng ea phosphorus.Hobane ho lokisoa le ho sebelisoa ha "phosphorous acid" ha e le hantle ho amana haholo le tautomer e kholo, phosphonic acid, hangata e bitsoa "phosphorous acid". ho bontsha sebopeho sa yona sa diprotic.

Tšebeliso ea phosphorus acid

1.Phosphorous acid e sebelisoa ho hlahisa letsoai la phosphate ea manyolo joaloka potassium phosphite, ammonium phosphite le calcium phosphite.E ameha ka mafolofolo ho lokiseng li-phosphite tse kang aminotris(methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) le 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), e fumanang tshebediso ya pheko ya metsi joalo ka sekala kapa sethiba se senyang.E boetse e sebelisoa liketsong tsa lik'hemik'hale e le ntho e fokotsang.Letsoai la eona, lead phosphite e sebelisoa e le PVC stabilizer.E boetse e sebelisoa e le selelekela sa ho lokisoa ha phosphine hape e le setsi sa ho lokisa metsoako e meng ea phosphorus.
2.Phosphorous acid (H3PO3, orthophosphorous acid) e ka sebelisoa e le e 'ngoe ea likarolo tsa karabelo bakeng sa motsoako oa tse latelang:
α-aminomethylphosphonic acid ka Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acid ka amidoalkylation e lateloang ke hydrolysis
N-e sirelelitsoeng α-aminophosphonic acid (phospho-isosteres ea li-amino acid tsa tlhaho) ka karabelo ea amidoalkylation
