일반 설명
Phosphorous acid (or phosphonic acid) is a phosphorus oxoacid commonly used as an intermediate in chemical synthesis for the production of various phosphorus compounds. It is also used as a strong reducing agent in organic synthesis.
애플리케이션
Phosphorous acid (H3PO3, orthophosphorous acid) may be used as one of the reaction components for the synthesis of the following:
- α-aminomethylphosphonic acids via Mannich-Type Multicomponent Reaction
- 1-aminoalkanephosphonic acids via amidoalkylation followed by hydrolysis
- N-protected α-aminophosphonic acids (phospho-isosteres of natural amino acids) via amidoalkylation reaction

In order to remove metal ions from wastewaters, thermosensitive copolymers bearing sorption properties toward metal cations were prepared by free radical copolymerization between the N-n-propylacrylamide (NnPAAm) and the (dimethoxyphosphoryl)methyl 2-methylacrylate (MAPC1), followed by a hydrolysis of the phosphonated esters into
