|Section3= }} Methylphosphonic acid is an organophosphorus compound with the chemical formula. CH3P(O)(OH)2. The phosphorus center is tetrahedral and is bonded to a methyl group, two OH groups and an oxygen. Methylphosphonic acid is a white, non-volatile solid that is poorly soluble in organic solvent but soluble in water and common alcohols.〔(【引用サイトリンク】url=http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?cid=13818 )〕 ==Preparation== Methylphosphonic acid can be prepared via the Michaelis-Arbuzov reaction from triethylphosphite: :CH3Cl + P(OC2H5)3 → CH3PO(OC2H5)2 The dialkylphosphonate is then treated with chlorotrimethylsilane: :CH3PO(OC2H5)2 + 2 Me3SiCl → CH3PO(OSiMe3)2 + 2 ClC2H5 The siloxyphosphinate is then hydrolyzed: :CH3PO(OSiMe3)2 + 2H2O → CH3PO(OH)2 + 2 HOSiMe3 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「methylphosphonic acid」の詳細全文を読む スポンサード リンク
