| titleOfInvention | A kind of hydroxybenzylidene diphosphonic acid and preparation method thereof |
| abstract | The invention belongs to the field of preparation methods of organic compounds, and in particular relates to a hydroxybenzylidene diphosphonic acid and a preparation method thereof. The structural formula of the hydroxybenzylidene diphosphonic acid is: Using phosphorous acid and benzoyl chloride as raw materials, heating and condensation reaction under normal pressure or slight negative pressure produces crude hydroxybenzylidene diphosphonic acid, and then produces hydroxybenzylidene diphosphine through hydrolysis, suction filtration, drying and other processes Sour finished product. The invention has the advantages of simple process route, convenient operation, less preparation facilities and less discharge of "three wastes". |
