PREPARATION OF A HYDROXYALKYL PHOSPHONIC ACID |
| 摘要 |
The present invention is a process for converting a phosphonate to a hydroxyalkyl phosphonic acid comprising the step of contacting together water, the phosphonate, and a sulfonated or phosphonated heterogeneous catalyst under conditions sufficient to convert at least 50% of the phosphonate to the hydroxyalkyl phosphonic acid. The process of the present invention provides a way of preparing hydroxyalkyl phosphonic acids safely and economically, without corrosive effects. |

1. A process for converting a phosphonate, which is a hydroxyalkyl- or acyloxyalkyl-phosphonate, to a hydroxyalkyl phosphonic acid comprising the step of contacting together water, the phosphonate, and a sulfonated or phosphonated heterogeneous catalyst under conditions sufficient to convert at least 50% of the phosphonate to the hydroxyalkyl phosphonic acid. |
