Method for preparing formylphosphonic acid |
| abstract |
A process for the manufacture of formylphosphonic acid derivatives is reported. An aminomethylphosphonic acid substrate is contacted with a reagent selected from the group consisting of water, an alcohol, a phenol compound, and mixtures thereof and an oxidizing gas in the presence of a catalyst to form a reaction product mixture containing a formylphosphonic acid derivative and the conditions under which said contacting is carried out are controlled so that no more than 50% of the formylphosphonic acid derivative formed in the reaction product mixture is consumed by reaction with the reagent. |
