    摘要： N-acylaminomethylphosphonic acid is prepared from an N-methylolamide compound and a phosphorus trihalide. The starting compounds are mixed and heated in an aprotic solvent in the presence of water in a 0.25 to 2.5 times molar amount relative to the phosphorus trihalide at 60.degree. to 160.degree. C., and the reaction mixture is contacted with water. The N-methylolamide compound is a compound selected from the group consisting of N-methylol-lower alkylamides and N-methylolarylamides. The phosphorus trihalide is preferably phosphorus trichloride. As the aprotic solvent is used one or more of hydrocarbons, halogenated hydrocarbons, ethers, polyethers, nitriles, and aromatic nitro compounds. The mixing may be carried out at a temperature of 60.degree. C. The water present at the initiation of the reaction is in a 1.0 to 1.8 times molar amount relative to the phosphorus trihalide.
