YieldReaction ConditionsOperation in experiment
With acetic anhydride; acetic acid; In water; EXAMPLE 5 40.8 g (0.4 mol) of acetic anhydride were cooled to 10 C. After this, 16.4 g (0.2 mol) of phosphorous acid were introduced in the course of 5 minutes, with stirring and cooling. 17.8 g (0.2 mol) of <strong>[625-51-4]N-hydroxymethylacetamide</strong> were subsequently added dropwise at 10 C. in the course of 10 minutes. After this, the mixture was first allowed to come to room temperature and then refluxed for 2.5 hours. The mixture was subsequently cooled. 10 ml of water were then added in portions. After this, the mixture was kept under reflux for 1 hour. After this, a mixture of 10 ml of acetic acid and 1.5 ml of water was added, and stirring was continued. After crystallisation and filtration with suction, 16.3 g (53% of theory) of acetylaminomethanephosphonic acid of a melting point of 188-194 C. were obtained.

YieldReaction ConditionsOperation in experiment
In water; acetic acid; EXAMPLE 4 20 g (0.225 mol) of <strong>[625-51-4]N-hydroxymethylacetamide</strong> were dissolved in 20 ml of acetic acid and cooled to 5 C. under a nitrogen atmosphere and with stirring. 12.4 g (0.113 mol) of diphosphorus trioxide (P2 O3) were then added dropwise at 5 to 10 C. with stirring during the course of 20 minutes. The mixture was then stirred without cooling until room temperature was reached. It was then heated to reflux for 31/2 hours. It was then cooled. 2 g (0.11 mol) of water were then added dropwise with stirring, the temperature rising to 35 C. After cooling, the acetic acid was removed under reduced pressure and with continuous warming to 95 C. The crystalline residue was digested with ethanol. 26 g of crude acetylaminomethanephosphonic acid having a melting point of 171-175 C. were obtained. After recrystallization from 88% strength aqueous acetic acid, 19 g (55% of theory) of acetylaminomethanephosphonic acid having a melting point of 186 to 90 C. were obtained. The CHNP elemental analysis of a sample gave: C3 H8 NO4 P calc.: 23.53% C 5.23% H 9.15% N 20.26% P, (153) found: 22.6% C 5.1% H 8.7% N 20.4% P.
