Patent ID: 8546557

Claim:
A method of making an organophosphate compound, comprising admixing a compound of formula I-A and a compound of formula II-A to form a compound of formula III, wherein formula I-A is represented by: wherein: R 1 is C 1 -C 4 alkyl; R 2 represents independently for each occurrence H or an alkali metal; or two occurrences of R 2 taken together form an alkaline earth metal; and x is 0, 1, or 2; formula II-A is represented by: wherein: R 3 and R 4 , taken together with the nitrogen atom to which they are attached, form a 3 to 6 membered heterocyclic ring: R 5 represents independently for each occurrence H or an alkali metal; or two occurrences of R 5 taken together form an alkaline earth metal; y is 0, 1, or 2; and provided that the sum of x and y is 2; and formula III is represented by: wherein: R 6 is C 1 -C 4 alkyl; and R 7 represents independently for each occurrence H or an alkali metal; or two occurrences of R 7 taken together form an alkaline earth metal.
