Reaction Steps

Aluminum hydroxide (1.17 grams, 0.015 mole) was combined with 7.5 grams (g) (0.045 mole) of N-phosphonomethylglycine in a 200 milliliters (ml) flask containing 60 ml of deionized water. The flask was equipped with a magnetic stirrer. This solution was heated at reflux temperature for one hour and then let stand overnight at room temperature. The reaction mixture the next day contained more solid material after cooling overnight. The solution was again heated at reflux for 3 more hours, and then cooled to room temperature. The material was then filtered to remove the solids and the aqueous filtrate was stripped at 30° C. and 1 mm of mercury. The residue was 8.0 g of a white powder which was water-soluble, having a melting point of 231° C. The white powder was subjected to standard analytical procedures and the subject compound was confirmed as one part aluminum and four parts of the N-phosphonomethylglycine anion.
