Participants

Reaction Conditions

Reaction Steps

Magnesium hydroxide (11.66 g.; 0.2 mole) suspended in water (20 cc.) is added to N,N'-diacetylornithine (172.8 g.; 0.8 mole) dissolved in distilled water (1,200 cc.) at 60° C. The reaction mixture is heated and stirred at 60° C for 30 minutes. Aluminium isopropoxide (81.6 g.; 0.4 mole) suspended in isopropanol (100 cc.) is added, and the mixture is then stirred and heated at 60° C for 30 minutes. After treatment of the reaction mixture as in Example 1, a mixed aluminium magnesium salt of N,N'-diacetyl-ornithine (175 g.) is obtained in the form of a white powder corresponding to the formula: ##EQU6## Al% = 5.45 (theory: 5.35) and Mg% = 2.36 (theory: 2.42).
