2 Methods of producing of basic aluminium magnesium carbonate:
1. A suspension of aluminum hydroxide (9.57 g, corresponding to 5.09 g of Al2O3 0.05 mol), magnesium hydroxide of 92.09% purity (18.87 g; 0.3 mol), concentrated ammonium hydroxide (4.89 ml; 0.33 mol) and water (500 ml) was boiled under reflux for 6 h while a stream of carbon dioxide was passed through the mixture. Then the reaction mixture was cooled, and the insoluble compound was filtered off, washed several times with water and dried in vacuum at a temperature of 60°C. Basic aluminum magnesium carbonate (31.1 g) was obtained.
2. A suspension of aluminium hydroxide (9.57 g, corresponding to 5.09 g of Al2O3 0.05 mol) magnesium hydroxide of 92.09% purity (18.87 g; 0.3 mol), triethylamine (33.4 g; 0.33 mol) and water (500 ml) was boiled under reflux for 8 h while a stream of carbon dioxide was passed through the mixture. After cooling, the insoluble compound was filtered off, washed several times with water and dried at 60°C under reduced pressure. Basic aluminum magnesium carbonate (30.8 g) was obtained.
