    • PURPOSE: A preparation method of basic aluminum magnesium hydroxycarbonate is provided which uses aluminum hydroxide gel and magnesium hydroxide gel instead of water-soluble salts or water-insoluble hydroxide as an aluminum and magnesium source and ammonium carbonate or ammonium bicarbonate as a carbon source. CONSTITUTION: Basic aluminum magnesium hydroxycarbonate of formula I is prepared by diluting aluminum hydroxide gel in water and reacting with one or more compounds selected from ammonium carbonate or ammonium bicarbonate at 80-100°C. The formula I is Al2Mg6(OH)2.4H2O. The method uses aluminum hydroxide gel and magnesium hydroxide gel as an aluminum such that the reaction is advanced with a high reactivity without impurities and ammonium carbonate or ammonium bicarbonate as a carbon source such that it is unnecessary to use an excess amount of carbon dioxide and thereby the reaction is accelerated much more.
    • 目的:提供碱性铝羟基碳酸镁的制备方法,其使用氢氧化铝凝胶和氢氧化镁凝胶代替水溶性盐或水不溶性氢氧化物作为铝和镁源,碳酸铵或碳酸氢铵作为碳源。 构成:式I的碱性铝羟基碳酸镁通过在水中稀释氢氧化铝凝胶并与80-100℃下与一种或多种选自碳酸铵或碳酸氢铵的化合物反应来制备。 式I是Al 2 Mg(OH)2·4H 2 O。 该方法使用氢氧化铝凝胶和氢氧化镁凝胶作为铝,使得反应进行而没有杂质的高反应性,碳酸铵或碳酸氢铵作为碳源,使得不需要使用过量的二氧化碳,从而 反应加速得更多。
