Magnesium-aluminum composite oxide and preparation method thereof
The invention relates to the field of magnesium-aluminum composite oxide preparation, and discloses a magnesium-aluminum composite oxide and a preparation method thereof. The method comprises the following steps: (1) under an anhydrous condition, carrying out first reaction on an aluminum simple substance and first fatty alcohol to obtain a material containing alkoxy aluminum; (2) under the action of a catalyst, carrying out a second reaction on the material containing alkoxy aluminum obtained in the step (1), a magnesium elementary substance and second fatty alcohol under an anhydrous condition; (3) hydrolyzing the reaction product in the step (2) to obtain magnesium-aluminum bimetal alkoxide, and then optionally drying and roasting to obtain a magnesium-aluminum composite oxide; wherein the first fatty alcohol and the second fatty alcohol respectively and independently comprise n-amyl alcohol and optional n-hexyl alcohol. According to the preparation method of the magnesium-aluminum composite oxide, provided by the invention, the high-purity magnesium-aluminum composite oxide can be obtained without subsequent purification treatment, and meanwhile, the preparation method has the advantages of short initiation time and short reaction time.
本发明涉及镁铝复合氧化物制备领域，公开了一种镁铝复合氧化物及其制备方法。所述方法包括以下步骤：(1)在无水条件下，将铝单质和第一脂肪醇进行第一反应，得到含烷氧基铝的物料；(2)在催化剂的作用下，将步骤(1)得到的含烷氧基铝的物料、镁单质和第二脂肪醇在无水条件下进行第二反应；(3)将步骤(2)的反应产物进行水解，得到镁铝双金属醇盐，然后进行任选地干燥和焙烧，得到镁铝复合氧化物；其中，所述第一脂肪醇和第二脂肪醇各自独立地包括正戊醇和任选地正己醇。通过本发明提供的镁铝复合氧化物的制备方法无需经过后续提纯处理即可得到高纯度的镁铝复合氧化物，同时具有引发时间短和反应时间短的优势。
