- Preparation method of aluminum alkoxide
-
The invention discloses a preparation method of aluminum alkoxide. An excessive amount of Al-N alloy powder is added into alcohol with the number of carbon atoms being 1-8, a reaction is conducted for1-3 hours at room temperature, and aluminum alkoxide is obtained after solid and liquid are separated, wherein the Al-N alloy powder is prepared through a gas atomization mode, and prepared from theraw materials of aluminum and a small amount of alloy elements which can be repeatedly used. No catalyst is needed and no heating is needed in the preparation method, the reaction condition is mild, aluminum alkoxide can be generated in one step at room temperature, the preparation method is simple and efficient, and the cost is low; and meanwhile, the safety coefficient in the production and using processes is high, transportation and storage are facilitated. In addition, harmful substances containing mercury or iodine are not used in the preparation method, and no pollution is generated to the environment.

- A METHOD FOR THE PREPARATION OF LOWER ALUMINUM ALKOXIDE BY GAS-SOLID PHASE REACTION
-
The invention provides a novel process for the preparation of lower aluminum alkoxide of high purity by gas-solid phase reaction, wherein the lower aluminum alkoxide is prepared by reacting gaseous lower alkyl alcohol with solid metal aluminum. By using the process of the invention, the process for the production of lower aluminum alkoxide is simplified, investment on equipments and energy consumption is reduced, and it is friendly to the environment. This process solves the following problems that, for example, the production of aluminum n-butoxide has complicate processes, excessively high cost, relatively low safety factor, catalyst pollution, etc..
