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..

Abrégé

It is provided in the invention a process for the preparation of a fast solidifying aluminum isopropoxide of high purity, comprising providing lower aluminum alkoxide, and adding solid lower aluminum alkoxide as a solidifying agent into the liquid aluminum to yield the solidified lower aluminum alkoxide. Specificially, when the temperature of the liquid lower aluminum alkoxide is lowered to 40-85℃, the solid lower aluminum alkoxide is added with agitation as the solidifying agent. Generally, the solid lower aluminum alkoxide is added in an amount of 0.5-20% by weight, based on the liquid lower aluminum alkoxide. Then the solution is placed at a temperature of 20-85℃, and it will completely solidify within 24 hours. The lower aluminum alkoxide prepared via the present process has a high purity and can completely solidify within 24 hours, which is one seventh to one fifth of the conventional solidification time. The process is highly efficient and clean, and it will reduce the solidification time without reducing the purity and quality of the lower aluminum alkoxide.
