PROCESS FOR THE PREPARATION AND SOLIDIFICATION OF LOWER ALUMINUM ALKOXIDE

摘要

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 40-85C, 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 20-85C, 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.
