摘要
Disclosed is a new method for the preparation of metallic acid esters of titanium, zirconium or hafnium wherein a halide of the metal reacts with an organosilane ester, resulting in the formation of partial esters of the metallic acids. The degree of esterification of the metallic acid ester can be controlled based on the organosilane ester and it is possible to obtain complete esterification of the metal halides. The metallic acid partial esters prepared by the method are very pure, and can be separated selectively from the mixture in a simple manner. The metallic acid alkyl esters obtained can very easily be further esterified to the metallic acid tetraalkyl esters with the formation of very pure tetraalkyl esters.
