Effect of the extent of the hydrolysis of tetrabutoxytitanium on catalysis efficiency in the esterification reaction

A study was carried out on the products of the hydrolysis of tetrabutoxytitanium and their catalytic activity in the esterification reaction. A maximum is observed in the dependence of the reaction rate constant on the extent of the hydrolysis of tetrabutoxytitanium. The maximum effective esterification rate constant corresponds to 60% hydrolysis of tetrabutoxytitanium. The hydrolysis products in this case have largely linear structure. The relationship between the catalytic activity of linear polytitanates and their stability in the reaction medium is discussed.
