Titanium tetrabutanolate is a chemical compound of titanium from the group of alcoholates .

Extraction and presentation

Titanium tetrabutanolate can be obtained by reacting titanium (IV) chloride with butanol .

properties

Titanium tetrabutanolate is a flammable, moisture-sensitive, colorless to yellowish liquid with an aromatic odor that slowly decomposes in water.

use

Titanium tetrabutoxide is used as esterification - / alcoholysis - catalysts , alkyl - / epoxy - / silicone resin - cross-linking agent , Ziegler catalyst component, high-temperature coating ingredient and glass surface treatment agent used. It is also used for the production of nanoscale titanium dioxide in the anatase form and ferroelectric Bi ₄ Ti ₃ O ₁₂ thin films.
