Description
Tetrabutyl titanate, also known as Titanium(IV) butoxide, is an organometallic compound with the chemical formula Ti(OC4H9)4. It is a colorless liquid at room temperature and is soluble in organic solvents. It is used as a catalyst, intermediate, and additive in various applications.
Uses
Used in Chemical Synthesis:
Tetrabutyl titanate is used as a catalyst and intermediate in ester exchange reactions, facilitating the formation of esters from alcohols and carboxylic acids.
Used in Paints and Coatings Industry:
Tetrabutyl titanate is used as a cross-linking agent and condensation catalyst in the production of heat-resistant paints that can withstand temperatures up to 500°C. It also improves the adhesion of paints, rubber, and plastics to metal surfaces, enhancing the durability and performance of the coatings.
Used in Nanotechnology:
Tetrabutyl titanate is used in the preparation of nanosized titania powders in the anatase form and ferroelectric bismuth titanate thin films. It is also involved in the preparation of nanocrystalline titanium dioxide powders at room temperature, which have various applications in the field of nanotechnology.
Used in Solar Energy Applications:
Tetrabutyl titanate is a sourcing material for the preparation of titanium oxide (TiO2), which can be used in dye-sensitized solar cells (DSSCs). These solar cells have the potential to convert sunlight into electricity with high efficiency and are considered a promising alternative to traditional silicon-based solar cells.
Used in Photocatalytic and Self-Cleaning Coatings:
Titanium dioxide, prepared from tetrabutyl titanate, is used in photocatalytic and self-cleaning coatings. These coatings have the ability to break down organic pollutants and dirt under sunlight, making them ideal for use in architectural and automotive applications.

Flammability and Explosibility
Flammable
Safety Profile
Suspected carcinogen.
A poison by intravenous route. Moderately
toxic by ingestion. See n-BUTYL
ALCOHOL and TITANIUM
COMPOUNDS. Flammable when exposed
to heat or flame. To fight fire, use water,
spray, foam, dry chemical. Incompatible
with oxidizing materials. When heated to
decomposition it emits acrid and irritating
fumes.
Purification Methods
Dissolve it in *C6H6, filter if solid is present, evaporate and vacuum fractionate through a Widmer 24inch column (p 11). The ester hydrolyses when exposed to air to give hydrated ortho-titanic acid. The titanium content can be determined thus: weigh a sample (ca 0.25g) into a weighed crucible and cover it with 10mL of H2O and a few drops of conc HNO3. Heat (hot plate) carefully till most of the H2O has evaporated. Cool and add more H2O (10mL) and conc HNO3 (2mL), and evaporate carefully (no spillage) to dryness and ignite the residue at 600-650o/1hour. Weigh the residual TiO2. [Bradley et al.

Check Digit Verification of cas no
The CAS Registry Mumber 5593-70-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,9 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5593-70:
(6*5)+(5*5)+(4*9)+(3*3)+(2*7)+(1*0)=114
114 % 10 = 4
So 5593-70-4 is a valid CAS Registry Number.

SYNTHESIS OF ALKYL ORTHOTITANATES IN TWO-PHASE SYSTEMS.
Yatluk,Suvorov
, p. 1678 - 1680 (2008/10/08)
The authors have carried out an investigation aimed at development of more convenient methods for production of alkyl orthotitanates in two-phase systems. In studies of the reaction of titanium tetrachloride with alcohols in presence of organic amides the authors found that the latter are not indifferent solvents but take part in the reaction. The interaction of titanium tetrachloride, an organic amide, and an alcohol in 1:4:(8-9. 6) molar ratio results in splitting of the amide and formation of the corresponding amine hydrochloride and ester.
