Properties of Tetraisopropyl Titanate

Tetraisopropyl titanate (Tetra(isopropyl) orthotitanate), the chemical formula Ti(OCH(CH) ₂), is a colorless or light yellow liquid with high volatility. It is easily hydrolyzed in air to produce isopropyl titanate and propanol. In the molecular structure of tetraisopropyl titanate, the titanium atom forms coordinate bonds with four isopropoxy groups, showing the properties of typical metal organic compounds. It has strong oxidation and high chemical reactivity, especially for water and moisture in the air is very sensitive.

Use of tetraisopropyl titanate

Tetraisopropyl titanate is widely used in industry and scientific research. It is a key intermediate for the preparation of titanates and titanium compounds, and is commonly used in the production of titanium dioxide, titanium oxides and strontium titanate. It is used as a catalyst and crosslinking agent in the paint and coating industry, which can improve the heat resistance and corrosion resistance of the coating. Tetraisopropyl titanate is also an important raw material for the manufacture of optical glass and ceramics, which can improve the optical properties and mechanical strength of the material. In organic synthesis, it can be used as an efficient catalyst for various esterification, condensation and polymerization reactions.

Upstream raw material of tetraisopropyl titanate

The production of tetraisopropyl titanate requires several key upstream raw materials. The source of titanium is usually titanium tetrachloride (TiCl6), an important titanium compound. Titanium tetrachloride reacts with isopropanol at elevated temperatures to produce tetraisopropyl titanate and hydrogen chloride (HCl). Isopropanol is another key raw material, which needs to be of high purity to ensure the smooth progress of the reaction. The production process also requires proper control of catalysts and reaction conditions to improve yield and product quality.

Tetraisopropyl titanate downstream products

Tetraisopropyl titanate is a precursor for many high value-added products. Titanium dioxide is one of the most important downstream products, widely used in coatings, plastics, paper and cosmetics industries, as a white pigment and UV absorber. Titanates such as strontium titanate and barium titanate are important electronic materials used in the manufacture of capacitors, piezoelectric components, and ceramic dielectrics. Titanium oxides are used as catalysts, photocatalysts and antibacterial materials, and are used in environmental protection and new energy fields. Tetraisopropyl titanate is also used to produce functional coatings and high-performance composite materials to improve the performance and life of materials.

Tetraisopropyl Titanate Storage Method

Due to the very active chemical nature of tetraisopropyl titanate, special care is required during storage. The storage environment should be dry, cool and ventilated, avoid direct sunlight and high temperature. Containers should be well sealed, usually glass bottles or metal containers protected with an inert gas (such as nitrogen) to prevent hydrolysis by reaction with moisture in the air. Contact with strong acids, strong bases and oxidants should also be avoided during storage to prevent dangerous reactions. When using and handling tetraisopropyl titanate, wear appropriate personal protective equipment, such as gloves, protective glasses and protective clothing to ensure safe operation.

Market Prospects and Trends

As an important titanium compound and intermediate, the market demand for tetraisopropyl titanate is stable and showing a growing trend. With the development of high-performance materials and emerging technologies, the demand for tetraisopropyl titanate is expected to increase further. For example, the growing demand for photocatalysts and energy storage materials in the new energy sector has driven the demand for high-purity tetraisopropyl titanate. The development of environmentally friendly coatings and functional coatings market also provides new application space for tetraisopropyl titanate. In the future, with the technological progress and the optimization of production process, the production cost of tetraisopropyl titanate is expected to be reduced, and the market competitiveness will be further enhanced.
