Butyl titanate is an important raw material for chemical production, which has unique properties and a wide range of uses. This article will detail the properties, synthesis methods, analysis methods and applications in various fields of butyl titanate.
1. the properties of butyl titanate
butyl titanate is a colorless to pale yellow transparent liquid with a special pungent odor. Its molecular formula is Ti(OC4H9)4 and its molecular weight is 284.22. Butyl titanate is insoluble in water, but soluble in most organic solvents, such as alcohol, ether, benzene, etc. It is sensitive to air and is easily hydrolyzed to produce titanic acid and butanol.
butyl titanate has good chemical stability and thermal stability, and can decompose at high temperature to form titanium oxide. In addition, it also has excellent ultraviolet absorption properties and can be added to plastics, coatings and other products as an ultraviolet absorber. The synthesis method of
2. butyl titanate
There are two main synthesis methods of
butyl titanate: sulfuric acid method and ester exchange method. The sulfuric acid method is to react titanium tetrachloride with concentrated sulfuric acid to generate titanium oxysulfate, and then react with n-butanol to obtain butyl titanate. The transesterification law is to react titanium tetrachloride with n-butanol to generate tetrabutyl titanate, and then react with water to obtain butyl titanate by hydrolysis.
3. analysis method of butyl titanate
analysis method of butyl titanate mainly gas chromatography, spectrophotometry and titration. Gas chromatography can accurately determine the content of butyl titanate, spectrophotometry can be used to determine the content of impurities in butyl titanate, and titration method can be used to determine the acidity and alkalinity of butyl titanate.
4. the use of butyl titanate
1. Plastic additives: butyl titanate can be used as plastic additives to improve the heat resistance, weather resistance and mechanical properties of plastics. It can also act as an ultraviolet absorber to prevent plastic aging.
2. Coating additive: butyl titanate can be used as a coating additive to improve the weather resistance, UV resistance and decoration of the coating. It can increase the hardness and gloss of the coating and improve the corrosion resistance of the coating.
3. Ceramic additives: Butyl titanate can be used as ceramic additives to improve the density, toughness and thermal stability of ceramics. It can be used to prepare high-performance ceramic materials.
4. Catalyst: Butyl titanate can be used as a catalyst for organic synthesis reactions. It can promote the reaction and improve the selectivity of the product.
In short, butyl titanate as an important chemical production raw materials, in various fields have a wide range of applications. With the continuous development of science and technology, its application field will continue to expand.
