Description
Titanium tetrachloride (CAS 7550-45-0, EC 231-441-9, formula Cl4Ti) is an inorganic acid also known as titanic chloride or TC 36. It carries no assigned E-code. It is registered under REACH and handled as a corrosive, moisture-sensitive liquid requiring controlled storage conditions.
In textile and leather processing, titanium tetrachloride acts as a mordant and surface-modification agent by hydrolyzing on fiber surfaces to deposit titanium dioxide, improving dye adhesion and UV resistance. In catalysis, it serves as a precursor or active component in Ziegler-Natta polymerization systems, initiating controlled chain growth in polyolefin production.
Titanium tetrachloride is supplied in technical and high-purity grades to meet the requirements of pharmaceutical, polymer, and personal care applications. It is available in corrosion-resistant containers sized for industrial procurement volumes. Suppliers operating within the EU must comply with REACH registration obligations given its classification as a corrosive and reactive substance.
