Tantalum chloride Specification

Tantalum chloride with cas registry number of 7721-01-9 is white to pale yellow crystals, also known as Tantalum pentachloride ; Tantalum chloride (TaCl₅) ; Tantalumchlorideanhydrous . It is less soluble in cyclohexane and carbon tetrachloride than in the aromatic hydrocarbons. The solubility increases to a slightly for the following series: benzene< toluene< m-xylene< mesitylene, as reflected in the deepening of colour of the solutions from pale yellow to orange. Tantalum chloride is strongly electrophillic as a Friedel-Crafts type catalyst and can form adducts with a variety of ligands such as [TaCl₅(OPCl₃)]. It can product many chemicals in chloride displacement reactions, and ammonolysis and amide-forming reactions such as TaCl₅ + 5LiOMe → Ta(OMe)₄Cl + 4LiCl.
