TANTALUM(V) CHLORIDE Usage And Synthesis
Physical Properties Yellow monoclinic crystals; hygroscopic; critical temperature 494°C; critical volume 402 cm3/mol; can be sublimed without decomposition in chlorine atmosphere; reacts with water; soluble in ethanol, ether and carbon tetrachloride.
Preparation Tantalum pentachloride is prepared by heating tantalum metal with excess chlorine:
2Ta + 5Cl2 → 2TaCl5
Reactions Tantalum pentachloride is hydrolyzed by water to form hydrous tantalum pentoxide, Ta2O5•nH2O and hydrochloric acid:
2TaCl5 + 5H2O → Ta2O5 + 10HCl
Reaction with hydrofluoric acid yields tantalum pentafluoride:
TaCl5 + 5HF → TaF5 + 5HCl
Tantalum pentachloride forms adducts with donor solvent molecules. Also, it forms several complexes and organometallic derivatives.
Reactions with alcohols in the presence of an amine forms dinuclear alkoxides. Thus, with ethanol in the presence of diethylamine, the dinuclear tantalum ethoxide, Ta2(OC2H5)10, is obtained.
Reaction with dimethylzinc forms dichlorotrimethyl tantalum, in which three chlorine atoms are substituted with methyl groups:
2TaCl5 + 3Zn(CH3)2 → 2(CH3)3TaCl2 + 3ZnCl2
Reaction with cyclopentadienyl sodium yields bis(cyclopentadienyl) tantalum trichloride:
TaCl5 + 2C5H5 Na → (C5H5)2TaCl3 + 2NaCl
Chemical Properties Pale-yellow, crystalline powder; highly reactive. Decomposed by moist air. Soluble in alcohol and potassium hydroxide solution. Keep well stoppered.
Uses Chlorination of organic substances, intermediate, production of pure metal.
Safety Profile Poison by intraperitoneal route. Moderately toxic by ingestion. When heated to decomposition it emits toxic fumes of Cl-.
Purification Methods Purify it by sublimation in a stream of Cl2. It forms colourless needles when pure (yellow when contaminated with even less than 1% of NbCl5). It is sensitive to H2O; even in conc HCl it decomposes to tantalic acid. It is soluble in EtOH.
