Talking about titanium halides, i have been wanting to prepare some TiCl3.6H2O. How oxidation sensitive is this? I was thinking of dissolving some
(1g) titanium powder in hot conc. HCl, followed by evaporation. I read somewhere that at some point one must saturated the solution with HCl gas, and
then cool, wich will result in the desired compound crystallising as purple crystals. 3 questions though, for anyone having experience with it's
preparation:
To what volume should the solution be evaporated before being saturated with HCl-gas (ml solution per gram of Ti).
How oxidation sensitive is this compound. Do I have to work under inert gas constantly or is it not that oxidation sensitive?
Can I also extract the chloride with a solvent, such as ether, followed by easy evaporation (maybe addition of a little ethanol to also easily
evaporate the water in the ether as the azeotrope). |
