Is there an established procedure for titanium tetrachloride titration?
$\ce{TiCl4}$ is amenable to distillation if done carefully so as to exclude moisture. That doesn't mean it isn't a pain, however. 

We do a lot of chemistry using $\ce{TiCl4}$ and other Ti Lewis acids (including some Ti aldol reactions on v. small scale), so end up having to distill it quite often (roughly once a quarter). Once distilled, it lasts in the fridge until it runs out so long as the flask is well sealed and everyone remembers to flush with argon before they're finished using it. 

I'll quote from Purification of Laboratory chemicals for general information, but also note that we don't follow this procedure. (Mercury makes me uncomfortable)

In practice, we simply distill the $\ce{TiCl4}$ under reduced pressure (high vacuum pump), discarding the first few mL as would be common procedure. This usually yields $\ce{TiCl4}$ that is clear in colour and sufficiently pure for our chemistry. If some colour remains, a second distillation from copper turnings is occasionally done, but this is rarely needed. 

The key bit of information is to make sure that you quench all of the glassware and tubing used with a weak base (sodium hydrogen carbonate is sufficient), and to ensure that the pump exhausts into a good fume cupboard incase any fumes do escape. All of the glassware used should also be heavily dried prior to use.
