Purification Methods

A possible impurity is tributylchlorostannane — test for Cl as Cl ion after hydrolysing. Dissolve it in *C6H6 (or toluene), shake this with dilute aqueous NaOH, dry (CaCl2), filter, evaporate and distil the residue in a vacuum [Jones et al. J Chem Soc 1446 1947, Bristow Aldrichimica Acta 17 75 1984, Yamamoto Aldrichimica Acta 20 45 1987]. [Beilstein 4 IV 4317.]
