Abstract
Tetraalkyltin is separated from impure mixtures of tetraalkyltin and trialkyl tin chloride by reacting the mixture with an aqueous solution of an alkali metal hydroxide to convert the trialkyltin chloride into trialkyltin oxide and separating the tetraalkyl tin, preferably by distillation. The trialkyltin oxide remaining as still bottoms may be re-converted by addition of hydrochloric acid to the chloride. Reaction may take place at a temperature of between 75-85 DEG C. A trace of a wetting agent, e.g. decylbenzene sulphonate, may be added to the alkali metal hydroxide. In an example an aqueous solution of sodium hydroxide containing a wetting agent is added to a mixture of tributyltin chloride, tetrabutyltin, dibutyltin dichloride and other impurities at 75-85 DEG C. The organic phase is separated and the tetrabutyltin distilled. Tributyltin oxide remaining is reacted with hydrochloric acid and the tributyltin chloride distilled from the organic phase. Specifications 695,610, 701,714 and 740,274 are referred to.
