反応手順
The same apparatus as used in Example 1 was employed. To the flask were continuously fed 450 g of 30% aqueous sodium hydroxide solution and 300 g of tri-n-butyltin bromide containing 3.5% di-n-butyltin dibromide, with stirring and heating at 60° C., to perform hydrolysis for 60 minutes. To the resulting reaction mixture was added 260 g of water for specific gravity adjustment. The same precipitation as in Example 1 took place, and the reaction mixture split into three distinct phases. The specific gravity of the aqueous phase was measured and was found to be 1.25. Thereafter, the upper phase was treated in the same manner as in Example 1 to give 224.4 g (92.8% yield) of bis(tri-n-butyltin) oxide. Analysis revealed that the product was of high quality, its purity being 98.3% and the content of di-n-butyltin oxide dissolved therein being 300 ppm.
