A glass reactor was charged with 91.1 g (0.3 mole) dibutyltin dichloride, 200 cc n-butanol, 50 cc water and 27.3 g (0.15 mole) dibasic sodium phosphate dihydrate. The resultant mixture was heated under a nitrogen atmosphere and the water removed by azeotropic distillation until the vapor temperature reached 117° C. The reaction mixture was then filtered and the liquid phase was concentrated under reduced pressure. The liquid residue solidified upon standing and weighed 83 g. The product was found to contain 34.60% tin, 11.18% chlorine and 4.42% phosphorus. The calculated values for these elements in the expected product are 37.53% tin, 11.21% chlorine and 4.90% phosphorus.
