Procedure

A 500 ml four-necked flask was charged with 95.0 g of n-butyl tri-n-dodecyltin, 36.4 g of tin tetrachloride and 150 ml of n-heptane, and they were reacted at 40° to 50° C. for 1 hour. After the reaction, the reaction mixture was washed three times with 100 ml of 10% aqueous solution of hydrochloric acid to remove mono-n-butyltin trichloride. The organic layer was dried with anhydrous magnesium sulfate, and concentrated to afford 89.3 g of tri-n-dodecyltin chloride having a purity of 97.2% as an oily substance (m.p. 30° to 32° C.).
