実験手順

On the other hand, 38 g of stannous chloride, 26 g of lead acetate and 200 g of water were charged into a 500 ml beaker equipped with a stirrer and the metal salts were dissolved into the water with stirring. This aqueous solution of the metal salts was added to the aforesaid aqueous solution of potassium naphthenate and a double decomposition reaction was then carried out for 1 hour at 30° C. The reaction mixture was dehydrated, dried and then extracted with toluene. The residue was heated under a reduced pressure of 10 mm Hg to distill off the toluene whereby stannous and lead naphthenates were obtained which had a tin content of 13.2% by weight and a lead content of 9.2% by weight.
