実験手順

The foregoing procedure was repeated using 124.35 g. (0.5 mole) of di-n-butyltin oxide and 24.5 g. (0.25 mole) of maleic anhydride with 100 cc. water as the reaction medium. In this instance the water and maleic anhydride were combined and heated to 50° C. to dissolve the anhydride. The solution was then cooled to 30° C., at which time the di-n-butyltin oxide was added. The resultant mixture was then heated to the boiling point (98° C.) and maintained at that temperature for 2 hours with stirring. The liquid phase was decanted and the solid washed with 200 cc. of water. The dried solid weighed 148.85 g. (98.5% of theoretical yield) and was found to contain 33.3% by weight of tin. The theoretical tin content for the reaction product of di-n-butyltin oxide and maleic anhydride in a 2:1 molar ratio, respectively is 34.0% by weight.
