実験手順

A mixture containing 747 g. (3 moles) of finely divided dibutyltin oxide and 147.5 g. (1.5 mole) of maleic anhydride was blended in a tumbling type mixing apparatus available as Twin-Shell Dry Blender Model 182181 from Paterson-Kelley Co. Inc. The mixing chamber was maintained at ambient temperature for one hour, at which time the walls of the mixing chamber were heated. At the end of one hour the temperature of the material in the chamber was 54° C. Differential thermal analysis of the material indicated that substantially all of it had reacted to form non-stoichiometric dibutyltin maleate. No significant change in the analysis was observed during three additional hours of heating.
