실험 절차

A mixture of 2.28 kg of maleic anhydride and 5.97 kg of dibutyltin oxide is continuously added to a screw drier whose heat exchange areas consist of two heating and one cooling zone. Behind each heating zone, a suction device is present for removing any water of reaction which may be formed. The reaction mixture passes through both heating zones at an average residence time of 7.5 minutes, the temperature of the first heating zone being 68° C. and that of the second one being 63° C., and is then cooled to 25°-30° C. At the exit of the screw drier, dibutyltin maleate (compound 3), is obtained as a white free-flowing powder.
