실험 절차

3.0 kg chloroplatinic acid crystals (40% platinum content) and 15.0 kg isopropanol were placed in a 50-L reactor, and 6.0 kg sodium bicarbonate and 6.0 kg 1,3-divinyltetramethyldisiloxane were then added while stirring. The resulting suspension was heated while stirring. After reacting for 30 minutes at 65 to 75° C., the reaction mass was cooled and the solids were filtered off to give 22.0 kg of an isopropanol solution of platinum-divinyltetramethyldisiloxane complex catalyst. The platinum content was 4.1% as measured by x-ray fluorescence analysis, and the 1,3-divinyltetramethyldisiloxane content as measured by gas chromatography was 9.4%.
