YieldReaction ConditionsOperation in experiment
88.97% Add 200 g of <strong>[6843-66-9]<strong>[6843-66-9]diphenyldimethoxysilan</strong>e</strong> to a 2 L four-necked flask equipped with a thermometer, a constant pressure dropping funnel, a stirrer, and a condenser. Then, add 20 g of concentrated sulfuric acid having a mass concentration of 98%, and mix for 10 minutes. The constant pressure dropping funnel was slowly added dropwise 400 g of tetramethyldihydrodisiloxane, and the addition time was 4 h. After the completion of the dropwise addition, stirring was continued for 24 hours, 80 g of sodium carbonate was added for neutralization for 2 hours, vacuum filtration was carried out, and the filtrate was distilled under reduced pressure. A fraction of 130 to 131 C / 2.5 mmHg was taken to obtain a colorless transparent liquid, which was tetramethyldihydrodiphenyltrisiloxane. The weight was 242 g, the yield was 88.97%, and the chromatographic detection content was 99.5%.
