YieldReaction ConditionsOperation in experiment
51.2% With trifluorormethanesulfonic acid; acetic anhydride; acetic acid; at 65℃; for 2.5h; Embodiment 1 (0019) A preparation method of (CH3)2(CH2?CH)SiO(C6H5)2SiOSi(CH?CH2)(CH3)2; (0020) Diphenyldimethoxysilane (61.09 g), trifluoromethanesulfonic acid (0.20 g), 1,3-divinyl-1,1,3,3-tetramethyldisiloxane (46.60 g) and acetic acid (37.81 g) are added into a four-neck round bottom flask, heated to 65 C. and reacted for 30 min, and then acetic anhydride (12.76 g) 6g) is added and continuously reacted for 2 h at the temperature of 65 C. The temperature is reduced to room temperature after the end of reaction, toluene is added for dilution, and washing with deionized water is performed to neutral. A toluene layer is collected, and anhydrous calcium chloride is added for drying. A drying agent is filtered out, and toluene is removed by concentrating filtrate. Reduced pressure distillation is performed on concentrate, and a fraction of 165-170 C./4 mmHg is collected, wherein the yield is 51.2%, and the purity is 99%. The structure of the product is proved to be delta (ppm): 0.156 (12H, -CH3), 5.71-5.938 (4H, ?CH2), 6.09-6.149 (2H, -CH?), 7.318-7.584 (10H, -C6H5) through a spectrogram of 1H NMR (CDCl3).
