YieldReaction ConditionsOperation in experiment
54% With trifluorormethanesulfonic acid; acetic acid; at 70℃; for 1.5h; Embodiment 2 (0021) A preparation method of (CH3)2 (CH2?CH)SiO(C6H5)(CH3)SiOSi(CH?CH2)(CH3)2; Methylphenyldimethoxysilane (18.20 g), trifluoromethanesulfonic acid (0.10 g), 1,3-divinyl-1,1,3,3-tetramethyldisiloxane (18.64 g) and acetic acid (15.13 g) are added into a four-neck round bottom flask, heated to 70° C. and reacted for 30 min, and then acetic anhydride (5.10 g) is added and continuously reacted for 1 h at the temperature of 70° 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 115-120° C./5 mmHg is collected, wherein the yield is 54.0percent, and the purity is 96percent.
