Reaction Conditions:
with dihydrogen hexachloroplatinate;10H-phenothiazine at 85; under 1125.11 - 3000.3 Torr; for 4 h;Catalytic behavior;Autoclave;Inert atmosphere;Pressure;
Steps:
4 Embodiment 4
To a 2L autoclave equipped with a plunger metering pump inlet,Add 476.6g (3.90mol) of TMS,5.8 g of phenothiazine and 2.9 ml of Speier catalyst,Close the reaction vessel and start stirring.After replacing with nitrogen, it is heated to 85 ° C, and the kettle pressure is 0.15 MPa.365.8 g (2.90 mol) of AMA was slowly injected into the autoclave via a plunger metering pump to control the amount of injection.The kettle pressure is 0.2-0.4 MPa, and the injection time is about 2 hours.After the injection, the reaction was stirred at 85 ± 5 ° C for 2 hours.The temperature was lowered to room temperature, and after the pressure was released, the pale yellow reaction liquid was poured out.The reaction solution is subjected to fractional distillation under reduced pressure through a packed fractionation column (Φ2.5*100 cm, glass spring packing).Recover excess 110g of TMS,Collecting 679g of 120-125 ° C / 670-780Pa fraction,The yield was 94.30%, the purity was 99.78% (GC), and the high boiler was 30.1 g.
