[0075] Example 2 Preparation Example
[0076] use figure 1 The device shown continuously prepares organosilicon monomers containing special groups. The reactor used is a stirred three-phase fluidized bed reactor made of stainless steel enamel reactor with a diameter of 23cm and a length of 125cm; the lower insulation layer The length is 85cm, the overflow port is 100cm away from the bottom of the reactor, the effective reaction diameter of the reactor is 20cm, and the effective reaction volume is 31.4L.
[0077] A) drying equipment
[0078] The reactor and all piping are to be purged with dry air until dry.
[0079] B) Loading magnesium chips
[0080] Under the protection of inert gas, magnesium chips are fed into the stirred three-phase fluidized bed reactor through the magnesium feeding bin until the 5~50cm above the stirring paddle is buried.
[0081] C) Initiate a reaction
[0082]Heating the reactor means that when the temperature in the reactor reaches 65 degrees Ce...
