Terminal hydrogen-based polysiloxane production system

The utility model discloses a terminal hydrogen-based polysiloxane production system which comprises a raw material pre-treatment device, a copolymerization kettle, a coarse product post-treatment device and a finished product storage tank, wherein the raw material pre-treatment device is used for dehydrating and dechlorinating a raw material which is methyl cyclosiloxane; in the copolymerization kettle, the raw material reacts to obtain a coarse product; the coarse product post-treatment device is used for removing impurities out of the coarse product, and the finished product storage tan is used for collecting a finished product terminal hydrogen-based polysiloxane. According to the production system disclosed by the utility model, terminal hydrogen-based polysiloxane is produced from methyl cyclosiloxane and tetramethyl dihydrodisiloxane without adding organic solvents, and the reaction conditions are mild. Furthermore, no harmful gases are discharged, and therefore the system is safe and environment-frien
