Method for preparing epoxidized trans-1, 4-polyisoprene by using micro-reaction device

The invention discloses a method for preparing epoxidized trans-1, 4-polyisoprene by using a micro-reaction device, which comprises the following steps: (1) dissolving trans-1, 4-polyisoprene TPI by using an organic solvent to obtain a homogeneous solution A; (2) mixing hydrogen peroxide and a formic acid solution in proportion to obtain a peroxyformic acid solution B; (3) and (3) simultaneously pumping the solution A and the solution B obtained in the steps (1) and (2) into a microreactor of a micro-reaction device, wherein a catalyst is immobilized in the microreactor, reacting, and collecting effluent liquid to obtain the catalyst. Compared with the prior art, the invention has the following advantages: (1) the method has the advantages of quick reaction, low yield, low cost, high safety, good operability, small reaction volume, short time and less corrosion to equipment; (2) the production method has simple process, can realize continuous production, and has higher operation safety and controllability.
