Claim 1:
2. The method of claim 1, wherein the steps (1) and (2) comprise the following steps of:
(1) simultaneously pumping a mixed solution prepared by dissolving the epoxidized vegetable oil and the basic catalyst in the inert solvent and a mixed solution prepared by dissolving the benzoylformic acid in the inert solvent into the first microchannel reactor in the microchannel reaction device to subject to a ring-opening reaction to obtain a reaction solution containing the vegetable oil polyol;
(2) pumping a mixed solution prepared by dissolving the reaction solution containing the vegetable oil polyol obtained in the step (1) and the propylene oxide in the inert solvent into the second microchannel reactor of the microchannel reaction device to subject to an addition polymerization reaction to obtain the vegetable oil polyol for the flexible polyurethane foam.
