摘要：

The numerical simulation results of Fluent software showed that the umbrella-shaped microchannel structure had higher mixing efficiency than the U-shaped linear microchannel structure, but this structure also had flow dead zones. Combined with the optimization direction, a diamond-shaped microchannel structure with smaller pressure drop and better mixing efficiency was proposed, which was more suitable for liquid-liquid heterogeneous reaction. Meanwhile, three different microchannel structure reactors, which were described above, and conventional reactor were used to carry out the comparative evaluation synthesis experiment of tetradecyl acrylate (TA). The analysis and characterization of FTIR and NMR for reaction products had demonstrated the formation of TA. In the conventional reactor, the yield TA was only 82% and the residence time was up to 300minutes. The yields of TA in the microreactors was more than 90% and the residence time was less than 3.5minutes. The yields of TA in the diamond-shaped microreactor was higher than that in the U-shaped linear and umbrella-shaped microreactor, which was up to 97%, indicating that the diamond-shaped microchannel structure was more conducive to the full mixing reaction. It was consistent with the numerical simulation results of the diamond-shaped microchannel structure, verifying the reliability of numerical simulation results. © 2021, Chemical Industry Press Co., Ltd.
