摘要：

We successfully developed a new type of micromixer for instant mixing and rapid heating under high pressure and high temperature. The mixer has several distinguished features: the mixing within ten milliseconds, good insulation of heat, and high throughput. We confirmed these features by the examination of mixing experiments. Finally, we tried to produce bohmite nanoparticles by the super critical water reaction at 400 degrees C in 30 MPa, and the fine particles the average diameter of which is ca. 20 nm were obtained. It is expected that the developed micromixer will be applied widely to various reactions that require severe reaction conditions.
