However, the intermittent reactor has the defects of overlong reaction time, large mass transfer resistance, uneven internal heating and the like, and is characterized in that the pregnant potential safety hazard is more prominent in dangerous processes such as nitration, hydrogenation, oxidation and the like. This is a major problem which has been difficult to solve for a long time, and for this reason, a great deal of theoretical discussion and practical research has been conducted by various scientific research institutions and enterprises at home and abroad for a long time. In addition to some processes which can be used in fixed bed, fluidized bed and plate-type reactors, in recent years, tank-type series, large-caliber tubular static reactors, loop reactors and high-flux-microchannel continuous reactors are gradually introduced by foreign companies, and the transition and development from the traditional batch reaction to the continuous production process gradually progresses.
Among them, the high throughput-microchannel continuous flow reactor by corning corporation has the most remarkable points: reaction liquid with corresponding flow enters the reactor, mixing reaction is carried out in the heart-shaped channel module in the reactor, and the fluid undergoes a turbulent flow careful mixing process, so that the phenomenon of back mixing hardly occurs. The reaction is rapid and thorough, and the solvent can be reduced or even not used, so that the conversion rate, the purity and the yield of the product are greatly improved. Therefore, the principle is more advanced in the chemical reactor at present. However, the complex processing technology results in extremely high price, which limits the application of the method in the field of small-scale tests.
