[0053]

[0054] In a word, by adopting the continuous reaction equipment provided by the present invention, the purpose of industrial scale-up production can be achieved by enlarging the size of the reactor (mainly referring to the inner diameter). Thereby avoiding problems of distribution and pressure drop caused by parallel microreactors or series reactors. By using a non-pulse feeding system and maintaining a sufficient linear velocity of the feed liquid, the mixing effect caused by the enlargement of the reactor size and the amplification effect caused by the instantaneous feed error can be effectively avoided. Through sufficient pre-cooling and controlling the temperature of the external bath of the reactor, the amplification effect of the heat transfer effect can be effectively reduced.

Abstract

The invention provides continuous reaction equipment and application thereof. The reaction equipment comprises at least two pre-reaction raw material supply units, a first static mixer, at least one final reaction raw material supply unit, a second static mixer, a continuous reaction unit, a plurality of pulse-free liquid displacement units, a plurality of continuous pre-cooling units and a temperature control system, wherein each pre-reaction raw material supply unit is used for supplying one pre-reaction raw material, the first static mixer is used for statically mixing the pre-reaction rawmaterials for reaction to generate an intermediate, each final reaction raw material supply unit is used for supplying one final reaction raw material except the intermediate, the second static mixeris used for statically mixing the intermediate and the final reaction raw material to form a mixed feed liquid, and the continuous reaction unit is used for carrying out continuous reaction on the mixed feed liquid to generate a final product. The continuous reaction equipment disclosed by the invention can be used for realizing amplified production of reaction with extremely short reaction time.

Description

technical field [0001] The present invention relates to the technical field of continuous reaction, in particular, to a continuous reaction device and its application. Background technique [0002] In organic synthesis reactions, there are many reactions, and the raw materials can be directly reacted to form products. Likewise, there are many reactions that go through a "very short-lived intermediate" stage in the reaction process. In the presence of other reactants (these other reactants, we will call them quenching reagents), after these intermediates are formed (pre-reaction), they immediately react with quenching reagents (final reaction) to generate products, thereby avoiding the generation of impurities and side effects product. However, when the quenching reagent is not compatible with the reaction conditions required to generate these intermediates, this reaction strategy is no longer feasible from a traditional batch process chemistry perspective. However, unlike...
