Description

Technical field [0001] The invention relates to a multi-stage feed supergravity liquid-liquid reactor device and its application. The device can be applied to rapid parallel, series and other liquid-liquid reaction systems, and belongs to the field of supergravity technology. Background technique [0002] A chemical reaction is a process of rearranging atoms. Even for a single reactant, because the rearrangement of atoms is different, the resulting products are also diverse. Parallel reaction and series reaction are two common reaction systems. Generally speaking, the number of reactive species is generally greater than or equal to 2. For parallel reactions, the reactants can carry out two or more different reactions in parallel at the same time, resulting in different products. The reaction that can produce the desired product is called the main reaction, and the rest are called side reactions. The reaction equation can be expressed as follows (R represents the desired produ...
