Abstract

The invention discloses a multi-stage feeding ultra-gravity liquid-liquid reactor device, which comprises a rotor, a casing upper cover, a liquid distributor and a casing; the lower end of the casing is provided with a liquid outlet; it is characterized in that: the liquid The distributor includes an inner liquid distributor and an outer liquid distributor; the rotor is provided with concentric packing rings with different diameters and built into the housing; there is a gap between the packing ring and the upper cover of the housing, and The space between the concentric packing rings of different diameters and the upper cover of the shell is connected; the inner liquid distributor extends to the middle of the rotor; the outer liquid distributor respectively extends into the space between the concentric packing rings. The device of the present invention does not need a sealing device between the top of the packing ring and the upper cover of the housing; the liquid distributor of the device can realize multi-stage feeding inside the rotor; it can realize the rapid and uniform molecular scale mixing required for parallel reactions and serial reactions , so that the reaction selectivity can be significantly improved, and it has the outstanding advantages of less by-products and high product yield.

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...
