Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, in particular to a chiral reagent recovery and processing device. Background Art

[0002] Catalysts can induce changes in chemical reactions, making them faster or slower or allowing them to proceed at lower temperatures. The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is like that between a lock and a key, with a high degree of selectivity (or specificity). Chiral catalysts are catalysts containing chiral C atoms, which play a vital role in some synthetic reactions. Chiral catalysts are commonly used substances in the field of chemical synthesis. Therefore, in order to make the catalyst reusable, the catalyst is generally activated.

[0003] Activation is to convert the catalyst into the active phase required for the catalytic reaction after it has been treated by a certain method. When they are calcined or further reduced, oxidized, sulfurized, etc., so that they have certain properties and numbers of active centers, they are converted into the active state of the catalyst. The activation process of the catalyst is sometimes carried out in a catalyst production plant. The existing catalyst activation device has the following problems: 1. When the catalyst is dried, the quality of the catalyst will be uneven due to uneven heating, affecting its use. 2. The catalyst activation device is an activation furnace. This type of activation furnace will produce smoke during use, which is easy to pollute the environment. Utility Model Content

[0004] The utility model provides a chiral reagent recovery and processing device. The utility model enables the activation kettle to be heated evenly and no smoke is generated.

[0006] The invention discloses a chiral reagent recovery and processing device, comprising an activation kettle, a chiral reagent crude product storage container, a jacket, a steam inlet valve assembly, a steam outlet valve assembly, a delivery pump, a solvent storage tank, a condenser and a receiving tank. The activation kettle is provided with a first material input port, a second material input port and a vaporized product output port. The output end of the chiral reagent crude product storage container is connected with the first material input port. After the jacket is matched with the activation kettle, a spacing space is formed between the jacket and the activation kettle. The jacket is provided with an input port and an output port. The steam inlet valve assembly is connected with the input port, the steam outlet valve assembly is connected with the output port, the input end of the delivery pump is connected with the solvent storage tank, the output end of the delivery pump is connected with the second material input port, the input end of the condenser is connected with the vaporized product output port on the activation kettle, the output end of the condenser is connected with the input end of the receiving tank, and the output end of the receiving tank is connected with the solvent storage tank.

[0011] The utility model uses steam to heat the activation kettle when activating the chiral reagent, which not only makes the activation kettle evenly heated, but also does not generate smoke, thus avoiding environmental pollution. The solvent used for activation is delivered by a delivery pump, so that the amount of the solvent can be easily controlled. The solvent used for the activation reaction is formed into a vapor by distillation, and the vapor enters the condenser to form a liquid, and is recovered into the solvent storage tank through a receiving tank. Therefore, the steam not only activates the chiral catalyst, but also recovers the solvent used for the activation reaction. BRIEF DESCRIPTION OF THE DRAWINGS
