Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical preparation equipment, in particular to a catalyst preparation equipment for quantitative addition. Background Art

[0002] Alkyl zinc reagents are an important class of organic synthesis reagents with a wide range of applications, including medicinal chemistry, materials science, and organic chemistry. In the pharmaceutical field, alkyl zinc reagents are widely used in the synthesis and modification of drugs due to their unique reactivity and selectivity. However, in the preparation and application of alkyl zinc reagents, the selection and configuration of catalysts are one of the key factors restricting their performance.

[0003] In the traditional preparation process of alkyl zinc reagents, the selection and configuration of catalysts often rely on the experimenter's experience and intuition, lacking precise control and quantitative analysis. This traditional preparation method is not only inefficient, but also difficult to ensure the consistency and stability of product quality.

[0004] Currently, to achieve quantitative feeding, most catalyst dispensing equipment is equipped with an electronic scale to weigh the raw materials. However, after the electronic scale is used to complete the weighing operation, these dispensing equipment still requires manual removal of the weighed raw materials and then manually adding them to the corresponding dispensing device. This operation is relatively cumbersome, affects the efficiency of feeding, and brings inconvenience to the user. In view of this, we have proposed a catalyst dispensing equipment with quantitative feeding. Utility Model Content
