Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of 3,5-dimethylbenzoic acid processing equipment, specifically a centrifugal separator for 3,5-dimethylbenzoic acid. Background Technology
[0002] 3,5-Dimethylbenzoic acid (also known as 2,4-dimethylbenzoic acid) is an organic acid with important chemical properties, widely used in pharmaceuticals, cosmetics, and synthetic materials. However, its production process usually requires solid-liquid separation to remove unreacted solid raw materials or byproducts. When using centrifuges for solid-liquid separation, the separation effect is often unsatisfactory due to the characteristics of 3,5-dimethylbenzoic acid.
[0003] First, 3,5-dimethylbenzoic acid has high solubility, especially in some solvents. This results in a relatively uniform distribution in solution, with solid particles often being small and evenly dispersed, making it difficult to be effectively precipitated by centrifugation. For small-sized solid particles, the separation effect produced by centrifugation is usually poor, significantly impacting separation efficiency. Second, the benzene ring structure and methyl groups present in the 3,5-dimethylbenzoic acid molecule give it high lipophilicity in certain solvent systems. This causes some solid particles to adhere to the solvent or the surface of other solid particles, further reducing the effectiveness of centrifugal separation. No solutions have yet been proposed to address these technical problems. Utility Model Content

The purpose of this invention is to achieve efficient removal of insoluble impurities from solutions, improve product purity, and through centrifugal separation, solid particles can be rapidly precipitated and separated, thereby reducing cross-contamination between soluble substances and impurities, improving separation efficiency, saving time and resources, and effectively enhancing the economics of production.
