Organic solvent extraction system for purifying organic acids

Overview

The organic solvent extraction system developed by Shandong Jinlin Technology Development Ltd offers a significant advancement in the separation and purification of organic acids. By carefully selecting and optimizing the extractant and diluent, this system improves the extraction efficiency and purity of target organic acids. This technology is particularly effective in isolating organic acids such as lactic acid, citric acid, and succinic acid, among others, from fermentation broths by minimizing impurities like sugars and proteins.

Technical specifications

Key features:

• Utilizes specific extractants selected based on polarity, molecular structure, and acid-base properties to enhance affinity for target compounds.
• Optimization of conditions including temperature, pH, and stirring rate increases extraction efficiency.
• Diluents are chosen to prevent impurities from entering the organic phase, thus improving the separation coefficient.
• Validated for industrial production of lactic acid and pilot-scale for citric, succinic, itaconic, and aconitic acids.

Technology readiness level

This technology is at Technology Readiness Level 5, with lactic acid already implemented in industrial production and other acids validated at pilot scale. The system is ready for further industrial application and optimization, and the organization is seeking partnerships for joint development and licensing.
