Weak Base Macroporous Anion Exchange Resin for Citric Acid Purification

Weak Base Macroporous Anion Exchange Resin for Citric Acid Purification

This passage describes the application of a specific resin, C330 (701), in purifying citric acid produced through fermentation. Here's a breakdown of the key points:

Citric Acid Production and Challenges:

Citric acid production involves fermentation, which generates impurities like salts and pigments.
Refining is needed to remove these impurities and meet quality standards.
Traditional ion-exchange resins for desalination and decolorization suffer from:
Reduced lifespan due to high osmotic pressure from citric acid.
Increased processing costs due to frequent resin replacement.
C330 (701) Weak Base Macroporous Anion Exchange Resin as a Solution:

This ion exchange resin is specifically designed to address the challenges in citric acid purification.
Key features and benefits:
High volume exchange capacity: Reduces production costs.
Fast exchange rate and high removal precision: Effectively removes chloride, sulfate, and other impurities.
Special white ball process: Enhances mechanical strength to withstand citric acid's osmotic pressure.
Uniform resin channels: Enables easier regeneration and longer service life.
Uniform particle size: Improves hydraulic performance and reduces pressure drop, ideal for large-scale production.

Overall, C330 (701) resin offers an efficient and cost-effective solution for desalination and decolorization during citric acid production.
