High-Performance Purification of Carboxylic Acids
PUREXIS®
Advanced Purification for High-Value Molecules
The purification of carboxylic acids is one of the most complex challenges in bio-based chemistry. Many molecules have physicochemical properties that are extremely similar, making their separation difficult and often limiting the ability to achieve high levels of purity.
To address these challenges, BKB Chemicals has developed PUREXIS®, a proprietary advanced purification technology designed to efficiently isolate molecules of interest while preventing their degradation.
01
Separating the Inseparable
Certain molecules, particularly bio-based carboxylic acids, have very similar characteristics, which make separating them particularly complex on an industrial scale.
Through a combination of advanced selective extraction techniques, controlled purification, and optimization of physicochemical equilibria, PUREXIS® produces high-purity ingredients that meet the requirements of even the most demanding markets.
02
Preserving sensitive molecules
Many molecules of interest are heat-sensitive and can degrade during conventional purification processes.
PUREXIS® was designed to limit the exposure of products to excessive thermal stress and reduce the risk of degradation that could compromise their quality and stability.
This control helps preserve the integrity of the molecules throughout the process.
03
Maximizing the Value of High-Value-Added Molecules
The extraction of heat-sensitive compounds becomes particularly complex when they are present in mixtures containing substances that are much less volatile or have high boiling points. Thanks to its innovative approach to purification, PUREXIS® enables the efficient recovery of these target molecules while maintaining a high level of purity and quality.
