Centrifugal partition chromatography: Isolation of mono-aromatic compounds from oxidatively depolymerized lignin

The rise of biorenewable alternatives and petroleum/fossil-derived chemicals have led to a growing interest in lignin valorization. When lignin is depolymerized, it generates valuable mono-aromatic compounds and a diverse range of oligomeric compounds. The complexity of this mixture requires purification; however, the identity and low abundance of the desired monomers demand high-resolution techniques that are often fouled by the high molecular weight oligomers.

In this webinar, join Dr. Manar Alherech as he demonstrates the feasibility of isolating valuable compounds, such as vanillin and p-hydroxy benzoic acid, among others, from an oxidative lignin depolymerization matrix using centrifugal partition chromatography (CPC). Alherech will also explore CPC, a readily scalable chromatographic technique, and how CPC can facilitate easy scale-up.

Key learning objectives:

• Understand the challenges of lignin valorization in the modern biorefinery
• Learn more about mediated lignin oxidations developed at UW-Madison
• Gain an understanding of the basics and history of CPC
• Learn about the purification of an oxidative, alkaline lignin depolymerization residue by CPC

Who should attend?

• Lignocellulosic biomass researchers
• Chemical engineers
• Biorefiners
• Purification specialists interested in CPC
