Improved Purification and Control of Molecular Weight of Lignin (2014-078)

This renewable solvent system consisting of hot acetic acid-water mixtures can simultaneously purify, fractionate, and solvate lignins. This approach to purifying and controlling the molecular weight of lignin improves the pulping process and its output. Previous processes can be expensive and have poorly controlled molecular or chemical properties....
