Data on making uniform lignin building blocks via in-situ real-time monitoring of hydroxyethyl modification.

In this work, a lab-designed apparatus was developed to collect and record the CO amount during the hydroxyethyl modification of lignin. We presented the CO volume amount and the production rate under different reaction conditions (80 - 120 °C and 2 - 6 hrs). Nuclear magnetic resonance spectroscopy was performed to analyze the chemical structure of the hydroxyethyl lignin corresponding with different amounts of CO that evolved during the reaction.
