Structural Properties of Coniferyl Alcohol-Based Low Transition Temperature Mixtures.

ABSTRACT: This study examines the structural organization of low transition temperature mixtures (LTTMs) based on coniferyl alcohol, a primary monolignol, at the macroscopic and microscopic levels. The work presents the first investigation into the use of lignin-derived monomers as constituents of LTTMs. The LTTMs prepared with 2:1 and 3:1 molar ratios of coniferyl alcohol to choline chloride exhibited glass transition temperatures (T _g) of -24.6 and -16.8 °C, respectively, and with no observable melting points (T _m). The respective water contents were 0.4790 and 0.7564 wt %, similar to that reported for other natural deep eutectic solvents. Time-domain nuclear magnetic resonance analysis revealed that these LTTMs are heterogeneous and exhibited two regions betwee
