Abstract

ABSTRACT Polyesters are important materials with a wide range of applications, but there has been increasing concern over their sustainability. One example is the need for safer, bio-derived solvents to replace those currently in use for the polymer’s synthesis and processing. In this work, several variants of the bio-based cellulose/levoglucosenone derived solvent Cyrene, namely the ketal derivatives dioxolane Cygnet, dioxane Cygnet and dioxepane Cygnet were synthesized and tested as media for enzymatic polycondensation reactions using bio-based building blocks. Dioxolane Cygnet and dioxepane Cygnet were found to be suitable solvents for enzymatic polycondensation reactions, with dioxolane Cygnet being the preferred solvent, yielding polymers with a Mn >22 kDa. In addition, these solvents were tested in the biocatalyzed synthesis of levoglucosenone-based polyesters. The alternative solvents gave superior yields to those previously observed, demonstrating the versatility of these solvents in enzymatic polycondensation reactions, representing the first synthetic polymer-solvent system fully derived from cellulose.

期刊介绍： Green Chemistry Letters and Reviews is an Open Access, peer-reviewed journal focused on rapid publication of innovative new syntheses and procedures that reduce or eliminate the use and generation of hazardous materials. Reviews of state-of-the-art green chemistry technologies are also included within the journal''s scope. Green Chemistry Letters and Reviews is divided into three overlapping topic areas: research, education, and industrial implementation. The journal publishes both letters, which concisely communicate the most time-sensitive results, and reviews, which aid researchers in understanding the state of science on important green chemistry topics. Submissions are encouraged which apply the 12 principles of green chemistry to: -Green Chemistry Education- Synthetic Reaction Pathways- Research and Process Analytical Techniques- Separation and Purification Technologies- Renewable Feedstocks- Degradable Products
