  abstract = {<p>Ionic liquid (IL) pretreatment methods show incredible promise for the efficient conversion of lignocellulosic feedstocks to fuels and chemicals. Given their low vapor pressures, distillation-based methods of extracting <a href="https://www.sciencedirect.com/topics/earth-and-planetary-sciences/ionic-liquid">ionic liquids</a> out of biomass post-pretreatment have historically been ignored in favor of alternative methods. We demonstrate a process to distill four acetate-based <a href="https://www.sciencedirect.com/topics/materials-science/ionic-liquid">ionic liquids</a> ([EthA][OAc], [PropA][OAc], [MAEthA][OAc], and [DMAEthA][OAc]) at low pressure and high purity that overcome some disadvantages of {\textquotedblleft}water washing{\textquotedblright} and {\textquotedblleft}one pot{\textquotedblright} recovery methods. Out of four tested ILs, ethanolamine acetate ([EthA][OAc]) is shown to have the most agreeable conversion metrics for commercial <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/bioconversion">bioconversion</a> processes achieving 73.6\&nbsp;\% and 51.4\&nbsp;\% of theoretical glucose and xylose yields respectively and \&gt;85\&nbsp;\% recovery rates. Our process metrics are factored into a techno-economic analysis where [EthA][OAc] distillation is compared to other recovery methods as well as ethanolamine pretreatment at both milliliter and liter scales. Although our TEA shows [EthA][OAc] distillation underperforming against other processes, we show a step-by-step avenue to reduce sugar production cost below the wholesale dextrose price at scale.</p>},
