“…Furthermore, this group suggested that the above enzymatic transesterification reaction followed the Ping–Pong Bi–Bi mechanism, and the use of [BMIM][PF 6 ] actually lowered the initial reaction rates due to mass transfer limitations around the immobilized lipase. Ha et al . demonstrated a continuous operation (0.375–0.75 mL h ‐1 ) of Novozym 435‐catalyzed transesterification of vinyl laurate and 1‐butanol in [OMIM][OTf] through a double‐layer type continuous stirred tank reactor (Fig.…”

During the past decade, ionic liquids (ILs) have gained tremendous attention in nearly every branch of the chemical and physical sciences as designer (task‐driven) and budding ‘green’ solvent alternatives to conventional volatile organics. In particular, with a more in‐depth understanding of their physicochemical properties, the active exploration of ILs as alternative solvents and/or catalysts in the chemical or enzymatic (biocatalytic) production of biodiesel has gained momentum. Most excitingly, very recent developments in the science of deep eutectic solvents (DESs) have initiated potentially more cost‐effective approaches to biodiesel synthesis. At this stage, there is sufficient research completed to provide an important opportunity to stand back and assess the progress in the field, critically examining the strengths and limitations for IL and DES technology in biodiesel synthesis. No such comprehensive evaluation exists. This work, therefore, seeks to bridge this gap by systematically reviewing the reported methods for biodiesel production which make use of ILs, either as (co)solvent components or catalysts, highlighting existing problems and limitations, with an emphasis placed on the future research required to bypass the hurdles to employing ILs in commercial biodiesel production.

“…It has been widely reported that the enzymatic in situ saccharification of cellulose in aqueous‐IL media could simplify the entire process from cellulose to biofuel (e.g. washing and drying process), because ILs favor natural biomass conversion to sugars . However, separation and recovery of ionic liquid from a mixture (e.g.…”

“…A screening of twenty three ILs was carried out, obtaining the best results with [EMIM]TfO after 12 hours at 50 °C. The production yield of 80% was eight times higher compared to the conventional solvent-free system (Ha et al, 2010). Ruzzi and Bassi introduced the use of methyl acetate as the acyl acceptor in the place of the more commonly used methanol due to the negative effects methanol and the glycerol byproduct has on lipase enzyme activity.…”
