AB Non-polar oil and polar short-chain alcohols, used as reactants in the transesterification reaction,are immiscible. Transesterification reactions can only occur on the phase boundary and they aretherefore diffusion-limited. Several methods are employed to overcome the limitation of masstransfer by increasing miscibility and thereby accelerating the reaction. Co-solvents are additionalsolvents that should be soluble in the oil and alcohol phase; this could lead to an increase in thereaction rate and a reduction in the temperature and the reaction time. This work aims to providea comprehensive literature review on the influence of co-solvents on the processes of catalysedmethanolysis for the biodiesel production. Most authors have not systematically determined andjustified the effects of cosolvents. So far it seems impossible to establish which cosolvents are themost suitable for which methanolysis systems. The purpose of this work is to highlight and justifythe differences or similarities in co-solvent impacts among the various publications by examiningthe chemical structure of the respective co-solvents, including the functional groups and theresulting physicochemical properties such as the dielectric constant or the log P value. Besidesbiodiesel, co-solvents like THF and acetone seems to be the best choices for alkaline methanolysissystems due to successful broadly applications with different oils, catalysts and reaction conditions. Moreover, THF and n-hexane are essentially advisable for in-situ methanolysis.
