| Summary: | Scarcity of petroleum and constant concern over environmental problems caused by diesel fuels has
promoted production of biodiesel from renewable sources. Biodiesel synthesized from transesterification
methods in the presence of catalyst or enzyme requires huge amount of solvent, particularly from alcohol to
affirm high production yield. Inevitably, the process results in bulky waste that demands appropriate
attention. In attempt to tackle the problem, ionic liquid has been identified to be the most potential substitute
for conventional catalyst and solvent required in the biodiesel conversion. Ionic liquid that is widely known as
‘green chemical’ can be synthesized to meet reaction requirement by careful selection of anion and cations,
with correct proportion of each to produce desired mixture. This paper reviews recent applications of ionic
liquid in biodiesel production as catalyst, solvent and co-solvent. Since there are few ways in which ionic
liquid can be categorized, this paper highlights classification of ionic liquids into two major groups; namely
acidic and basic ionic liquid. Discussion on these two groups covers their dual-functions in biodiesel
production which are as solvent or co-solvent and catalyst in the biodiesel production. |
