Biodiesel synthesis from rapeseed oil catalysed by different ionic liquids
Dang, K.H1, Quignard, F2, Schrive, L3.
The synthesis of biodieselfrom renewable sources has become mmore important today for both
environmental reasons and also the increasing shortage of fossil fuels. The main method for the production
of biodiesel is the transesterification of vegetable oils catalysed by acid, basic or enzymatic catalysts
in homogeneous or heterogeneous phases. This paper presents a new method of biodiesel production
from rapeseed oil by using ionic liquids, which are completely ionic compounds with melting points equal
to or less than 100°C, as catalysts. The SO3H-functional acidic ionic liquids have been successfully
synthesised and were promising catalysts for the transesterification of rapeseed oil with alcohols to
produce biodiesel. 1-(4-sulfobutyl)-pyridinium hydrogen sulfate hada higher rate enhancement compared
tothe other ionic liquids synthesised in this work. Theacidic or lipophilic characteristics of theionic liquids
were found to be key factors in obtaining good reaction rates. In this work, ethanol and propan-1-ol were
more reactive than methanol due to theirgood solubility in the oils. The ionic liquids could be recycled
and the esters of the fatty acids were separated via simple settling.
