Canola oil was transesterified using a 1 : 1 molar mixture of methanol and ethanol (M/E) with potassium
hydroxide (KOH) catalyst.
The effects of catalyst concentration (0.
5–1.
5 wt-%), molar ratio of M/E to
canola oil (3 : 1 to 20 : 1) and reaction temperature (25–75 7C) on the percentage yield measured after 2.
5
and 5.
0 min were optimized using a central composite design.
A maximum percentage yield of 98% was
obtained for a catalyst concentration of 1.
1 wt-% and an M/E to canola oil molar ratio of 20 : 1 at 25 7C at
2.
5 min, whereas a maximum percentage yield of
