The alkali-catalyzed transesterification of vegetable oils into Bio-diesel using 1vol% emulsifier at 60°C was performed on the rotary viscometer. The viscosity of fatty acid methyl ester was predicted by Orrick and Erbarr' s model. The overall yield increased as the viscosity decreased. The limiting molar ratio of methanol to oil appeared to be 1:5 due to 1vol% emulsifier. The sodium hydroxide was shown to be the optimum catalyst and its content appeared to be 0.5wt%. The overall yield(%) of fatty acid methyl ester from canola oil was 95%.
