	%X There is growing interest in biodiesel (fatty acid
methyl ester or FAME) because of the similarity in its properties
when compared to those of diesel fuels. Diesel engines operated on
biodiesel have lower emissions of carbon monoxide, unburned
hydrocarbons, particulate matter, and air toxics than when operated
on petroleum-based diesel fuel. Production of fatty acid methyl ester
(FAME) from rapeseed (nonedible oil) fatty acid distillate having
high free fatty acids (FFA) was investigated in this work. Conditions
for esterification process of rapeseed oil were 1.8 % H2SO4 as
catalyst, MeOH/oil of molar ratio 2 : 0.1 and reaction temperature
65 °C, for a period of 3h. The yield of methyl ester was > 90 % in 1
h.
The amount of FFA was reduced from 93 wt % to less than 2 wt %
at the end of the esterification process. The FAME was pureed by
neutralization with 1 M sodium hydroxide in water solution at a
reaction temperature of 62 °C. The final FAME product met with the
biodiesel quality standard, and ASTM D 6751.
