| Abstract: | An experiment was made on the transesterification of jatropha curcas oil and subcritical methanol with p - toluene sulphonic acid as catalyst to prepare methyl esters （biodiesel）. The results indicated that the optimum technical conditions were： reaction temperature 170℃, molar ratio of methanol to oil 40 ： 1, mass ratio of catalyst to oil 0.75% and reaction time 30 rain. Under the conditions, the methyl esters （biodiesel） produced could be over 93% of the reaction resultants. The biodiesel fuel obtained from this technology had a similar specification with diesel fuel. Main properties of the biodiesel were comparable with that of ASTMPS121 -99 （USA） and No. 0 diesel oil. |
