This paper mainly studies the reaction process of transesterification of soybean oil, palm oil and methanol with NaOH as catalyst to prepare biodiesel. The effects of operating conditions such as catalyst dosage, stirring speed, reaction time and reaction temperature on the transesterification of soybean oil and palm oil were studied through single factor experiments. The conversion rate of raw oil and biodiesel of different reaction factors were detected by gas chromatography The yield. Through experiments, the optimal conditions for the transesterification reaction of soybean oil were: catalyst dosage 1.1%, stirring speed 400 rpm, reaction time 60 min, reaction temperature 60 ℃; optimal conditions for palm oil transesterification reaction: catalyst dosage 0.5%, stirring speed 700 rpm, reaction time 60 min, reaction temperature 50 ° C. <br>Keywords: soybean oil; palm oil; homogeneous base NaOH catalyst; transesterification; biodiesel

This paper mainly studies the reaction process of soybean oil and palm oil and methanol to use NaOH as a catalyst for ester exchange to prepare biodiesel. The effects of operating conditions such as catalyst dosage, stirring speed, reaction time and reaction temperature on soybean oil and palm oil ester exchange reaction were studied by single-factor experiments, and the conversion rate of raw oil of different reaction factors and the yield of biodiesel were detected by gas chromatograph. Through experiments, the better conditions for soybean oil ester exchange reaction were: 1.1% of the catalyst, 400 rpm of stirring, 60 min reaction time, reaction temperature of 60 degrees C, the better conditions of palm oil ester exchange reaction were: 0.5% of the catalyst, 700 rpm of stirring speed, reaction time of 60 min, reaction temperature of 50 degrees C.<br>Keywords: soybean oil; palm oil; homogenous naOH catalyst; ester exchange reaction; biodiesel
