In this paper, soybean oil and palm oil with methanol and methanol to obtain fatty acid methyl ester interchange reaction catalyst as NaOH. Study of NaOH catalyst, stirring speed, reaction time and reaction temperature and other operating conditions of the reaction using gas chromatograph detector elements yield different reaction products of fatty acid methyl esters. Optimal conditions for experiments, to study the transesterification reaction of soybean oil was: 1.1% amount of catalyst, stirring speed 400rmp, reaction time 60min, the reaction temperature is 60 deg.] C; the optimum conditions for the transesterification of palm oil: 0.5% amount of catalyst , stirring speed 700rmp, reaction time 60min, the reaction temperature is 50 ℃.

In this paper, soybean oil and methanol, as well as palm oil and methanol in NaOH as a catalyst for ester exchange reaction to obtain fatty acid methylester. The effects of operating conditions such as catalyst NaOH dosage, stirring speed, reaction time and reaction temperature on reaction were studied, and the yield of fatty acid methylesters in different reaction factors was detected by meteorological chromatograph. Through experiments, the optimal conditions for soybean oil ester exchange reaction were: 1.1% of the catalyst, 400rmp at stirring speed, 60min reaction time, 60oC reaction temperature, and the optimal conditions for palm oil ester exchange reaction were 0.5% of the catalyst, 700rmp of stirring, 60min reaction time, 50c reaction temperature.

In this paper, fatty acid methyl esters were synthesized by transesterification of soybean oil with methanol and palm oil with methanol using NaOH as catalyst. The effects of catalyst NaOH dosage, stirring speed, reaction time and temperature on the reaction were studied. The yield of fatty acid methyl ester in the products with different reaction factors was measured by GC. Through experiments, the optimal conditions of soybean oil transesterification are: catalyst dosage 1.1%, stirring speed 400 RMP, reaction time 60 min, reaction temperature 60 ℃; Palm Oil Transesterification: catalyst dosage 0.5%, stirring speed 700 RMP, reaction time 60 min, reaction temperature 50 ℃.<br>
