| Abstract: | The preparation of biodiesel oil from soybean oil was investigated by transesterification using Na2CO3/MCM-41 as solid catalyst that took MCM-41 as carrier to charge Na2CO3.Effects of the amount of catalyst,the molar ratio of reactants,reaction temperature and time on reaction were studied.The results on reaction showed that the optimal reaction conditions was that n(methanol) ∶n(soybean oil)=16 ∶1,catalyst amount was 3% soybean oil quality,the reaction temperature was 60 ℃,reaction time was 3 h,ester exchange conversion rate is up to 35%. |
