Abstract

Biodiesel was prepared by transesterification of soybean oil with methanol,using NaOH as catalyst.The effects of methanol/oil mole ratio,catalyst dosage,reaction time and temperature on the yield were studied.The chemical composition of obtained product was analyzed by GC.The optimum conditions for transesterification were(n(methanol):)n(soybeanoil)= 6∶1,reaction temperature 60 ℃,reaction time 2 h and amount of catalyst 1.0%(based on the oil weight).Under above conditions,the yield of biodiesel was 98.5%.
