Ltd., Jilin 132101, China GR APHICAL A BSTRACT ARTICLE I NFO ABSTRACT Keywords: The transesteriﬁcation of palm oil and mixed dimethyl/diethyl carbonate (DMC/DEC) was investigated to Biodiesel produce glycerol-free biodiesel with improved cold ﬂow performance. The potassium hydroxide (KOH) was used Glycerol-free as the cheap heterogeneous catalyst. The biodiesel yield could reach 90.8% and the molar ratio of FAMEs/FAEEs Mixed dimethyl/diethyl carbonate was ﬁxed as 2:1 over the following optimal reaction conditions: Molar ratio of DMC/DEC was 1:1, molar ratio of Cold ﬂow properties mixed DMC/DEC and oil was 14:1, KOH amount was 15 wt% (based on the oil), reaction temperature was 100 °C
