【Abstract】 The synthesis of hydrocarbon derivatives from methanol and ethanol in one-step was investigated over vanadium catalyst at 623 K and under normal atmospheric pressure. The mole ratio of methanol to ethanol was 2∶1. The ethanol conversion, isobutyraldehyde yield, acetaldehyde and propaldehyde yield respectively reached to 94.04%, 22.88%, 64.68% and 12.56%. The GC-MS analysis results showed that reaction products also consisted of byproducts such as propanol, formaldehyde, methyl ester, olefine aldehyde, 3-methyl butanol and 2-methyl butyraldehyde.更多还原
