摘　　要：研究V2O5-Fe2O3催化剂对甲醇-乙醇一步合成异丁醛反应的催化性能.在反应温度为653 K、空速为2.72 h-1的实验条件下,乙醇的转化率和异丁醛的选择性随着V含量的增加,先增加后降低,当V2O5质量分数为80%、Fe2O3质量分数为20%时,有较好的催化效果,乙醇的转化率为84.1%,异丁醛的选择性为43.3%.当Fe与V形成Fe0.12V2O5.16结构时,对甲醇乙醇合成异丁醛反应有较好催化效果.This paper investigated V2O5-Fe2O3 Catalyst for Synthesis of Isobutyraldehyde from Methanol and Ethanol.Conversion of ethanol and selectivity of isobutyraldehyde increased with V content increasing and then decreased.When the content of V2O5 was 80 %,the content of Fe2O3 was 20 %,the reaction temperature was 653 K,and space velocity was 2.72 h-1,the good catalytic effect was achieved ：ethanol conversion rate was 84.1 % and the selectivity of isobutyraldehyde was 43.3 %.When the structure of Fe0.12V2O5.16 was formed by Fe and V,it had a better catalytic effect on the synthesis of isobutylaldehyde with methanol and alcohol.
