摘　　要：采用直流负高压电晕放电,在强还原环境下研究乙醇蒸汽与氨气的反应。考察了乙醇和氨水的体积比、反应温度、反应时间、放电频率对乙醇转化率的影响。结果表明:在常压100℃、放电频率为9.608 kHz、反应时间为50min、乙醇∶氨水=7mL∶40mL时,乙醇的转化率可以达到38%。此外,对乙醇氨化合成乙胺的机理进行了初步的探索。The reaction of ethanol and ammonia, in strongly reducing environment with DC negative corona discharge,was investigated. The effect of volume ratio of ethanol and ammonia, reaction temperature, reaction time and discharge frequency on the ethanol conversion was studied. The results showed that, when reaction conditions were as follow: atmospheric pressure,100 oC, the discharge frequency 9.608 kHz, the reaction time 50 min, ethanol: ammonia(aqueous)= 7 mL: 40 mL, the conversion of ethanol reached 38%. In addition, the synthesis mechanism of ethylamine from ethanol and ammonia was also discussed.
