中文摘要：
汽油中含氧化合物的添加不仅可以提高燃料的燃烧效率，还能有效降低废气中一氧化碳和碳氢化合物等有害物质的排放。由于能有效提高辛烷值，且与油品中有机化合物具有良好的互溶性，MTBE（甲基叔丁基醚）成为现阶段国内油品调合组分中最重要的一环。但是，近年来的研究发现其对地下水源污染较严重且对人的健康存在巨大威胁。ETBEf乙基叔丁基醚）由于在理化性质方面的优越性，原料的来源廉价，对环境没有污染，被认为是MTBE最佳的替代物。本文综述了ETBE的生产工艺，并详细阐述了近几年国内外在ETBE的合成与分离方面的最新进展，最后对ETBEI业生产及发展方向进行了展望。
英文摘要：
Oxygenate additives in fuel could increase combustion quality and reduce particulate emission and carbon monoxide pro- duction. Because of its improvement in octane rating and good solubility in organic compounds, methyl tert-butyl ether （MTBE） was introduced into gasoline as one of important parts. However, studys reported that MTBE was frequently found in the urban ground water and classified MTBE as a health risk threat to human. Ethyl tert-butyl ether （ETBE） was chosen as an alternative fuel oxygen- ate because it had superior qualities than MTBE in toxic effect and reid vapor pressure, and could be produce from renewable sourc- es. The synthesize of ETBE from IB and TBA in liquid phase and the separation techniques were critically reviewed. Suggestions about the future research on ETBE production were also addressed.
