乙基叔丁基醚合成研究进展

Research advances in the synthesis of ethyl-tert butyl ether

乙基叔丁基醚具有较高的辛烷值,是一种环境友好的汽油添加剂。介绍乙基叔丁基醚在不同催化剂上合成的反应机理,综述国内外合成乙基叔丁基醚的催化剂研究现状及国外几种典型的乙基叔丁基醚生产工艺流程。比较不同催化剂的催化活性、稳定性和选择性。指出通过改性提高树脂催化剂的热稳定性是该领域重要的研究方向。国外已拥有成熟的乙基叔丁基醚合成技术,国内大部分还处于研究阶段,应尽快加强技术开发,早日实现产业化。

Ethyl tert-butyl ether（ETBE） has high octane number and is a kind of environmental friendly gasoline additive. The reaction mechanisms for ETBE synthesis on the surfaces of different catalysts were introduced. The research status of the catalysts for ETBE synthesis at home and abroad, and some typical production technologies of ETBE synthesis overseas were reviewed. The catalytic activity, stability and selectivity of different catalysts were compared. It was pointed out that it was an important research direction to improve the thermal stability of resin catalysts by modification in this field. So far, the mature production technology of ETBE has been obtained abroad, and it has been still in research stage domestically. It is necessary to speed up its research and development and complete industrialization domestically.
