二甲醚的生产、应用及检测

二甲醚是一种性能优良、有发展前景的新燃料,主要有两种制备方法:两步法和一步法。从长远看,一步法生产二甲醚具有较高经济价值,而CO2加氢制取二甲醚是未来的发展方向。二甲醚是理想的能源替代品,它用处广泛,可作为氟氯烃的替代品、民用燃料和车用燃料的替代品,且还可开发出一系列具有高附加值的产品,这也将推动我国二甲醚合成技术工业化的进程。最后对二甲醚的检测方法做了介绍。

The Production,Application and Detection of Dimethyl Ether

Dimethyl ether is a new fuel which has good performance and the future development. There are mainly two preparation methods：two-step method and one-step method. From a long term,one-step production has high economic value,but the preparation of dimethyl ethe from CO 2 and hydrogenation is the future direction. Dimethyl ether is an ideal energy-alternative,which is widely used as the alternative of HCFC, domestic fuel and automotive fuel. The dimethyl ether can also be developed a series of products with high value-added,which will also push the forward of industrial synthesis technology of dimethyl ether. At last, the detection of dimethyl ether is also introduced.
