二甲醚（DME）是最简单的醚，其化学式为CH 3 OCH 3，在环境条件下为无色气体。它在轻压下很容易液化，因为它的蒸汽压在25°C时约为0.6 MPa。二甲醚的物理和化学特性与液化石油气非常相似。因此，二甲醚可以通过使用液化石油气处理技术来分配和储存，这意味着二甲醚不需要昂贵的液化天然气油轮或液化天然气终端。二甲醚不含硫和氮，其毒性很低，与液化石油气相似。由于二甲醚燃料的柴油车既不排放烟尘也不排放PM（颗粒物），它是柴油燃料的一种非常清洁的替代品。JFE公司以低成本、大批量生产二甲醚为目标，在二甲醚直接合成技术的开发方面取得了显著进展。在技术开发的基础上，二甲醚开发公司将于2002年至2006年进行100吨/日（100 TPD）二甲醚示范项目。直接二甲醚合成技术将为二甲醚的经济规模化生产开辟一条新的途径。
Dimethyl ether (DME) is the simplest ether having a chemical formula of CH3OCH3 and a colorless gas at an ambient condition. It is easily liquefied under light pressure because its vapor pressure is about 0.6 MPa at 25°C. Physical and chemical characteristics of DME are very similar to those of LP Gas. Therefore, DME can be distributed and stored by using LP Gas handling technology, which means DME does not need costly LNG tankers or LNG terminal. DME contains neither sulfur nor nitrogen, and its toxicity is very low, similar to LP Gas. Since a DME fueled diesel car emits neither soot nor PM (particle matters), it's a very clean substitute for diesel fuel. For the purpose of producing large quantity DME at low cost, JFE Corporation has been making remarkable progress in a development of direct DME synthesis technology. Based on the technology development, DME Development Company is conducting 100-ton-DME/day (100TPD) Demonstration Project from 2002 through 2006. This Direct DME Synthesis technology will open a new way to economical DME mass production.
