摘　　要：介绍了氢氟醚类有机朗肯循环低温热源工质三氟甲基甲醚、甲基五氟乙醚、2,2,2-三氟乙基二氟甲基醚、六氟异丙基甲醚、七氟-1-甲氧基丙烷、甲基全氟丁基醚、乙基全氟丁基醚、1,1,1,2,2,3,4,5,5-十氟-3-甲氧基-4-(三氟甲基)戊烷、3-乙氧基-1,1,2,3,4,5,5,6,6,6-十氟-2-(三氟甲基)己烷的物理性质以及合成研究进展。对现有制备方法的分析表明,目前的工艺普遍存在制造成本较高,不易应用于工业化生产的瓶颈,寻找便宜的起始原料和取代硫酸二甲酯的甲基化是优化工艺路线的关键。The physical properties and synthesis research progress of trifluoromethyl methyl ether,methyl pentafluoroethyl ether,2,2,2-trifluoroethyl difluoromethyl ether,hexafluoroisopropyl methyl ether,heptafluoro-1-methoxypropane,methyl perfluorobutyl ether,ethyl perfluorobutyl ether,1,1,1,2,2,3,4,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane,3-ethoxy-1,1,2,3,4,5,5,6,6-decafluoro-2-(trifluoromethyl)hexane,which are low-temperature heat source working fluids of hydrofluoroether organic Rankine cycle,are introduced.The analysis of the existing preparation methods shows that the current process generally has a high manufacturing cost and is not easy to be applied to the bottleneck of industrial production.Finding cheap starting materials and methylation of substituted dimethyl sulfate is the key to optimizing the process route.
