Hardcover Abstract: Volume II/24 presents the spectroscopic data on diamagnetic and paramagnetic molecules as well as on molecular ions and radicals up to date considering the publications up to and partly including 1997. The spectroscopic information collected in this volume has been obtained principally from gas phase microwave measurements. Volume II/24 is a supplement to volumes II/4, II/6, II/14, and II/19 and is planned to appear in five subvolumes, the last of which will contain the substance index taking into account all molecules worked at since 1967 in the volumes mentioned and will provide cross references to and between all tables of these. The present subvolume II/24B contains an introduction and tables of rotational and centrifugal distortion constants of asymmetric-top molecules, i.e. data which roughly specifies the frequencies of the rotational transitions of these types of rotors.

• 方法一:主要作为合成甲醇生产中的副产获得，但随着以铜基催化剂为基础的低压法甲醇技术的广泛应用，甲醇粗产物中的二甲醚含量已很少。小规模生产时，可采用甲醇催化脱水法的方法，有液相法和气相法两种。液相法是将甲醇和硫酸的混合物加热得到二甲醚。气相法是将甲醇蒸气通过氧化铝或结晶硅酸铝（也可用ZSM-5型分子筛）固体催化剂，气相脱水生成二甲醚。实验室中可由原甲酸三甲酯以三氯化铁为催化剂分解而得（收率95%）。高纯度甲醚可由碘甲烷与甲醇钠通过威廉逊合成法制得。
