水具有溶解許多物质的能力,大多数化学反应都是在水中进行,这是由于水具有很好的溶剂性能。同时在自然界中也是取之不尽的一种天然溶剂,因此在无机化学中水占着特殊重要地位,但是除水之外,还有很多其他液态介质,也可用作溶剂,特别是制备某些物质或測定它的分子量时,如果在水溶剂中反应会产生不溶解或且分解現象,这时必須在非水溶剂中进行反应。从历史观点来看,对非水溶剂性质的研究大約可以分为三个时期,从1892年开始5～7年間,主要研究有机化合物如酒精,醚和丙酮作为无机物质的溶剂;所得的結果常常是定性的說明,很少有实际应用的科学价值,因为对无机电介质来說其溶解性极有
Water has the ability to dissolve many substances, and most chemical reactions are carried out in water due to the good solvent properties of water. At the same time in nature is also an inexhaustible natural solvent, so water is particularly important in inorganic chemistry, but in addition to water, there are many other liquid medium can also be used as a solvent, especially the preparation of a Some substances or their molecular weight determination, if the reaction in the water solvent will produce insoluble or decomposition phenomenon, then the reaction must be carried out in a non-aqueous solvent. From a historical point of view, the study of the nature of non-aqueous solvents can be divided into about three periods, from 1892 onwards 5-7 years, the main research organic compounds such as alcohol, ether and acetone as a solvent for inorganic substances; the results obtained often Is a qualitative description, there is little scientific value of practical application, because of their solubility in inorganic dielectrics
