干水（DW）是一种以空气代替普通有机溶剂作为非极性连续相的皮克林乳液。干凝胶（DG）也被制备出来，它是一种上级优于DW的有前途的可循环气体储存或气体分离材料。在这两种“干物质”的基础上，我们又增加了一个新成员--干离子液体（D-IL）。由于非挥发性，D-IL没有DW和DG的致命缺陷，即，在开放系统中由于水的暂时蒸发而导致的坍塌。D-IL的化学惰性也为绿色化学提供了潜在的应用，例如，一种无有机溶剂微型反应容器，本研究首次成功地制备了D-IL，并讨论了IL的性质、IL/SiO2组成和含水量等制备条件。
Dry water (DW) is a kind of Pickering emulsion, where air serves as the nonpolar continuous phase in place of common organic solvents. Dry gel (DG) has also been prepared, which is superior to DW as a promising material for recyclable gas storage or gas separation. Here we add a new member, dry ionic liquid (D-IL), to those two kinds of ‘‘dry matter’’. Because of the non-volatility, D-IL is free from the fatal defect of DW and DG, i.e., collapse due to the temporal water vaporization in an open system. The chemical inertness of D-IL also provides potential applications for green chemistry, e.g., an organic solvent-free micro reaction vessel. In this study we report the first successful preparation of D-IL and discuss the preparation conditions such as properties of IL, IL/silica composition and water content.
