摘要
离子液体即在室温或接近室温下呈液态的、完全由离子构成的物质,作为环境友好和"可设计性"溶剂正在引起越来越多的重视。它具有熔点低、蒸气压小、酸性可调及良好的溶解度、粘度和密度等特点。本文综述了离子液体的组成、分类、性质、制备和纯化,详细说明了其在石油化工中的应用,如在烷基化、氢化、脱硫等反应中的应用。
The ionic liquids keep liquid state at or near room temperature. As environmentally benign and ＂designer＂ solvents, they are attracting more and more attentions. They have characteristic of low melting point, low vapor pressure, adjustable acidity, strong solubility and high viscosity. The composition, classification, property, preparation and purification of them were reviewed in this paper. The applications in petrochemical technology were discussed, such as alkylation, hydrogenation, and desulfuration etc.
