Abstract

The invention relates to an adamantane-containing quaternary ammonium salt ionic liquid and a preparation method thereof. The structural formula of the adamantane-containing quaternary ammonium salt ionic liquid designed and prepared by the invention is shown in the specification, and in the formula, n is equal to 6, 9 or 11. According to the adamantane-containing quaternary ammonium salt ionic liquid disclosed by the invention, 1-adamantanecarboxylic acid is used as a raw material, and the ionic liquid is prepared by the following three steps: firstly, carrying out acylating chlorination reaction on 1-adamantanecarboxylic acid and thionyl chloride to synthesize 1-adamantanecarbonyl chloride, carrying out esterification reaction on the 1-adamantanecarbonyl chloride and OH(CH2)nBr, and thencarrying out quaternization with N,N-dimethylbenzylamine to form the adamantane-containing quaternary ammonium salt ionic liquid. The adamantane-containing quaternary ammonium salt ionic liquid obtained in the invention has the characteristics of mild reaction conditions, easily available raw materials and high product purity, and has potential application prospects in the fields of supramolecular chemistry, catalysis, batteries, nano materials and the like.

Description

technical field [0001] The invention relates to an adamantane-containing quaternary ammonium salt ionic liquid and a preparation method thereof. Background technique [0002] As a new type of environmentally friendly "green solvent", ionic liquids have many unique properties and have attractive application prospects in many fields. Adamantane (tricyclo[3.3.1.1 3,7 ]Decane) is a cyclic tetrahedral hydrocarbon composed of 10 carbon atoms and 16 hydrogen atoms, and the entire ring system has a symmetrical and highly stable structural feature. This rigid ring system and positive symmetric structure determine that adamantane and its derivatives have unique physical and chemical properties: non-toxic, tasteless, high density, high melting point, good thermal stability, good fat solubility, high biological activity, antiviral Strong, extremely lipophilic, etc. By introducing adamantyl groups into ionic liquids, various types of ionic liquids can be designed and synthesized, and ...
