已经合成并表征了一系列七种新型噻唑基离子液体。为了解噻唑离子液体的理化性质,通过热重分析、差示扫描量热法和粉末 X 射线衍射对化合物进行了表征。发现噻唑鎓硫原子在固体和液态下都会产生独特的分子间相互作用,从而影响材料的性能。通过单晶 X 射线衍射数据的 Hirshfeld 表面分析以及变温粘度法来检查这些相互作用。此外,据观察,几种离子化合物表现出高聚变焓,使其成为热能存储材料的潜在候选者,从而扩大了这类化合物的可能应用。
A process of isolating dihydroxyacetone which is a useful intermediate in organic chemistry as well as being a sun-tanning agent. The process comprises passing a reaction mixture containing dihydroxyacetone in an organic solvent through at least one thin film evaporator to distil dihydroxyacetone separately from the solvent.
