1-丁基咪唑与3-溴丙胺氢溴化物反应，然后进行后处理和阴离子交换，得到了一种含有阳离子和附加胺基的新的室温离子液体。这种新型离子液体与二氧化碳发生可逆反应，以氨基甲酸盐的形式将二氧化碳可逆封存。这种新型离子液体可以反复循环利用，其二氧化碳捕获效率与商业胺隔离试剂相当，而且不挥发，不需要水就能发挥作用。
Reaction of 1-butyl imidazole with 3-bromopropylamine hydrobromide, followed by workup and anion exchange, yields a new room temperature ionic liquid incorporating a cation with an appended amine group. The new ionic liquid reacts reversibly with CO2, reversibly sequestering the gas as a carbamate salt. The new ionic liquid, which can be repeatedly recycled in this role, is comparable in efficiency for CO2capture to commercial amine sequestering reagents, and yet is nonvolatile and does not require water to function.
