Tetra-n-butylphosphonium type ionic liquids with fumarate anion and maleate anion exhibit different physico-chemical properties and different solubility to water in their cis and trans conformations; fumarate showed the usual upper critical solution temperature (UCST) behavior, whereas maleate had highly unusual lower critical solution temperature (LCST) behavior after mixing with water.
含有富马酸根阴离子和马来酸根阴离子的四正丁基鏻型离子液体在其顺式和反式构象中表现出不同的物理化学性质以及对水的不同溶解度;富马酸盐表现出常见的上临界溶液温度(UCST)行为,而马来酸盐与水混合后具有极不寻常的下临界溶液温度(LCST)行为。
