摘要
以哌嗪、1,4-丁磺酸内酯及硫酸或磷酸为原料,合成了两种基于哌嗪阳离子的磺酸功能化酸性离子液体硫酸氢盐([(HSO3-b)2pi]2+.2[HSO4]-)和1,4-二(4-磺酸基丁基)哌嗪磷酸二氢盐([(HSO3-b)2pi]2+.2[H2PO4]-);利用傅立叶变换红外光谱、核磁共振氢谱和碳谱表征了两种产物的结构,并测定了其熔点、黏度、电导率、热稳定性等物理性质.
Two kinds of bi-HSO3-functionalized ionic liquids based on piperazinum cation, in- cluding 1,4-bis (4-sulfobutyl) piperazinum bis (hydrogen sulfate) coded as (F(HSO3-b)2 pi] [HSO4 ]2) and 1,4-bis(4-sulfobutyl) piperazinum bis(dihydrogen phosphate) coded as (HSO3- b)2pi][H2PO4]2), were synthesized with piperazine and 1,4-butane sultone as well as H2 SO4 or HBPO4 as raw materials. The structure of as-synthesized products was confirmed by Fourier transform infrared spectrometry and nuclear magnetic resonance spectrometry (1 H NMR and ^13C NMR) ; and their physical properties such as melting point, viscosity in water, electrical conductivity in water and ethanol, and thermal stability were determined.
