General description
http://www.sigmaaldrich.com/dam/sigma-aldrich/docs/Aldrich/Acta/al_acta_37_1.pdf
三己基十四烷基膦酸二（2，4，4-三甲基戊基）酯是一种膦基离子液体。它可以通过在碱存在下，使三己基（十四烷基）-氯化膦与二（2，4，4-三甲基戊基）次磷酸反应来制备。
Application
它可以作为萃取剂用于液体燃料中二苯并噻吩的萃取脱硫。
Features and Benefits
膦基离子液体具有有趣的属性，例如：
- 室温液体或 T <100°C 时熔化
- 高热稳定性
- 与水不混溶的
- 溶于有机溶剂（然而，当系统中加入过量的水时，会形成三种液相）
- 碱性条件下稳定
Other Notes
一种用作极性溶剂的次磷酸磷鎓盐
