| Abstract: | Ionic liquid Hnhm ] absorption of the ionic liquid Hnhm ] H2PO4 was investigated H2PO4 was synthesized and characterized by IR. The solubility and water were studied. The catalytic activity of as-synthesized ionic liquid by using esterification of oleic acid with methanol to methyl oleate as the the condition as follows ： ionic liquid Hnhm] H2PO4 dosage 8% of oleic acid mass ,n（methanol） ： n（ oleie acid） = 3.5： 1, reaction temperature 90 ℃, and reaction time 9 h. The ionic liquid could be easily separa- ted from raw materials and esterification products. |
