Dihydrogen Phosphated Ionic Liquid; An Efficient Catalyst for Biodiesel Production

Dihydrogen phosphated ionic liquid (DHP-IL); a bifuntionalized acidic ionic liquid was prepared and employed for esterification and transesterification of sunflower oil. Optimized conditions was selected by employing of novel dihydrogen phosphated ionic liquid (DHP-IL) as catalyst. The results showed that present novel ionic liquid was very efficient and recyclabe catalyst for the preparation of biodiesel. The yield of product increases with the decrease of steric hindrance of employed alcohol. All of conversions were measured by high performance liquid chromatography (HPLC).
