| Summary: | Ionic liquid is a catalyst which is homogeneous (liquid phase) catalyst. Ionic liquid has been recognize as a potential catalyst in esterification of free fatty acid from waste cooking oil which contain high amount of free fatty acid due to the triglyceride hydrolysis during frying due to its properties which is adjustable by adjusting its combination of cation and anion. It also recognize as a substitution of sulphuric acid in
biodiesel synthesis.
In this project, different combination of cation and anion has been tested by four types of ionic liquid which involve the uses of pyridinium, 1-methyl-3 butylimidazolium (BMIM), 1 -ethyl-3 -methylimidazole (EMIM) as cation and the uses salicylate, sulphate, as an anion. The four types of catalyst can be considered as novel catalyst since no other researchers tried this combination of cation and anion. All this catalyst is characterize first using IR, CHNS and HNMIR spectrometer. Then the catalytic performance test is done for all the catalyst in the esterification reaction of free fatty acid in simulated waste cooking oil. As the result of the catalytic performance only BMIM SCL showed the conversion with only 30% conversion. |
