Disposing of residual cooking oil is a major environmental concern, so its conversion into commercial products is a desirable goal. To design the chemical modification of a domestic waste oil into valuable biochemicals other than biodiesel, we analyzed a series of its samples, collected over a period of three years, using quantitative ¹ H-NMR. This...
