Abstract EN
Biodiesel was prepared from Citrullus colocynthis oil (CCO) via a two-step process.
The first esterification step was explored in two ionic liquids (ILs) with 1,3-disulfonic acid imidazolium hydrogen sulfate (DSIMHSO4) and 3-methyl-1-sulfonic acid imidazolium hydrogen sulfate (MSIMHSO4).
Both ILs appeared to be good candidates to replace hazardous acidic catalyst due to their exceptional properties.
However, the two sulfonic chains existing in DSIMHSO4 were found to increase the acidity to the IL than the single sulfonic chain in MSIMHSO4.
Based on the results, 3.6 wt% of DSIMHSO4, methanol/CCO molar ratio of 12 : 1, and 150°C offered a final FFA conversion of 95.4% within 105 min.
A 98.2% was produced via second KOH-catalyzed step in 1.0%, 6 : 1 molar ratio, 600 rpm, and 60°C for 50 min.
This new two-step catalyzed process could solve the corrosion and environmental problems associated with the current acidic catalysts.
