Optimization of biodiesel production from palm oil under supercritical ethanol conditions using hexane as co-solvent: A response surface methodology approach

- Conversion of palm oil to ethyl esters at supercritical ethanol conditions.
- Hexane as a co-solvent to accelerate the transesterification process.
- Ethyl esters analyzed with GC-MS, FT-IR, and TGA.
- A response surface methodology to design and optimize the conversion process.
