Research by Alenezi Raslan (2010) highlights the significant impact of process conditions on chemical yields. Their work demonstrated that non-catalytic hydrolysis using subcritical water in a continuous flow reactor could achieve up to 92% FFA yield by carefully controlling temperature (350°C), pressure (20 MPa), and the water-to-oil volume ratio (50:50). This underscores the importance of precise parameter control in optimizing the production of valuable chemical intermediates.
