Article Synopsis
- The study explored the esterification of succinic acid with oleyl alcohol using immobilized Candida antarctica lipase B (Novozym 435) as a catalyst, employing response surface methodology (RSM).
- A total of 21 experiments were conducted to assess the effects of four variables: temperature (35-65°C), time (30-450 min), enzyme amount (20-400 mg), and alcohol:acid molar ratio (1:1-8:1), and a partial cubic equation provided a high R² value of 0.9853 for modeling the reaction.
- Findings indicated that temperature significantly impacted ester synthesis, with optimal conditions achieving an esterification percentage of 85.0% at 41.1°C
