Steps:
The procedure for the esterification
General procedure: Acidic pseudo-IL (0.05 g) was loaded into a 50-mL threenecked flask with a magnetic stirrer, and a reflux condenser. A Dean-Stark apparatus was used to remove the water continuously from the reaction mixture. n-Butanol (14.8 g,0.2 mol) and aliphatic acid (with -OH/-COOH molar ratio = 1.5:1) were added and reaction was carried out under reflux condition. The reaction progress was monitored by the acid-base titration. The conversion of the reaction was calculated on the acidity using the following equation: Conversion (%) = [1 - (final acidity)/(initial acidity)] × 100%. Here, the acidity from acidic pseudo-IL was excluded. For final and initial acidity, the acidity from the pseudo-IL was subtracted. The products were confirmed using GC-MS analysis. After reaction, the IL was separated from the reaction mixture by cooling the temperature, which made the catalyst recovery quite simple.
