Abstract:
The green synthesis of methyl palmitate as a biodiesel main target compound was developed by the esterification of palmitic acid over deep eutectic solvents (DESs). Eight DESs were assessed as catalysts for the synthesis in this study. The optimal DES was prepared from tetrabuthyl ammonium chloride and acetic acid (1:2), and the methanol and methyl palmitate sample to DES ratio was 1:0.5 (v/v). The reaction was optimized at a methanol/palmitic acid ratio of 10:1 (mol:mol), at 60 °C for 60 min. Under optimized conditions, good calibration curves were obtained at methyl palmitate concentrations, ranging from 0.25 to 2.00 mg/mL, and the inter-day and intra-day relative standard deviations were less than 3 %. Under DES catalysis, the methyl palmitate yield was 92.5 %. Therefore, DESs can be developed as a catalyst for the esterification of methyl palmitate, and have potential applicability in other biodiesel pretreatments.
