Methacrylation. 10 g of EMO was placed in a round-bottom flask wrapped in aluminum foil. Hydroquinone (HQ) (0.25% w/w) and triphenylphosphine (1 or 2% ww/w) were added while stirring at 200 rpm. After both the solids were solubilized, 2,8 mL of methacrylic acid was added dropwise using a syringe, and the reaction was heated at 105 °C. The reaction was stopped after 15 h and the methacrylated epoxidized microalgal oil (MEMO) was diluted with ethyl acetate and washed with MilliQ water and NaHCO3 to eliminate the methacrylic acid. The organic phase was washed with brine and dried with anhydrous sodium sulfate at room temperature. The solvent was removed by vacuum, to obtain the methacrylated epoxidized microalgal oil (MEMO).
