Chemical Synthesis of Ascorbyl Palmitate in [BMIM]BF4
Scorbyl palmitate is a safty and highly efficient lipophilic antioxidant.It is produced by a novel ionic liquid method: L-ascorbic acid was esterified with palmitic acid to synthesize ascorbyl palmitate,using concentrated sulfuric acid as chemical catalyst in 1-Butyl-3-methy limidazolium terafluoroborate ([BMIM]BF4).The yield of ascorbyl palmitate reached 69.6±1%.
