Abstract:
      Dodecyl ferulate was synthesized by ferulic acid and dodecyl alcohol using tetraethyl titanate as catalyst, and the product was purified by macroporous adsorption resin. The optimal synthesis conditions were determined by orthogonal experiment as follows:molar ratio of ferulic acid to dodecyl alcohol 1∶5, reaction temperature 140℃, reaction time 10 h, catalyst dosage 4%. Under these conditions, the yield and purity of dodecyl ferulate were 81.8% and 90% respectively. The evaluation result of DPPH method showed that dodecyl ferulate exhibited good DPPH free radical scavenging activity. The evaluation result of Schaal oven-storage method indicated that dodecyl ferulate had better antioxidant effect on siritch at the dose of 0.04%.
