| Abstract: | Synthesis of trioctyl citrate using resin as the catalyst.The main factors,including quantity of the catalyst,reaction temperature,mole ratio of reactants and reaction time were investigated.The results showed that: the esterification reaction was conducted at about 150℃ in the presence of resin using about 10% by weight of citric acid,mole ratio of citric acid to 1-octanol was l∶4.5,the yield was up to 97% after 1.5 h.The catalyst is easily separated from product and reusable. |
