| Abstract: | Tri-n-butyl citrate(TBC) was synthesized with citric acid and n-butyl alcohol as raw materials and p-toluene sulfuric acid as esterification catalyst.The effects of the ratio of reactants,quantity of catalyst,reaction time,reaction temperature and entraining agent of water on the product yield were investigated and the reuse of catalyst was studied.The product was confirmed by GC and IR.It was shown that the proper reaction conditions were: the molar ratio of citric acid to n-butyl alcohol was 1:4,the mount... |
