Abstract:Heteropoly acid compound PW-ZrO2-SiO2,which was prepared in our laboratory,was used for catalyzing the synthesis of trimethylolpropan (TMP) polyester plasticizer from the reaction of TMP and adipic acid. Heptanoic acid was used as end capping agent. Optimum reaction conditions were achieved as follows:n(TMP)∶n(adipic acid)∶n(heptanoic acid)=1∶1∶1.2,reaction time 1.5 h,catalyst load 5%,temperature 140~144℃. FT-IR,1H NMR and 13C NMR were used for characterizing the structure of the product. |
Key words:PW-ZrO2-SiO2;polyester plasticizer;trimethylolpropane |
