| Abstract: | n-Butyl propionate was synthesized from n-butanol alcohol and propionic acid in the presence of SO42-/TiO2-La2O3.The factors influencing the synthesis were discussed and the best conditions were determined. The optimum conditions are as follows: molar ratio of n-butanol alcohol to propionic acid is 1 .2 :1, the quantity of catalyst is equal to 2.5% of feed stocks,and the reaction time 1.5 h.SO42-/TiO2-La2O3 is an excellent catalyst for synthesizing n-butyl propionate and its yield can reach over 83.6 % . |
