【Abstract】 Tungstogermanic heteropoly acid H 4GeW 12 O 40 was used as the catalyst for the esterification of capric acid and iso-amyl alcohol in liquid phase.Effects of the amount of the catalyst used,the reaction time,the ratio of reactants and the amount of the agent taking off water from the reaction container on synthesizing iso-amyl caprate were investigated,The suitable condition for synthesizing the ester was obtained.Under the optimum conditions,the esterification ratio could reach 98 7%.更多还原
