摘要
以活性炭固载磷钼钨杂多酸作为酯化催化剂,催化合成丙酸异戊酯。最佳反应条件为:n(醇)∶n(酸)=1.2∶1,催化剂用量为1.0 g(占反应物之一丙酸质量的9%),带水剂用量为8 mL,反应时间2.5 h。酯收率达84.5%。
i-Amyl pripionate was synthesized using heteropoly acid of phosphorus molybdenum and tungsten supported on activated carbon as the catalyst. Optimum reaction condition was obtained as follows: n (alocohol) : n (acid)=1.2 : 1, catalyst loading = 1.0 g (equivalent to 9 % of reacting propionic acid), water-carrying agent 8 mL, reaction time 2.5 h. i-Amyl pripionate yield of 84.5 % was obtained.
