Catalytic Synthesis of Isoamyl Acetate by Ion Exchange Resin-Supported (NH<sub>4</sub>)<sub>6</sub>[MnMo<sub>9</sub>O<sub>32</sub>] • 8H<sub>2</sub>O with Waugh Structure

Ion exchange resin-supported (NH 4 ) 6 [MnMo 9 O 32 ]8H 2 O with Waugh structure is used to prepare supported solid catalyst. Performance of this catalyst is researched by means of synthesis of isoamyl acetate. Optimal reaction conditions determined by orthogonal experiment are as follows: acid-alcohol molar ratio is 2.5:1, reaction time is 120 min, catalyst dosage is 0.8 g, dosage of water-carrying agent is 2.5 ml, esterification yield reaches 95.1%. This catalyst is characterized by high catalytic efficiency, easy separation and recovery, absence of environmental pollution and being reusable, etc.
