Abstract:With reaction distillation process to make acetic acid in used acetic acid solution form acetic ether, achieving the purpose of recovery acetic acid. Four factors that affects the recovery rate of acetic acid such as full reflux time, mol ratio of ethanol and acetic acid, number of column trays and content of H2SO4 in catalyst are investigated. The premium process conditions are determined, which makes the recovery rate of acetic acid greater than 95%.
Keywords:acetic acid  acetic ether  esterification reaction  reaction distillation
