摘要
n-Amyl acetate cannot be completely removed from n-amyl acetate - n- amyl alcohol - water mixtures by distillation because of the presence of the minimum ternary azeotrope. n-Amyl acetate can be readily removed from mixtures containing it, n-amyl alcohol and water by using extractive distillation in which the extractive distillation agent is a higher boiling organic compound or a mixture of these. Typical examples of effective agents are ethylene glycol; propylene glycol and dimethylsulfoxide; 1,3-butanediol, dimethylformamide and acetamide.
