Technical Field

[0001] The utility model relates to the technical field of separation of isoamyl alcohol and isoamyl acetate, in particular to a device for separating isoamyl alcohol and isoamyl acetate. Background Art

[0002] Isoamyl acetate is a colorless transparent liquid, insoluble in water, mainly used as a solvent, and can be miscible with organic solvents such as ethanol, ether and ethyl acetate, and can dissolve paint, resin, chloroprene rubber, etc. Industrial isoamyl acetate is mostly obtained by esterification reaction of acetic acid and isoamyl alcohol. Isoamyl acetate is often inevitably mixed with impurities such as isoamyl alcohol, and a separation device is needed to separate it. At present, the commonly used separation method is to add a separation aid and a catalyst to the mixed liquid, so that the relative volatility of isoamyl alcohol and isoamyl acetate changes greatly, reducing the difficulty of separation between the two, and then separating isoamyl alcohol and isoamyl acetate by an extractive distillation method; However, in the prior art, the separation aid and the catalyst are usually directly added to the mixed liquid, lacking an auxiliary stirring mechanism, and the separation aid, the catalyst and the mixed liquid cannot be quickly mixed, which easily leads to a reduction in reaction rate, affecting the separation effect of isoamyl alcohol and isoamyl acetate, and is inconvenient to use. Therefore, we propose a separation device for isoamyl alcohol and isoamyl acetate. Utility Model Content
