The ethyl acetate purification system and the chromatographic pure ethyl acetate production system relate to the technical field of chemical product purification. The ethyl acetate purification system can accurately measure the temperature of the condensate in the reflux tank through the second temperature sensor, and the first temperature sensor can accurately measure the temperature of the condensate in the reflux tank. Measure the temperature of the top of the rectification tower, combine the temperature of the condensate and the temperature of the top of the rectification tower, to determine the amount of condensate that is refluxed to the top of the tower, so that the temperature at the top of the tower is maintained in a relatively constant range , In order to ensure the effect of rectification. At the same time, the industrial-grade ethyl acetate is distilled and purified once before the rectification, which further improves the purification effect of the rectification process. The chromatographic pure ethyl acetate production system includes the above-mentioned ethyl acetate purification system and ethyl acetate preparation system, and has simple equipment, convenient operation and good purification effect, and can be used for large-scale industrial production.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. keeps pace with the times and develops 10% polyethylene adipate/401 organic carrier packed column, thermal conductivity detector, and area normalization method for the determination of chromatographic pure ethyl acetate Purity and impurities, high column efficiency, good separation, and area normalization method for quantification.
