摘要

为了得到质量分数大于97%的C₇F₁₄O，采用化工软件Aspen Plus中的WILS-HF模型进行模拟，理论塔板数为50，去除杂质时回流比为3，收集C₇F₁₄O产品时回流比为10，模拟得到的C₇F₁₄O收率为46.13%。试验结果得到的C₇F₁₄O收率为44.46%，与模拟结果一致，为工业放大提供了参考。

Abstract

In order to obtain C₇F₁₄O with mass fraction more than 97%,the simulation is carried out by using WILS-HF model in Aspen Plus chemical software.The yield of C₇F₁₄O simulated by the software reaches 46.13% when the number of theoretical plates is 50,and the reflux ratio is 3 for removing impurities operation and 10 for collecting C₇F₁₄O products.The yield of C₇F₁₄O obtained in the experiment is 44.46%,consistent with the simulation result,providing reference for industrial amplification.
