设计了中试实验装置，在高真空度及低压差条件下，进行MDI同分异构体及水分解氯的同时分离的实验研究，实验结果表明产品4，4，体MDI的纯度可达99％以上，水解氯含量少于0.0028％，且可以防止二聚体的生成，MDI的收率可达98％以上。
설계료중시실험장치，재고진공도급저압차조건하，진행MDI동분이구체급수분해록적동시분리적실험연구，실험결과표명산품4，4，체MDI적순도가체99％이상，수해록함량소우0.0028％，차가이방지이취체적생성，MDI적수솔가체98％이상。
The pilot is designed to carry out the experimental study of the synchronous separation process of MDI isomer and hydrolyzable chloride under the condition of high vacuum degree and low pressure difference. The experiment testified that the 4, 4＇-isomer＇s content can reach 99% with the content of hydrolyzed chlorine lower than 0. 0028% and prevent the generation of dimer and that the yield of MDI can reach 99%.
