Results of calculation indicate that the bubble & dew points may be reduced extremely, but the relative volatility rises slightly and the separation of them is affected hardly by decreasing pressure. and this article puts forward more reasonable modifying suggestions after analyzing numerically in detail the common method of determining the position of sensitive plate in distillation tower and finds out something unsatisfactory about it
計算結果表明，減壓可大大降低乙苯?苯乙烯物系的泡、露點，但相對揮發度增加甚微，對其分離的難易程度幾乎無影響;對常用求取精餾塔靈敏板位置的方法進行了詳盡的數值分析，對其不合理性提出了改進措施。 -
In the course of oxidation, reaction temperature should rise step by step, and in the late stage, reduced pressure distillation should follow so that the concertration of glyoxalic acid can rise and production rate of allantoin can rise up to 40 %
在氧化反應的過程中逐步地提高反應溫度，反應後期進行減壓濃縮，提高了乙醛酸的濃度，縮短了氧化時間，並使尿囊素產率達到40 % 。
