In the C4-MTBE-methanol ternary system, when water/ stock ≤ 1.0/ 2.0 ( by volume), the ratio of C4 to MTBE ( by weight) strongly affected the residual methanol contained in the extraction C4 raffinate. 在C4、MTBE和甲醇三元物料试验中,当水/物料(体积比)≤1:2时,C4/MTBE(重量比)是影响萃余相中甲醇含量的主要因素。
Though the extraction effect taking the extract oil as solvent is not as good as the one taking the pure furfural as solvent, the qualities of the raffinate oil and the extract oil can be assured by adjusting the operation conditions. 尽管以抽出液为溶剂时,其抽提效果不如纯糠醛的好,但可以通过调整操作条件来保证抽余油的质量及抽出油的质量。
The extraction raffinate can be concentrated by one-stage evaporation to obtain sulfuric acid with 80% of mass fraction. 萃余液经一次性蒸发浓缩,可得到质量分数80%以上的硫酸。
