Abstract
Iso-butylene과 황산 수용액의 흡수 반응에 대한 실험연구로서 기상의 iso-butylene과 액상의 황산을 연속적으로 향류 접촉시키기 위해 충전탑을 이용하였다. Iso-butylene의 흡수율을 황산의 농도 변화와 반응온도 변화에 따라 측정한 결과, 황산의 최적 농도는 50 wt%로, 최적 반응온도는 30 ℃로 밝혀졌다. 유량의 변화가 흡수율에 미치는 영향을 iso-butylene과 황산의 유량을 각각 변화시켜가며 조사한 결과, iso-butylene의 흡수율이 최대가 되는 최적 조건이 존재함을 보였다. 환류비가 흡수율에 미치는 영향을 연구하기 위해 액상의 반응혼합물 일부를 환류시켜 같은 실험을 반복하였다.

Presented here is an experimental study for the absorption and reaction between iso-butylene and sulfuric acid. A packed column was employed to establish a continuous countercurrent contact between gaseous iso-butylene and liquid sulfuric acid.
Fraction of iso-butylene absorbed was measured not only for various concentrations of sulfuric acid but also at various reaction temperatures. The optimum level of sulfuric acid concentration turned out to be 50 wt% whereas the optimum reaction temperature was found to be 30 ℃. The effect of flow rates on the fraction absorbed was examined by using various sets of flow rates of iso-butylene and sulfuric acid. The result showed that there existed an optimum set of flow rates for which the fraction of iso-butylene absorbed reached a maximum. Similar procedure was repeated with recycle stream of liquid phase to study the effect of recycle ratio on the fraction absorbed. The influence of tert-butyl alcohol contained in the liquid phase was also measured and discussed.
