Webto the 95% ethanol/water mixture. Now the benzene/water/ ethanol azeotrope evaporates away irst. Excess benzene must be added to make sure that all of the water is boiled away in the azeotrope. After the water is gone, the benzene/ ethanol azeotrope is distilled off at 67.8°, leaving just pure ethanol behind (bp 78.2°). [There are a number of ... WebUnder the optimal reaction conditions, the conversion of SBAC was 89.30%. In addition, in order to enhance the conversion of SBAC, reactive distillation was carried out in the presence of [HSO 3-PMIM]HSO 4 as catalyst. A high conversion of the SBAC of 97.72% was obtained under the optimal reaction conditions.
