The absorption and reaction of isobutene in sulfuric acid yielding tert-butanol was studied in a bubble column of 4.6 cm diameter and 105 cm length. The inlet concentration of acid was varied from 28.5 to 56.9 wt%. A simple absorption model was used which shows that the absorption rate depends on th
