実験手順

Into a 300 ml pressure-resistant glass autoclave were charged 10 g of isobutylene, 10 g of 1-butene, 50 g of sulfuric acid and 50 g of water, and the mixture was stirred at 60° C. at a pressure of 8.5 atms for one hour. As a result, isobutylene was hydrated to form tert-butanol with the conversion of 90% and the selectivity to tert-butanol of 92%. At the same time, diisobutylene and the trimer of isobutylene were produced at a yield of 2% and 6%, respectively, and 1-butene was hydrated to form sec-butanol at a yield of 4%.
