Sulfuric Acid → HCID 88596644, compound

Participants

Reaction Steps

One hundred milliliters of 20% fuming sulfuric acid is charged into a 500 mL Erlenmeyer flask. With magnetic stirring, 60 g of BBOT is added in small portions. The reaction is exothermic. After the addition is complete, the reaction mixture is heated to 90°-100° C. for two hours. The reaction is then quenched by pouring the reaction mixture onto 500 g of crushed ice. A brown product precipitates as a fine powder. The product is collected on a fritted-glass Buchner funnel. The product is then washed by stirring it in 200 mL of 1N hydrochloric acid. Washing is prepared several times. The product is then dried in a vacuum oven at 60°-70° C. Typical yields are 75-80 g (89-93%).
