Potassium Iodide → HCID 53798357, compound

Participants

Reaction Steps

A mixture of 454 g. (1.86 mol) of dibromohexane, 128.5 g of potassium carbonate and about 0.2 g of potassium iodide in 460 ml of acetone is heated to the boil. A solution of 36.9 g. (0.186 mol) of p-hydroxyazobenzene in 330 ml of acetone is then added in several portions. In order to prevent delays in boiling, the mixture is stirred constantly. After about 4.5 hours, the reaction is terminated, the still-hot solution is filtered, and a little dye is washed out of the filtered-off inorganic salts using a little acetone. The acetone is removed from the solution under slightly reduced pressure. The excess dibromohexane is subsequently removed in an oil-pump vacuum.
