Iodination of propane
WebDuring the reactions with ethane and propane the initially formed iodides decomposed to olefins and hydrogen iodide. These reactions occurred 5–10 times more rapidly than would be expected from published data on the homogeneous pyrolysis of iodides, and were probably heterogeneous in our system. WebThe reaction between iodine and propanone proceeds in acid solution. The acid acts as a catalyst. I2(aq) + CH3COCH3 (aq) ˜ CH3COCH2I(aq) + H + (l)+ I ¯ (ag ) The rate can be …
