WebOzonolysis is usually carried out by passing a stream of ozonised oxygen (5–15% ozone) through a solution of the substrate at a low temperature (−30 to −70 °C) until the release of iodine from an indicator solution of acidified potassium iodide reveals the persistence of ozone in the exit gases. WebThese procedures all begin with a low temperature ozonolysis in the presence of methanol. Once the double bond is completely converted to the initial ozonide product, as evidenced by the characteristic blue color of unreacted ozone, the excess ozone is removed by a stream of nitrogen.
