Preparation of Benzoyl peroxide: firstly, prepare the material of sodium hydroxide and oxydol. Next, drop benzoyl chloride into mixture with stirring at reaction temperature below 0 °C. Then keep the temperature about 0 °C for 2-3 hours with stirring. By means of stalling layered and drying at low temperature you can get the product.
Uses of Benzoyl peroxide: it can be used to test formaldehyde and bravery sterol. And it can be used as quality improver of flour, intermediates of fine chemical products, additives of grain and oil, vulcanization agent of xylene silicone rubber and kyle F-rubber, catalyst of free radicals halogenating and radical sensitization reaction. In addition, it can react with piperidine to get 1-benzoyloxy-piperidine. This reaction will need reagent dipotassium hydrogen phosphate and solvent dimethylformamide. The reaction time is 21 hours by heating. The yield is about 60%.
When you are using this chemical, please be cautious about it as the following:
This chemical is explosive when dry. It may cause fire when contact with combustible material. And ti is irritating to eyes, respiratory system and skin and harmful in contact with skin and if swallowed. In addition, it has risk of impaired fertility. It is toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Avoid exposure - obtain special instructions before use. It has refer to special instructions/safety data sheets. During using it, wear suitable protective clothing, gloves and eye/face protection. And keep away from combustible material. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. And in case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.). In additon, this material and its container must be disposed of as hazardous waste and must be disposed of in a safe way. You shuld keep container tightly closed and avoid release to the environment.
