Preparation of Chloroparaffin by Photo-catalytic Method |
| |
| Abstract: | Set up for photo catalytic chlorination of paraffin was built. The photo catalytic reaction characteristics for chlorination of paraffin had been investigated, such as the choice of light sources, the way for initiation and the controlling methods for photo catalytic reaction. The results show that the optimum wave length for initiation is 340nm, that the best temperature for initiation is 60～80℃, and that water and air are effective termination factors. Under these optimal conditions, the reaction time for chlorinated paraffin 52 is 6～7 hours. |
