| titleOfInvention | Preparation process of polystyrene initiator |
| abstract | The invention relates to a preparation process of a polystyrene initiator. The preparation process comprises steps as follows: a reaction: 3.5 parts of phenyl dimethylcarbinol peroxide is dropwise added to 2 parts of 27.5% hydrogen peroxide after the PH (potential of hydrogen) of 27.5% hydrogen peroxide is adjusted to 5.5 with sulfuric acid, 0.075 parts of perchloric acid is added to a product at the temperature of subzero 5 DEG C after a reaction ends, and a condensation reaction is performed; b, flash separation: an initial product of dicumyl peroxide is obtained after flash separation; c, drying; d, crystallization purification: recrystallization purification is performed through a purified solvent; e, filtration; d, drying: a pure product is obtained through vacuum drying, wherein the purified solvent is ethanol. According to the preparation process of the polystyrene initiator, the use is convenient, the efficiency of the process can be improved, the operation is simplified, and the effective quality of a product is further improved while safety and environmental protection are guaranteed. |
