| titleOfInvention | Butyl rubber liquid catalytic polymerization system |
| abstract | The invention relates to a butyl rubber liquid catalytic polymerization system, and belongs to the technical field of petrochemical industry. Isobutene and isoprene are used as raw materials, methyl chloride is used as a solvent, and a liquid catalyst is used as a catalyst to synthesize butyl rubber, wherein the liquid catalyst comprises ethyl aluminum dichloride, tert-butyl alcohol and HCl, the content of the ethyl aluminum dichloride in the solvent is 0.2-0.8%, the content of the tert-butyl alcohol in a mixed feed is 10-100 ppm, and the content of the HCl in the solvent is 30-400 ppm. The liquid catalyst adopts continuous batching, all materials are in a closed device and a pipeline system, and the whole process adopts automatic control, thereby not only reducing the labor intensity of personnel, but also avoiding the influence on the environment; the catalyst makes the polymerization reaction proceed steadily and mildly, and improves the continuous operation period and product performance of the reaction kettle of the polymerization system. |
