| titleOfInvention | Preparation method of oligomeric isobutene for synthesizing squalane |
| abstract | The invention relates to a preparation method of oligomeric isobutylene for synthesizing squalane, which adopts novel lanthanide triflate and cocatalyst to catalyze isobutylene polymerization, and an auxiliary agent is added in the polymerization process to prepare oligomeric isobutylene with molecular weight of 295-350, which can be used for synthesizing squalane; after the polymerization reaction is finished, the product is layered after the water quenching reaction, the polyisobutylene is obtained by oil phase separation, the synthetic squalane product can be obtained by hydrogenation, and the catalyst in the water phase is repeatedly used after being crystallized. The method can well control the molecular weight of the polyisobutene, the product yield is more than or equal to 85 percent, the molecular weight distribution is narrow, the catalyst can be repeatedly applied, the corrosion problem is avoided, the method is not sensitive to water, the raw materials do not need to be dried, and the nitrogen protection is not needed in the reaction. |
