Process for preparing alkylated oil

[0042] The toluenesulfonic acid ionic liquid catalyst of 6.0 grams of pyridine butylsulfonic acid is added in the autoclave with stirring, with N 2 Pressing pressure to 0.5MPa, feed 80g of isobutane and butene-1 mixed raw material, the alkene ratio in the raw material is 6:1. Start stirring, raise the temperature to 70°C within 30min, and use N 2 Ensure the pressure is 1.6MPa, and react for 0.5h. After the reaction, cool down and release the pressure. The reaction solution is poured into a separatory funnel and left to stand for stratification, the lower layer is the catalyst phase, and the upper layer is the alkylated oil phase.

[0044] Add 2.0% trifluoromethanesulfonic acid ionic liquid catalyst of 2-butylpyridine propylsulfonate into the autoclave with stirring, and use N 2 Pressing pressure to 0.5MPa, feed 80g of isobutane and butene-1 mixed raw material, the alkene ratio in the raw material is 6:1. Start stirring, raise the temperature to 70°C within 30min, and use N 2 Ensure the pressure is 1.6MPa, and react for 0.5h. After the reaction, cool down and release the pressure. The reaction solution is poured into a separatory funnel and left to stand for stratification, the lower layer is the catalyst phase, and the upper layer is the alkylated oil phase.

[0046] The toluenesulfonic acid ionic liquid catalyst of 6.0 grams of 1-butyl imidazole sulfonic acid butyl ester is added in the autoclave with stirring, with N 2 Pressing pressure to 0.5MPa, feed 80g of mixed raw material of isobutane and butene-1, the ratio of alkene in the raw material is 10:1. Start stirring, raise the temperature to 70°C within 30min, and use N 2 Ensure the pressure is 1.6MPa, and react for 0.5h. After the reaction, cool down and release the pressure. The reaction solution is poured into a separatory funnel and left to stand for stratification, the lower layer is the catalyst phase, and the upper layer is the alkylated oil phase.
