More Information
Summary:The invention discloses a synthetic method of lubricating oil base oil. The method comprises the following steps: simultaneously adding high-carbon olefin and ethylene into a high-pressure white steelpolymerization reaction kettle, adding a Ziegler-Natta catalyst into the reaction kettle, starting a reaction, and controlling conditions in a polymerization process; after the reaction is finished,pressing the material into a second reaction kettle through nitrogen (or cooling to room temperature in the same reaction kettle) while adding an AlCl3 catalyst into the material, and controlling theadding amount of the catalyst and the polymerization reaction conditions; and after the reaction is finished, emptying and depressurizing the reaction kettle, removing the residual catalyst from the obtained crude product through an alkali washing process, removing the unreacted high-carbon olefin through pressure reducing distillation, and carrying out structural characterization determination onthe product obtained after
