【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、潤滑用油の製造方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for producing lubricating oil.

It is described that a polycyclic aromatic compound useful as a lubricating oil or the like is produced by quantification and then reacting the dimerized product with an aromatic hydrocarbon. The dimerization reaction is carried out using a fluorine-substituted aliphatic sulfonic acid, and more than 90% of the product is a styrene dimer.
本発明は、潤滑用油として好適なスチレンオリゴマーを
製造することを目的とする。The object of the present invention is to produce a styrene oligomer suitable as a lubricating oil.
本発明は、スチレンを、リン酸又は芳香族スルホン酸の

。The present invention is a method for producing a lubricating oil comprising a liquid styrene oligomer by polymerizing styrene in the presence of a 60 to 95% by weight aqueous solution of phosphoric acid or aromatic sulfonic acid.

である。The catalyst used for polymerization in the present invention is phosphoric acid or aromatic sulfonic acid, and the aromatic sulfonic acid is preferably para-toluenesulfonic acid. These catalysts must be used in the form of an aqueous solution of 60 to 90% by weight; liquid styrene oligomers cannot be obtained at concentrations other than this. The amount of the aqueous catalyst solution used is approximately 1 to 4% by weight based on styrene.
また、重合温度は80〜120℃程度であり、好ましく
は90〜110℃である。重合はオリゴマーの数平均分

が、重合時間としては1〜5時間程度、好ましくは1.
5〜3時間である。Moreover, the polymerization temperature is about 80 to 120°C, preferably 90 to 110°C. The polymerization is preferably carried out so that the number average molecular weight of the oligomer is 150 to 300, and the polymerization time is about 1 to 5 hours, preferably 1.5 hours.
It takes 5 to 3 hours.

ない。After the polymerization reaction is completed, it is neutralized and washed to obtain a liquid oligomer. If neutralization is carried out using slaked lime, it will react with the catalyst to form an insoluble salt, which will be easily separated. Note that, if necessary, this oligomer may be purified by distillation or the like, or its molecular weight may be made uniform, but this is not advantageous because of its high boiling point.

It is expected to be used as a compatibilizer with lubricating oils such as polyalphaolefin oils. The lubricating oil of the present invention includes:
If necessary, additives or other lubricating oils may be mixed to form a lubricating oil.
