Method for synthesizing low-viscosity PAO4 by high-purity linear alpha olefine through anhydrous AlCl3

The invention provides a method for synthesizing low-viscosity PAO4 by high-purity linear alpha olefine through anhydrous AlCl3. The method is characterized in that, in a hot 1-decene monomer, a catalyst is dropwise added, and then low-viscosity PAO4 base oil is synthesized, wherein the catalyst is selected from aluminium chloride anhydrous; the hot 1-decene monomer is heated to 90 DEG C or above. The invention provides the method for synthesizing the low-viscosity PAO4 by the high-purity linear alpha olefine through the anhydrous AlCl3. The industrial catalyst adopted by the method is low-price; the catalyst is easily obtained; further, the catalyst in a reaction process is easily treated; the reaction condition is mild; the low-viscosity PAO obtained through preparation is good in viscosity temperature characteristic. 本发明提供了种由高纯度线性α烯烃通过无水AlCl合成低粘度PAO4的方法，其特征在于：于热的1-癸烯单体中，滴加催化剂后，合成低粘度PAO4基础油；其中，所述催化剂选自无水三氯化铝；所述热的1-癸烯单体为加热至90℃以上。本发明提供了种由高纯度线性α烯烃通过无水AlCl合成低粘度PAO4的方法方法。本发明采用的工业催化剂廉价，该催化剂易于获得，且反应过程中的催化剂易于处理，反应条件
