| 摘要 |
The invention relates to a method for the preparation of arylated poly-alpha-olefins, which comprises the steps of: a) oligomerising one or more alpha-olefin, preferably a C6- C20 alpha-olefin, preferably in the presence of an acidic catalyst such as promoted BF3, AlCl3, triflic acid, BCl3 or AlBr3, to form olefin dimers and higher oligomers; and b) arylating the olefin oligomers with an aromatic compound such as benzene, alkyl benzene, naphthalene or alkylated naphthalene, preferably in the presence of a catalyst such as promoted BF3, AlCl3, triflic acid, BCl3, AlBr3 or an acidic zeolite. Said arylated poly-alpha-olefins are useful as base fluids or additives in synthetic lubricants. <IMAGE> |
