Abstract
A method for producing an α-olefin oligomer, the method including subjecting α-olefin to oligomerization reaction to produce an α-olefin oligomer mixture, carrying out distillation separation of α-olefin oligomer having less than n carbon atoms in the mixture to obtain a distillation residue containing α-olefin oligomer having n or more carbon atoms, and then carrying out a step of removing high molecular weight molecules from the distillation residue.
Claims11
A method for producing an α-olefin oligomer, the method comprising:
- subjecting ethylene to an oligomerization reaction to produce an α-olefin oligomer mixture;
- carrying out a distillation separation of an α-olefin oligomer having less than n carbon atoms in the α-olefin oligomer mixture to obtain a distillation residue containing an α-olefin oligomer having n or more carbon atoms, where n is 26 or 30;
- and then
- removing a high molecular weight molecule having a weight average molecular weight of 100,000 or more from the distillation residue such that the distillation residue, after the removing of the high molecular weight molecule, has a cloud point, measured according to JIS K 2269, of 100° C. or less.
