摘要： A process for producing a synthetic hydrocarbon especially useful as a base for high performance motor oils. The material is the oligomerization product of a C8-C16 α-olefin monomer and has a unique selective product distribution emphasizing tetramers and pentamers. This distribution is achieved by using a catalyst comprising boron trifluoride and a long, straight-chain alcohol promoter, such as 1-hexanol.

摘要： A process for making an oligomer comprises contacting an olefinic monomer with boron trifluoride and a cpd. selected from hydroxyalkyl ketone and hydroxyalkyl aldehyde. The process is carried out at 0-200[deg]C and a pressure of from atmospheric up to 1000 psig. The olefinic monomer is a straight-chain, alpha-olefinic monomer contg. 6-20C, pref. 6-12C, more pref. 8-10C. The promoter cpd. is a hydroxyalkyl ketone, pref. contg. 1-6C, where the ketone gp. is pref. methyl ketone or ethyl ketone; suitable cpds. are hydroxy acetone, 1-hydroxy-2-butanone, 3-hydroxy-2-butanone, 3-hydroxy-3-methyl-2-butanone and 4-hydroxy-4-methyl-2-pentanone. More pref., the hydroxyl gp. is attached to a tert. carbon, and the most preferred ketone is 4-hydroxy-4-methyl-2-pentanone. The oligomer prod. has a kinematic viscosity at 100[deg]C of less than 3.6 cSt, pref. less than 2.0 cSt, more pref. less than 1.7 cSt. The ratio of dimer to the sum of trimer and higher oligomer is at least 0.5:1, pref. at least 1:1 and the prod. contains at least 70 wt.%, pref. at least 80 wt.%, more pref. at least 90 wt.% dimer and trimer before removal of unreacted monomer. A second promoter can be used in conjunction with the BF3 and the hydroxy carbonyl promoter. The second promoter is an aldehyde, alcohol, alcohol alkoxylate, carboxylic acid, ether, ketone or mixt. of these, pref. an alcohol such as methanol.

摘要： An oligomer is made by contacting an olefinic monomer with a catalyst comprising boron trifluoride, an alcohol alkoxylate, and a ketone. In one embodiment, the olefinic monomer is a straight-chain, alpha -olefinic monomer containing from 8 to 12 carbon atoms, the alcohol alkoxylate is 2-ethoxyethanol, the ketone is methyl ethyl ketone, and the oligomer product has a kinematic viscosity at 100 DEG C of less than 1.7 cSt. Before removal of unreacted monomer, the oligomer product is at least 50 wt. % dimer, at least 80 wt. % dimer plus trimer, and less than 3.25 wt. % tetramer and greater.
