• Controlled formation of olefin oligomers using boron trifluoride and a hydroxy carbonyl
  申请人：CHEVRON CHEMICAL COMPANY

  公开号：EP0678493A2

  公开（公告）日：1995-10-25

  An oligomer is made by contacting a straight-chain, α-olefinic monomer with boron trifluoride and a hydroxy carbonyl promoter. The hydroxy carbonyl is preferably a β-hydroxy-ketone, such as 4-hydroxy-4-methyl-2-pentanone. A second promoter can be used in conjunction with the boron trifluoride and the hydroxy carbonyl promoter. Possible secondary promoters include aldehydes, alcohols, alcohol alkoxylates, carboxylic acids, ethers, ketones, and their mixtures. Preferably the oligomer product has a kinematic viscosity at 100° C of less than 1.7 cSt; has a dimer to trimer and higher oligomer ratio of at least 1:1; and is at least 90 wt. % dimer and trimer of the monomer.

  将直链α-烯烃单体与三氟化硼和羟基羰基促进剂接触，可制成低聚物。羟基羰基最好是 β-羟基酮，如 4-羟基-4-甲基-2-戊酮。第二种促进剂可与三氟化硼和羟基羰基促进剂一起使用。可能的第二促进剂包括醛、醇、醇烷氧基化物、羧酸、醚、酮及其混合物。低聚物产品在 100 摄氏度时的运动粘度最好小于 1.7 厘斯；二聚物与三聚物及更高的低聚物之比至少为 1:1；二聚物和三聚物的重量至少占单体的 90%。
