Oligomerized mono olefins particularly suitable as a major component of lubricant compositions (optionally after hydrogenation) can be prepared by contacting a mixture of mono olefins with a catalyst. The mono olefins comprise a mixture containing at least 99 weight % of internal mono olefins having 9 to 24 carbon atoms generally with their double bond randomly distributed in their carbon chain. The catalyst comprises boron trifluoride, and optionally a promoter selected from alcohols, carboxylic acids, and water.
通过将单烯烃混合物与催化剂接触,可以制备特别适合作为润滑油组合物主要成分的低聚单体烯烃(可选择在氢化之后)。单烯烃包括一种混合物,其中含有至少 99 重量百分比的内部单烯烃,这些单烯烃通常具有 9 至 24 个碳原子,其双键在碳链中随机分布。催化剂包括
三氟化硼和选自醇、
羧酸和
水的
促进剂。
