    摘要: Disclosed herein is a method of making a PAO using tetradecene and particularly mixtures comprising 1-hexene, 1-decene, 1-dodecene, and 1-tetradecene, characterized by a low viscosity and excellent cold temperature properties, using a promoter system comprising an alcohol and an ester. In embodiments, the product has properties similar to those obtainable using a feed of solely 1-decene.

    摘要: A process for reducing boron trifluoride usage and emissions associated with PAO manufacture, the process comprising distilling a portion of the crude PAO product containing a boron trifluoride-organic catalyst at a temperature sufficient to cause the boron trifluoride-organic catalyst to dissociate to produce an overhead stream comprising uncomplexed boron trifluoride and an uncomplexed organic catalyst component, contacting the uncomplexed boron trifluoride and uncomplexed organic catalyst component in a condenser column having an internal structure that increases the recombination of the uncomplexed boron trifluoride and uncomplexed organic catalyst component to form a recycle boron trifluoride-organic catalyst.
