Abstract

See full text

This invention is directed to a new process for making an alkylaromatic compound. In an embodiment of this invention, the process is directed to selective synthesizing an alkylaromatic compound comprising a high amount of dialkylate product. In general, this process involves contacting at least one alkylatable aromatic compound with an alkylating agent and a catalyst under suitable reaction conditions such that the resulting reactor effluent prior to any stripping step may be characterized by a dialkylate product content of at least 44 wt % and a trialkylate and higher polyalkylate product content of no more than 20 wt %. The alkylaromatic compounds produced have excellent thermal and oxidative stabilities, good additive solvency, and improved seal compatibility while maintaining good VI and low temperature properties. They are useful as lubricant basestocks and lubricant additives.
