Publication number: 20170009174Abstract: A composition that includes one or more compounds represented by the formula (R1)a(X)(R2)b wherein R1 and R2 are the same or different and are the residue of an alkyl group having from about 4 to about 40 carbon atoms, X is the residue of at least one polycyclic, heteroatom-containing, hydrocarbon compound, a is a value from 1 to about 8, and b is a value from 0 to about 8. The composition has a viscosity (Kv100) from about 2 to about 300 at 100° C. as determined by ASTM D-445, and a viscosity index (VI) from about ?100 to about 300 as determined by ASTM D-2270. The disclosure also relates to a process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method for improving oxidative stability of a lubricating oil by using as the lubricating oil a formulated oil containing the composition.Type: ApplicationFiled: June 30, 2016Publication date: January 12, 2017Inventors: Abhimanyu O. Patil, Kyle G. Lewis, Li Ren, Satish Bodige, Shuji Luo, Beth A. Winsett

Patent number: 9238599Abstract: 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.Type: GrantFiled: December 7, 2011Date of Patent: January 19, 2016Assignee: ExxonMobil Chemical Patents Inc.Inventor: Beth A. Winsett

Patent number: 9187384Abstract: This invention is directed to an improvement in the process for the production of alkylaromatic compounds that results in lower levels of residual unreacted materials in the final product. This invention comprises: 1) alkylation of an aromatic compound with an alkylating agent and a catalyst to produce an effluent stream comprising an alkylaromatic compound and unreacted materials; 2) heating the effluent stream; 3) stripping the effluent stream in a stripping device in the presence of steam; 4) separating a stripping stream from the stripping device, the stripping stream rich in unreacted materials; and 5) separating a product stream from the stripping device, the product stream rich in alkylated aromatic compound.Type: GrantFiled: December 13, 2011Date of Patent: November 17, 2015Assignee: ExxonMobil Chemical Patents Inc.Inventors: Beth A. Winsett, James I. Arnett, II, Kenwyn M. Leger, Brady A. Compton

Publication number: 20140274838Abstract: A method for improving thermo-oxidative stability and elastomer compatibility in an apparatus lubricated with a lubricating oil by using as the lubricating oil a formulated oil including a lubricating oil base stock. The lubricating oil base stock includes a di-alkylated aromatic base stock of the formula: (R1)—(R2)—(R1) wherein each R1 is the same or different and represents a C10-C30 alkyl group; R2 represents an aromatic moiety. The di-alkylated aromatic base stock includes at least 44 wt % dialkylate product. Thermo-oxidative stability and elastomer compatibility are improved as compared to thermo-oxidative stability and elastomer compatibility achieved using a lubricating oil base stock other than the di-alkylated aromatic base stock. A lubricating oil including the di-alkylated base stock of the above formula, and the di-alkylated aromatic base stock of the above formula.Type: ApplicationFiled: March 4, 2014Publication date: September 18, 2014Applicant: ExxonMobil Research and Engineering CompanyInventors: Kathleen Kim Cooper, Suzzy Chen Hsi Ho, Gary Christensen, Beth A.
