Patent number: 8329958Abstract: A simple chain-extending approach was established for the scale-up of the monoprotected monodisperse PEG diol materials. Reactions of THP-(OCH2CH2)n—OMs (n=4, 8, 12) with a large excess of commercially available H—(OCH2CH2)n—OH (n=1-4) under basic conditions led to THP-(OCH2CH2)n—OH (n=5-15). Similarly, Me-(OCH2CH2)n—OH (n=4-11, 13) were prepared from Me-(OCH2CH2)n—OMs (n=3, 7, 11). For the chain elongation steps, 40-80% yields were achieved through extraction purification. PEG oligomer libraries I and II were generated in 50-95% overall yields by alkylation or acylation of THP-(OCH2CH2)n—OH (n=1-15) followed by deprotection. Alkylation of Me-(OCH2CH2)n—OH (n=1-11, 13) with X—(CH2)m—CO2R (X=Br or OMs) and subsequent hydrolysis led to PEG oligomer library III in 30-60% overall yields. Combinatorial purification techniques were adapted to the larger-scale library synthesis.

Publication number: 20110263469Abstract: A process for making a poly(alkyl epoxide). The process has the step of polymerizing one or more alkyl epoxide monomers in the presence of a cationic catalyst according to the following sequences: wherein R1, R2, R3, and R4 are hydrogen or alkyl moieties that, taken together, have a total of 1 to 80 carbons; wherein any of R1, R2, R3, and R4 can be linear or branched if it is an alkyl moiety; wherein “m” is an integer from 1 to 4; and wherein “n” is an integer from 2 to 120. There is also another process for making a poly(alkyl epoxide) using an initiator. There are also poly(alkyl epoxides). There is also a lubricant composition having a first lubricant base stock of one or more poly(alkyl epoxides) and a second lubricant base stock different than the first lubricant base stock.Type: ApplicationFiled: April 23, 2010Publication date: October 27, 2011Applicant: ExxonMobil Research and Engineering CompanyInventors: Abhimanyu Onkar Patil, Satish Bodige
