Abstract
This disclosure relates to ester compounds derived from neo-acids, lubricating oil base stocks comprising such ester compounds, lubricating oil compositions comprising such ester compounds, and method for making such compounds and/or base stocks. The lubricating oil base stocks comprising the ester compounds exhibit desirable lubricating properties such as polarity and oxidation stability.
Claims25
A compound having the following formula (F-I):
- wherein R1 and R2 are each independently a hydrocarbyl group comprising at least two (2) carbon atoms;
- and
- R3 is a substituted or unsubstituted hydrocarbyl group.
A lubricating oil composition comprising a compound having the following formula (F-I):
- wherein R1 and R2 are each independently a hydrocarbyl group comprising at least two (2) carbon atoms;
- and
- R3 is a substituted or unsubstituted hydrocarbyl group.
A process for making an ester product comprising a compound having the following formula (F-I):
- wherein R1 and R2 are each independently a hydrocarbyl group comprising at least two carbon atoms;
- R3 is a substituted or unsubstituted hydrocarbyl group;
- the method comprising:
- reacting a neo-acid having a formula (F-II) and/or an anhydride thereof with an alcohol having a formula (F-III) below in the presence of an acid catalyst to obtain a reaction mixture, where R1, R2, and R3 correspond to the R1, R2, and R3 in formula (F-I), respectively:
- R3—OH (F-III), and
- obtaining the ester product from the reaction mixture.
