Methods can include making and formulating compositions containing ether ester compounds derived from neo-alcohols.
Claims23
A compound of the structural Formula F-I:
- wherein R1 and R2 are independently each a hydrocarbyl group comprising at least 2 carbon atoms;
- and R3 is a glycol ether or a polyglycol ether.
A lubricating oil composition comprising a compound defined by the structural Formula F-I:
- wherein
- R1 and R2 are independently each a hydrocarbyl group comprising at least 2 carbon atoms;

A method for making an ester compound of the structural Formula F-I:
- where R1 and R2 are independently each a hydrocarbyl group comprising at least two carbon atoms;
- and R3 is a glycol ether or a polyglycol ether, the method comprising the steps of:
- providing a neo-alcohol of the structural Formula F-II:
- wherein R1 and R2 are the same as the R1 and R2 of Formula F-I, respectively;
- reacting the neo-alcohol with an acid of the structural Formula II:
- wherein R3 is the same as the R3 of Formula F-I, and/or an anhydride of the acid, in the presence of an acid catalyst to obtain a product mixture;
- and
- obtaining the ester compound from the product mixture.
