Abstract
A composition is provided to comprise a non-aqueous medium and a 3,4-oxypyridinone compound of structure (I): with each A being oxygen and/or sulfur, and with a variety of substituents at R1-R5 to enable a solution or an at least semi-stable emulsion to be formed in the non-aqueous medium. Methods of use are included herein, which may be focused on situations where the composition can be used as a lubricant and/or coolant.
Claims22
A composition comprising a non-aqueous medium and a 3,4-oxypyridinone compound of structure (I):
- wherein:
- all A's are oxygen atoms;
- R1 is hydrogen;
- a linear, branched, and/or cyclic C1-C12 hydrocarbyl moiety;
- an ether-containing linear, branched, and/or cyclic C1-C12 moiety;
- another 3,4-oxypyridinone connected as an ether at a meta position to the ring nitrogen thereof, or a combination thereof;
- R2 is hydrogen;
- a linear, branched, and/or cyclic C1-C12 hydrocarbyl moiety;
- an ether-containing linear, branched, and/or cyclic C1-C12 moiety;
- an aldehyde-containing linear, branched, and/or cyclic C1-C12 moiety;
- a nitrile-containing linear, branched, and/or cyclic C1-C12 moiety;
- or a combination thereof;
- R3 is an oligomeric and/or polymeric moiety containing repeat units comprising reacted pendant to one or more repeat units, optionally olefins, hydrogenated conjugated dienes, or combinations thereof, at least one of which repeat units is attached to the ring nitrogen, optionally with a spacer, a number average molecular weight of which oligomeric and/or polymeric moiety is from 700 g/mol to 30000 g/mol;
- R4 is hydrogen;
- a linear, branched, and/or cyclic C1-C12 hydrocarbyl moiety;
- an ether-containing linear, branched, and/or cyclic C1-C12 moiety;

- or a combination thereof;
- and
- R5 is hydrogen;
- an R1-A- moiety;
- or a combination thereof;
- or R4 and R5 may together comprise from 3 to 12 carbons and form a (hetero)cyclic ring structure,
- wherein:
- all A's are oxygen atoms;
- R1 is hydrogen;
- a linear, branched, and/or cyclic C1-C12 hydrocarbyl moiety;
- an ether-containing linear, branched, and/or cyclic C1-C12 moiety;
