Abstract
Provided herein are compounds of the formula: in which n is an integer equal to or greater than 1; R2 is selected from hydrogen and optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched; and R1, R3, and R4, independently for each occurrence, are selected from optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched, wherein compositions comprising the compounds are characterized by particular combinations of values for estolide number, kinematic viscosity, and pour point. Also provided are compositions containing the compounds and methods of making both the compounds and compositions thereof.
Claims30
A composition comprising two or more estolide compounds, said composition having:
- an EN selected from an integer or fraction of an integer that is equal to or greater than 4, wherein the EN is the average number of estolide linkages in compounds according to Formula I;
- a kinematic viscosity equal to or greater than 200 cSt when measured at 40° C.;
- and
- a pour point equal to or lower than −40° C.,
- wherein said two or more estolide compounds are selected from compounds of Formula I:
- wherein
- x is, independently for each occurrence, an integer selected from 0 to 20;
- y is, independently for each occurrence, an integer selected from 0 to 20;
- n is an integer selected from 0 to 12;
- R1 is an optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched;
- and
- R2 is an optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched,
- wherein each fatty acid chain residue of said two or more estolide compounds is independently optionally substituted.
