The invention provides neo acids (NAs) and derivatives thereof. Also provided is a method for producing a NA, comprising hydrodeoxygenation (HDO) of a furan-containing neo acid (FNA) in the presence a metal triflate and a hydrogenation catalyst. The NA production method may further comprise hydroxyalkylation/alkylation (HAA) of 2-alkylfuran with levulinic acid or pyruvic acid in the presence of an acid catalyst, and at least one of 2-alkylfuran, levulinic acid and pyruvic acid may be from a renewable carbon source. The NA may have a bio-based content in the range of 20-100% according to, for example, ASTM-D6866. Further provided are methods for producing branched alkanes (BAs), tertrahydrofuran-containing neo acid (THFNA) and furan-containing neo ester (FNE) and side products such as iso acids (IAs).
The compound of claim 1, wherein the compound is a furan-containing neo acid (FNA) having a structure of any one of formulae 1-4.
The compound of claim 1, wherein the compound is a furan-containing neo acid ring opening (FNA RO) having a structure of any one of formulae 5-8.
The compound of claim 1, wherein the compound is a neo acid (NA) having a structure of any one of formulae 9-12.
The compound of claim 1, wherein the compound is an iso acid (IA) having a structure of any one of formulae 13-16.
The compound of claim 1, wherein the compound is a branched alkane (BA) having a structure of any one of formulae 17-20.
The compound of claim 1, wherein the compound is a tertrahydrofuran-containing neo acid (THFNA) having a structure of any one of formulae 21-24.
The compound of claim 1, wherein the compound is a furan-containing neo ester (FNE) having a structure of any one of formulae 25-28.
A method for producing a neo acid (NA), comprising hydrodeoxygenation (HDO) of a furan-containing neo acid (FNA) in the presence a metal triflate and a hydrogenation catalyst.
A method for producing a branched alkane (BA), comprising hydrodeoxygenation (HDO) of a furan-containing neo acid (FNA) in the presence of a solid acid supported metal-metal oxide catalyst or a physical mixture of a metal-based catalyst with a solid acid.
A method for producing a tetrahydrofuran-containing neo acid (THFNA), comprising hydrogenation of a furan-containing neo acid (FNA) in the presence of a hydrogenation catalyst.
(canceled)
A method for producing a furan-containing neo ester (FNE), comprising esterification of the FNA with an alcohol.
