Purification of products from the reaction media is often a major
challenge in biorefineary. Precipitation of the desired product
from the solution with close to 100% purity is uncommon in
biomass valorization, and this feature will significantly facilitate
post-treatment and reduce the process cost.

The three chemical reactions developed above bridge corn
stover lignin with TPA. On a lignin basis, 16.1 wt% of 4-
alkylphenols were obtained after the de-methoxylation step,
which can be converted into 14.8 wt% of 4-alkylbenzoic acids
via carbonylation, and finally to 15.5 wt% TPA after oxidation

(Figure S5. Of note, the yields of the 4-alkylbenzoic acids in our
2
study were obtained from a mimetic mixtures of 4-alkylphenols).
Based on this, we propose a conceptual design for the full
utilization of corn stover for polyethylene terephthalate and other
value-added applications (Figure S6). Lignin is converted into
lignin oil via reductive depolymerization and then transformed
into TPA based on the strategy developed in the current work.
Acid catalysis of polysaccharide offers a series of high-value
biomass platform molecules, such as glucose, xylose, 5-
hydromethylfurfural, furfural, levulinic acid, etc. Hydrogenolysis
of sugars affords ethylene glycol (EG) and propylene glycol,
which copolymerize with TPA to access 100% bio-based
polyethylene terephthalate (PET) and other plastics.
To summarize, we developed a new chemical route that could
be used to produce TPA from corn stover-derived lignin oil via
de-methoxylation, carbonylation and oxidation steps. A salient
feature is that TPA precipitates from the solution in the final step
in an almost pure form, avoiding any complex purification
process. This work provides an example of chemical funneling
and functionalization of complex lignin-derived monomers into a
single, value-added compound.
