Production of ketone-based biopolymers from catalytic fast pyrolysis of biomass
The present disclosure relates to a composition that includes where R 1 and R 2 include at least one of a hydrogen, a hydroxyl group, and/or an alkyl group, R 3 and R 4 include at least one of hydrogen, a hydroxyl group, an alkyl group, and/or a ketone, and 1≤n≤2000.
1. A composition comprising:
at least one of
wherein 1<n≤2000.
2. The composition of claim 1 , further comprising an end-group derived from an alcohol.
3. The composition of claim 1 , wherein the composition is bioderived as determined by ASTM-D6866.
4. A method comprising:
a first reacting of a diether with a diol to form a polymer comprising
at least one of
wherein 1<n≤2000.
5. The method of claim 4 , further comprising:
a second reacting of a cyclic ketone with an alcohol to form the diether, wherein:
the second reacting is performed prior to the first reacting.
6. The method of claim 5 , wherein the first reacting produces the alcohol.
7. The method of claim 5 , further comprising:
prior to the second reacting, separating the cyclic ketone from a mixture comprising compounds derived from catalytic fast pyrolysis.
8. The method of claim 4 , wherein the separating comprises at least one of distillation or liquid-liquid separation.
