Abstract
Various embodiments disclosed relate to isomerization of muconic acid. In various embodiments, the present invention provides a method of forming trans,trans-muconic acid. The method includes heating a starting material composition to form a product composition including trans,trans-muconic acid. The starting material composition includes cis,cis-muconic acid, cis,trans-muconic acid, or a combination thereof. The starting material composition also includes an electrophilic compound, an organic solvent, or a combination thereof.
Claims18
A method of forming trans,trans-muconic acid, the method comprising:
- heating a starting material composition to form a product composition comprising trans,trans-muconic acid, wherein the starting material composition comprises
- cis,cis-muconic acid, cis,trans-muconic acid, or a combination thereof,
- wherein the starting material further comprises at least one of La3+ salt, AlBr3, AlCl3, and DMSO.
A method of forming trans,trans-muconic acid, the method comprising:
- heating a starting material composition to form a product composition comprising trans,trans-muconic acid, wherein the starting material composition comprises
- cis,cis-muconic acid, cis,trans-muconic acid, or a combination thereof, and
- (A), (B), or (C), or both (A) and (B):
- (A) a La3+ salt,
- (B) AlBr3, AlCl3, or a combination thereof, and a polar aprotic solvent,
- (C) dimethylsulfoxide (DMSO), and about 0 wt % to about 20 wt % water, D2O, or a combination thereof, wherein the starting material composition is substantially free of solvents other than the DMSO and the water and D2O.
