Process for the isolation of levulinic acid |
abstract |
The invention relates to a process for the isolation of levulinic acid from an organic solution, comprising washing said organic solution with an alkaline aqueous stream to yield a washed organic solution; subjecting the washed organic solution to a distillation to yield a distillate and a distillation residue; and recovering levulinic acid from the distillate or the residue. This process may result in high yields of levulinic acid. |
