Maximising opportunities in supercritical chemistry: the continuous conversion of levulinic acid to gamma-valerolactone in CO(2).
Phase behaviour is manipulated during the hydrogenation of aqueous levulinic acid in supercritical CO(2) to separate almost pure gamma-valerolactone from water and unreacted acid with reduced energy requirements compared to conventional processing.
