A process is provided for carrying out an oxidation on a sprayable feed including a furanic substrate to be oxidized and a catalytically effective combination of cobalt, manganese, and bromide components for catalyzing the oxidation of the furanic substrate, which process comprises spraying the feed into a reactor vessel as a mist, supplying an oxidant, reacting the furanic substrate and the oxidant, and managing the exothermic temperature rise due to the reaction through a selection and control of the operating pressure within the reactor vessel. A crude dehydration product from the dehydration of fructose, glucose or both, including 5-hydroxymethylfurfural, can be directly oxidized by the process to produce 2,5-furandicarboxylic acid in surprisingly increased yields.
A process for carrying out an oxidation on a sprayable feed including a crude dehydration product of natural hexose as a furanic substrate to be oxidized and a catalytically effective combination of cobalt, manganese, and bromide components for catalyzing the oxidation of the furanic substrate, comprising the steps of:
A process for making 2,5-furandicarboxylic acid from fructose, glucose or a combination of fructose and glucose, comprising:
