SPRAY OXIDATION PROCESS FOR PRODUCING 2,5-FURANDICARBOXYLIC ACID FROM HYDROXYMETHYLFURFURAL |
摘要 |
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. |

1. A process 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, comprising the steps of:
spraying the feed into a reactor vessel as a mist; supplying an oxidant to the reactor vessel; 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. |
