PROCESS FOR THE CONVERSION OF A CARBOHYDRATE-CONTAINING FEEDSTOCK

摘要

A carbohydrate-containing feedstock is converted in a process, which process comprises contacting the feedstock in a first step with an alcohol in the presence of a first acid catalyst at a temperature below 100 °C to yield an intermediate product, and contacting at least part of the intermediate product in a second step with an alcohol in the presence of a second acid catalyst at a temperature of at least 100 °C. Products of such conversion may include hydroxymethylfurfural, hydroxymethylfurfural ethers, levulinic acid, esters thereof and furfural.
