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.
Provided is a two-step method of producing a compound of chemical formula 1 in the presence of an alcohol solvent and a Group 3B metal catalyst or a salt thereof, comprising a first step comprising alkylation or isomerization of an aldohexose-containing substrate to obtain an intermediate, and a second step comprising dehydration of the intermediate to produce a compound of chemical formula 1. Preferably, additional solvent and/or catalyst are not added in the second step.
