Abstract: The invention is directed to a process for the continuous preparation of a cycloadduct product from the reaction of a furanic with a dienophile, comprising heating a first liquid feed stream comprising the dienophile and a solvent in which the dienophile is dissolved; providing a second liquid feed stream comprising the furanic; leading the first liquid feed stream and the second liquid feed stream into a continuous reactor to produce a product solution stream comprising the cycloadduct product; and leading the product solution stream to an product isolation zone to produce an isolated cycloadduct product. A further aspect of the invention is an apparatus for carrying out this reaction.
